- All of the cryptographic libraries included in phpseclib use mcrypt, if available, and an internal implementation - if it's not. The libraries all use a common interface although some functions, for some algorithms, carry with - with them certain caveats. Those that do not have caveats attached (or have relatively few attached) are - described below. If you don't know which one to use, try Crypt_TripleDES. -

3.1.1. Dependencies

- The Crypt_* functions require, minimally, PHP 4.0.0. Crypt_TripleDES additionally requires Crypt/DES.php. -

3.1.2. setKey() and setIV()

- Sets the key and the initialization vector, respectively. If neither are set, each assumed to be equal to - some amount of null bytes. The initialization vector is only used in block ciphers and even then only - in CBC mode. If the key or the initialization vector are larger then the block size, they're truncated. - If they're smaller, they're padded with null bytes. -

3.1.3. setMCrypt()

- See php.net's entry on mcrypt_module_open. - The first parameter is equal to $algorithm_directory and the second, to $mode_directory. -

3.1.4. encrypt() and decrypt()

- Self-explanatory. Encrypts or decrypts messages. See the examples in the subsequent sections. -

3.1.5. enableContinuousBuffer() and disableContinuousBuffer()

- Say you have a 16-byte plaintext $plaintext and that you're using Crypt_DES. Using the default behavior, the two following code snippets - will yield different outputs: - 

    echo $des->encrypt(substr($plaintext, 0, 8));
-    echo $des->encrypt(substr($plaintext, 8, 8));
    echo $des->encrypt($plaintext);

- The solution is to enable the continuous buffer. Although this will resolve the above discrepancy, it creates - another, as demonstrated with the following: - 

    $des->encrypt(substr($plaintext, 0, 8));
-    echo $des->decrypt($des->encrypt(substr($plaintext, 8, 8)));
    echo $des->decrypt($des->encrypt(substr($plaintext, 8, 8)));

- With the continuous buffer disabled, these would yield the same output. With it enabled, they yield different - outputs. The reason is due to the fact that the initialization vector's change after every encryption / - decryption round when the continuous buffer is enabled. When it's disabled, they remain constant. - - Put another way, when the continuous buffer is enabled, the state of the Crypt_DES() object changes after each - encryption / decryption round, whereas otherwise, it'd remain constant. For this reason, it's recommended that - continuous buffers not be used. They do offer better security and are, in fact, sometimes required (SSH uses them), - however, they are also less intuitive and more likely to cause you problems. -

3.1.6. enablePadding() and disablePadding()

- Enables / disables PKCS padding on block ciphers. Stream ciphers (Crypt_RC4 is the only stream - cipher currently included) ignore this. -

3.2. Crypt_DES

- Implements DES (a block cipher). Here's an example of how to use it: - 

<?php
-    include('Crypt/DES.php');
-
-    $des = new Crypt_DES();
-
-    $des->setKey('abcdefgh');
-
-    $size = 10 * 1024;
-    $plaintext = '';
-    for ($i = 0; $i < $size; $i++) {
-        $plaintext.= 'a';
-    }
-
-    echo $des->decrypt($des->encrypt($plaintext));
-?>

3.2.1. The constructor

- The constructor takes one optional parameter - $mode. $mode can be equal to CRYPT_DES_MODE_ECB - or CRYPT_DES_MODE_CBC. CRYPT_DES_MODE_CBC is generally considered more secure - and is what Crypt_DES uses by default. If you don't know the difference between ECB or CBC, - just use the default settings. -

3.3. Crypt_TripleDES

- Implements TripleDES (a block cipher). Here's an example of how to use it: - 

<?php
-    include('Crypt/TripleDES.php');
-
-    $des = new Crypt_TripleDES();
-
-    $des->setKey('abcdefghijklmnopqrstuvwx');
-
-    $size = 10 * 1024;
-    $plaintext = '';
-    for ($i = 0; $i < $size; $i++) {
-        $plaintext.= 'a';
-    }
-
-    echo $des->decrypt($des->encrypt($plaintext));
-?>

3.3.1. The constructor

- The constructor takes one optional parameter - $mode. $mode can be equal to CRYPT_DES_MODE_ECB, - CRYPT_DES_MODE_CBC, CRYPT_DES_MODE_3CBC, or CRYPT_DES_MODE_CBC3. - CRYPT_DES_MODE_CBC3 is an alias CRYPT_DES_MODE_CBC. It's defined to distinguish - it from CRYPT_DES_MODE_3CBC, which uses inner chaining to propogate the initialization vector. - SSH-1 uses this and it is generally considered to be less secure then CRYPT_DES_MODE_CBC3, - which uses outer chaining (and is what SSH-2 uses). -

3.4. Crypt_RC4

- Implements RC4 (a stream cipher). Here's an example of how to use it: - 

<?php
-    include('Crypt/RC4.php');
-
-    $rc4 = new Crypt_RC4();
-
-    $rc4->setKey('abcdefghijklmnopqrstuvwx');
-
-    $size = 10 * 1024;
-    $plaintext = '';
-    for ($i = 0; $i < $size; $i++) {
-        $plaintext.= 'a';
-    }
-
-    echo $rc4->decrypt($rc4->encrypt($plaintext));
-?>

3.4.1. The constructor

- Not much to say about this constructor. Since it's a stream cipher, you don't need to worry about which - mode of operation to use. -

3.5. Crypt_Rijndael & Crypt_AES

- Implements Rijndael / AES. Here's an example of how to use Crypt_AES: - 

<?php
-    include('Crypt/AES.php');
-
-    $aes = new Crypt_AES();
-
-    $aes->setKey('abcdefghijklmnop');
-
-    $size = 10 * 1024;
-    $plaintext = '';
-    for ($i = 0; $i < $size; $i++) {
-        $plaintext.= 'a';
-    }
-
-    echo $aes->decrypt($aes->encrypt($plaintext));
-?>

3.5.1. The constructor

- Crypt_AES's constructor takes CRYPT_AES_MODE_ECB and CRYPT_AES_MODE_CBC as parameters. Crypt_Rijndael, CRYPT_RIJNDAEL_MODE_ECB and CRYPT_RIJNDAEL_MODE_CBC. In both cases, if no valid mode is defined, CBC will be used. -

3.5.2. AES vs. Rijndael

- AES is a subset of Rijndael. Both have variable key sizes, however, AES's block size is fixed at 128 bytes, whereas Rijndael's is variable. Also, Rijndael supports, by means of an extension to the specification, two key sizes that AES does not - 160 bits and 224 bits. -

3.5.3. setKeyLength()

- Valid key lengths for AES are 128 bits, 192 bits, and 256 bits. If the key that is assigned is invalid and less than 256 bits, they key length is rounded up to the next closest valid size and the key will be null padded to that amount. If the key length is greater than 256 bits, it will be truncated to 256 bits. -

- As an example, if the key is 136 bits, it will be null padded to 192 bits (or 160 bits if Rijndael is being used). -

- If setKeyLength() has been called, this behavior changes somewhat. Say you've set the key length, via this function, to 256 bits. Then, instead of an invalid key being null padded to 192 or 160 bits, it will be null padded to 256 bits. -

3.5.4. setBlockLength()

- setBlockLength() operates in a manner similar to setKeyLength(), with one exception. setBlockLength() only works on Rijndael. Although Crypt_AES inherits setBlockLength() as a function, the function doesn't do anything in AES. -

3.5.5. Speed Comparisons

- The following table compares the speed of five different pure-PHP implementations of AES (one of which is Crypt_Rijndael and one of which is Crypt_AES) when ran on 150KB of text on a 1.8GHz Pentium 4-M. The numbers listed are averaged from five different trials and are measured in seconds. phpseclib's two implementations are highlighted. All implementations can be viewed by clicking on their names. -

Table 3.1. AES Speed Comparisons

movable-type.phpsphpaes.phpsphpclasses1.phpsphpclasses2.phpsphpseclib-aes.phpsphpseclib-rijndael.phps
15.684415817239.953724813515.010015010862.5917131900793.57283110815.24388728142

- As can be seen, phpseclib's implementations are the fastest. phpseclib-aes.phps is faster than phpseclib-rijndael.phps because phpseclib-rijndael.phps has to contend with multiple block sizes whereas phpseclib-aes.phps does not. -

1.2. Using phpseclib

1.1. Who should use phpseclib

- Although many of the features this library implements are implemented in PHP via optional extensions, what are - you, as a developer, going to do when a user tries to run your software on a host which, coincidentally, doesn't - happen to have that optional extension installed? You could, flat-out, tell that user to look for another - software package that does work on their server (or to get another host, or whatever), which is liable to leave - a bad impression on the user, or you could use a library like this - a library that uses those optional - extensions if they're available and falls back on an internal PHP implementation if they're not. -

- Another advantage of using this library over optional PHP extensions is that you, as a developer, may find this - libraries API easier to use then extensions API. -

1.2. Using phpseclib

- This library is written using the same conventions that libraries in the PHP Extension and Application Repository (PEAR) - have been written in. In particular, this library expects to be in your include_path: - 

<?php
-set_include_path(get_include_path() . PATH_SEPARATOR . 'phpseclib');
-
-include('Net/SSH2.php');
-?>

2.1. Math_BigInteger

- Implements an arbitrary precision integer arithmetic library. Uses gmp or bcmath, if available, and an - internal implementation, otherwise. Here's an example: - 

<?php
-    include('Math/BigInteger.php');
-
-    $a = new Math_BigInteger(2);
-    $b = new Math_BigInteger(3);
-
-    $c = $a->add($b);
-
-    echo $c->toString(); // outputs 5
-?>

2.1.1. Dependencies

- If you're running PHP 5, Math_BigInteger's only dependancy is the PCRE extension (which is enabled by default). Math_BigInteger also works on PHP 4 if PHP/Compat/Function/array_fill.php and PHP/Compat/Function/bcpowmod.php are included. -

2.1.2. The constructor

- The constructor takes two parameters. The first is the number and the second represents the base. Both - are optional (if they're not provided, the Math_BigInteger object will assume a value of 0). -

- The supported bases are base-2, base-10 (default), base-16, and base-256. To set $a, in the - above example, to 2, using base-2, we'd do new Math_BigInteger('10', 2). To do it using - base-16, you could do new Math_BigInteger('2', 16) or new Math_BigInteger('0x2', 16). - To set it to 2 using base-256, you'd do new Math_BigInteger(chr(2), 256). -

- If the base is negative (eg. -256), two's compliment will be used. Thus, new Math_BigInteger(chr(0xFF), -256) - is equal to -1, as is new Math_BigInteger('0xFFFFFFFF', -16) and new Math_BigInteger('11', -2). - Basically, if the leading bit is 1, the number is assumed to be negative. -

2.1.3. toString(), toBytes(), toHex() and toBits()

- toString() returns the base-10 form of a number. toBytes() returns the base-256 - form of a number, toHex() returns the base-16 form, and toBits() the base-2 form. - toBytes(), toHex(), and toBits() also take an optional parameter which, - if set, will return the two's compliment of a number. So if, for example, $a is equal to -1, - toBytes(true) will return chr(0xFF). -

- On PHP 5, toString() is called automatically when used in a string context via the - __toString() magic method. -

2.1.4. add(), subtract(), multiply() and divide()

- subtract() and multiply() operate similarly to add(). divide(), - however, does not. Namely, it returns an array whose first element contains the quotient and whose - second element contains the "common residue". If the remainder would be positive, the "common residue" - and the remainder are the same. If the remainder would be negative, the "common residue" is equal to - the sum of the remainder and the divisor (basically, the "common residue" is the first positive modulo). - Here's an example: - 

<?php
-    include('Math/BigInteger.php');
-
-    $a = new Math_BigInteger('10');
-    $b = new Math_BigInteger('20');
-
-    list($quotient, $remainder) = $a->divide($b);
-
-    echo $quotient->toString(); // outputs 0
-    echo "\r\n";
-    echo $remainder->toString(); // outputs 10
-?>

2.1.5. powMod() and modInverse()

- Examples of each follow: - 

<?php
-    include('Math/BigInteger.php');
-
-    $a = new Math_BigInteger('10');
-    $b = new Math_BigInteger('20');
-    $c = new Math_BigInteger('30');
-
-    $c = $a->powMod($b, $c);
-
-    echo $c->toString(); // outputs 10
-?>
<?php
-    include('Math/BigInteger.php');
-
-    $a = new Math_BigInteger(30);
-    $b = new Math_BigInteger(17);
-
-    $c = $a->modInverse($b);
-
-    echo $c->toString(); // outputs 4
-?>

2.1.6. gcd() and extendedGCD()

- extendedGCD() returns an array containing three Math_BigInteger values indexed with x, y, - and gcd. x and y represent Bézout's identity. gcd() returns a Math_BigInteger value - equal to the gcd. An example of each follows: - 

<?php
-include('Math/BigInteger.php');
-
-$a = new Math_BigInteger(693);
-$b = new Math_BigInteger(609);
-
-extract($a->extendedGCD($b));
-$c = $a->gcd($b);
-
-echo $gcd->toString() . "\r\n"; // outputs 21
-echo $c->toString() . "\r\n"; // outputs 21
-echo $a->toString() * $x->toString() + $b->toString() * $y->toString(); // outputs 21
-?>

2.1.7. abs()

- $x->abs() returns the absolute value of $x. -

2.1.8. equals() and compare()

- $x->equals($y) returns true or false depending on whether or not $x and - $y are equal. -

- $x->compare($y) returns 1 if $x > $y, 0 if $x == $y, and -1 if $x < $y. The reason for this - is demonstrated thusly: - 

$x  > $y: $x->compare($y)  > 0
-$x  < $y: $x->compare($y)  < 0
-$x == $y: $x->compare($y) == 0
-$x >= $y: $x->compare($y) >= 0
-$x <= $y: $x->compare($y) <= 0

- As a consequence of this, !$x->compare($y) does not mean $x != $y but rather - $x == $y. -

2.1.9. setPrecision()

- Some bitwise operations give different results depending on the precision being used. Examples include - left shift, not, and rotates, as discussed for bitwise_not(). - This function lets you control the precision. -

- Whenever a new Math_BigInteger object is created it's precision is set to the same precision as the - calling object. In other words, if you do $b = $a->bitwise_not() then $b will - have the same precision as $a. -

2.1.10. bitwise_and(), bitwise_or(), bitwise_xor() and bitwise_not()

- bitwise_and(), bitwise_or() and bitwise_xor() operate similar to - add(). bitwise_not() is a bit more complicated. To elaborate, if the - precision (see setPrecision) is arbitrary, - $x->bitwise_not() will always yield a smaller value since the most significant bit is - assumed to have a value of one. With fixed precision, however, the leading bit can be anything. -

2.1.11. bitwise_rightShift() and bitwise_leftShift()

- $a->bitwise_rightShift($shift) shifts $a by $shift bits, effectively dividing by 2**$shift. - $a->bitwise_leftShift($shift) shifts $a by $shift bits, effectively multiplying by 2**$shift. -

2.1.12. bitwise_rightRotate() and bitwise_leftRotate()

- $a->bitwise_rightRotate($shift) and $a->bitwise_leftRotate($shift) are - demonstrated thusly: - 

<?php
-include('Math/BigInteger.php');
-
-$a = new Math_BigInteger('00111000', 2);
-$a->setPrecision(8);
-$b = $a->bitwise_leftRotate(2);
-echo $b->toBits(); // returns 11100000
-
-echo "\r\n";
-
-$a = new Math_BigInteger('00111000', 2);
-$b = $a->bitwise_leftRotate(2);
-echo $b->toBits(); // returns 100011
-?>

- Just as with bitwise_not(), these operations are - precision dependant. -

2.1.13. setRandomGenerator()

- Sets the random generator. To set it to mt_rand() (which is what it is by default), call - $x->setRandomGenerator('mt_rand'). -

2.1.14. isPrime()

- Returns true if a number is prime and false if it isn't. -

2.1.15. random() and randomPrime()

- random($min, $max) generates a random number between $min and $max. - randomPrime($min, $max) generates a random prime number between $min and $max. - If no prime number exists between $min and $max false is returned. -

- randomPrime() has an optional third parameter, as well - $timeout. Generating prime numbers - is a particurarly expensive operation and although in certain environments even 512-bit primes can be - generated in a less than a second it can take other environments upwards of around a minute if not more. -

4.1. Crypt_Hash

4.1.1. Supported Algorithms and Dependencies

The following algorithms are supported:

md2, md5, md5-96, sha1, sha1-96, sha256, sha384, and sha512

- Crypt_Hash requires, minimally, PHP 4.3.0 (due to its use of - sha1()). If sha384 or sha512 are being used and - you're not running PHP 5.1.2 or greater then Math/BigInteger.php is also required. -

- Crypt_Hash uses the hash extension if it's available (> 5.1.2), mhash if it's not, and it's own - internal implementation if not even mhash is available. -

4.1.2. Example

<?php
-include('Crypt/Hash.php');
-
-$hash = new Crypt_Hash('sha1');
-//$hash->setKey('abcdefg');
-echo bin2hex($hash->hash('abcdefg'));
-?>

If $hash->setKey() had been called $hash->hash() would have returned an HMAC.

4.2. Crypt_RSA

4.2.1. Dependencies

- If you're running PHP 5, Crypt_RSA requires Math/BigInteger.php and Crypt/Hash.php. If you're running - PHP 4, Crypt_RSA also requires PHP/Compat/Function/array_fill.php, PHP/Compat/Function/bcpowmod.php, and - PHP/Compat/Function/str_split.php -

4.2.2. Examples

Here's an example of how to encrypt / decrypt with Crypt_RSA:

<?php
-include('Crypt/RSA.php');
-
-$rsa = new Crypt_RSA();
-extract($rsa->createKey());
-
-$plaintext = 'terrafrost';
-
-$rsa->loadKey($privatekey);
-$ciphertext = $rsa->encrypt($plaintext);
-
-$rsa->loadKey($publickey);
-echo $rsa->decrypt($ciphertext);
-?>

Here's an example of how to create / verify a signature with Crypt_RSA:

<?php
-include('Crypt/RSA.php');
-
-$rsa = new Crypt_RSA();
-extract($rsa->createKey());
-
-$plaintext = 'terrafrost';
-
-$rsa->loadKey($privatekey);
-$signature = $rsa->sign($plaintext);
-
-$rsa->loadKey($publickey);
-echo $rsa->verify($plaintext, $signature) ? 'verified' : 'unverified';
->

4.2.3. createKey()

- createKey() takes three parameters - $bits, $timeout, - and $primes. $timeout is present since creating a key has the potential to be - fairly time consuming and will guarantee that createKey() does not run for more than - $timeout seconds. $primes lets provide pre-computed prime numbers to speed - things up. -

- extract($rsa->createKey()) creates three variables - $publickey, - $privatekey, and $partialkey. If createKey hit the timeout then - it'll return all the primes that it had managed to compute so that you might pass them back to - createKey() on a subsequent call. -

- The exponent can be set by defining CRYPT_RSA_EXPONENT and multi-prime RSA can be utilized - by adjusting CRYPT_RSA_SMALLEST_PRIME. Note that these must be done before a Crypt_RSA() - object is initialized. -

- Smaller values for CRYPT_RSA_SMALLEST_PRIME result in increased speed at the cost of security. -

4.2.4. setPrivateKeyFormat(), setPublicKeyFormat(), loadKey() and setPassword()

Crypt_RSA supports the following formats:

-4QVCpLpf4FPO1j4ShHG5zwyUtdLg9R6i7B30iizYrRjn+w== phpseclib-generated-key

- Passwords can be set via setPassword() and are only supported on private keys. - CRYPT_RSA_PUBLIC_FORMAT_OPENSSH generates keys that are intended to go in $HOME/.ssh/authorized_keys - for use with OpenSSH. Another format - CRYPT_RSA_PUBLIC_FORMAT_RAW - is stored as an array with two - indexes - one for the modulus and one for the exponent. Indexes accepted by loadkey() - are as follows: -

- e, exponent, publicExponent, modulus, modulo, n -

- loadKey() has two parameters - $key and the optional $type. - The default type, if $type is not explicitely set, is CRYPT_RSA_PRIVATE_FORMAT_PKCS1. - It should, at this point, be noted that Crypt_RSA treats public and private keys largelly identically. - A key can be formatted as a CRYPT_RSA_PUBLIC_FORMAT_PKCS1 and still conform to the - CRYPT_RSA_PRIVATE_FORMAT_PKCS1 format and vice versa. The only real difference between private keys and - public keys is that private keys *can* contain their public key counterparts whereas public keys cannot. - That said, this distinction is, for the most part, irrelevant and academic. For a more thorough - discussion of this see setPublicKey() and getPublicKey(). -

4.2.5. setPublicKey() and getPublicKey()

- As noted in setPrivateKeyFormat(), setPublicKeyFormat(), loadKey() and setPassword(), - Crypt_RSA treats public and private keys largely identically. The only real difference is that some - private key formats contain the public key within them whereas no public key format does. The reason - you'd want to do this is for indexing purposes. For example, in SSH-2, RSA authentication works by - sending your public key along with a signature created by your private key. The SSH-2 server then looks - the public key up in an index of public keys to see if it's an allowed key and then verifies the signature. - To that end, setPublicKey() defines the public key if it hasn't already been defined and - getPublicKey() returns it. getPublicKey() has an optional parameter - $type - - that sets the format. -

4.2.6. encrypt(), decrypt() and setEncryptionMode()

- Crypt_RSA supports two encryption modes - CRYPT_RSA_ENCRYPTION_OAEP and - CRYPT_RSA_ENCRYPTION_PKCS1. CRYPT_RSA_ENCRYPTION_OAEP uses - Optimal Asymmetric Encryption Padding - and provides more security than CRYPT_RSA_ENCRYPTION_PKCS1. -

- Both CRYPT_RSA_ENCRYPTION_OAEP and CRYPT_RSA_ENCRYPTION_PKCS1 impose limits - on how large the plaintext can be. If the plaintext exceeds these limits the plaintext will be split - up such that each block falls within those limits. -

4.2.7. sign(), verify(), and setSignatureMode()

- Crypt_RSA supports two signature modes - CRYPT_RSA_SIGNATURE_PSS and - CRYPT_RSA_SIGNATURE_PKCS1. The former is assumed to provide more security than the latter. - See Examples for examples. -

4.2.8. setHash(), setMGFHash() and setSaltLength()

- In all likelihood, calling these functions will be unnecessary as the default values should be sufficient. - None-the-less a discussion of them follows. -

- setHash() is used with signature production / verification and (if the encryption mode is - CRYPT_RSA_ENCRYPTION_OAEP) encryption and decryption. If the specified hash isn't supported sha1 will - be used. -

- setMGFHash() determines which hashing function should be used for the mask generation - function as utilized in CRYPT_RSA_ENCRYPTION_OAEP and CRYPT_RSA_SIGNATURE_PSS. PKCS#1 recommends - but does not require that the MGFHash and the Hash be set to the same thing. -

- setSaltLength() is only utilized with CRYPT_RSA_SIGNATURE_PSS. PKCS#1 recommends this - value either be 0 (which is what it is by default) or the length of the output of the hash function as - set via setHash() -

5.1. Net_SSH

- The Net_SSH1 and Net_SSH2 libraries have, for the most part, an identical API. Some functions, however, do behave differently. -

5.1.1. Dependencies

- Net_SSH1/2 require, minimally, Math/BigInteger.php, Crypt/*.php, and PHP/Compat/Function/*.php. Net_SSH1 requires PHP 4.0.0 unless you're using the interactive functions, which require PHP 4.3.0. Net_SSH2 requires PHP 4.3.0 due to it's use of sha1(). -

5.1.2. Net_SSH1 Examples

<?php
-    include('Net/SSH1.php');
-
-    $ssh = new Net_SSH1('www.domain.tld');
-    if (!$ssh->login('username', 'password')) {
-        exit('Login Failed');
-    }
-
-    while (true) {
-        echo $ssh->interactiveRead();
-
-        $read = array(STDIN);
-        $write = $except = NULL;
-        if (stream_select($read, $write, $except, 0)) {
-            $ssh->interactiveWrite(fread(STDIN, 1));
-        }
-    }
-?>
<?php
-    include('Net/SSH1.php');
-
-    $ssh = new Net_SSH1('www.domain.tld');
-    if (!$ssh->login('username', 'password')) {
-        exit('Login Failed');
-    }
-
-    echo $ssh->exec('ls -la');
-?>

5.1.3. Net_SSH2 Examples

<?php
-    include('Net/SSH2.php');
-
-    $ssh = new Net_SSH2('www.domain.tld');
-    if (!$ssh->login('username', 'password')) {
-        exit('Login Failed');
-    }
-
-    echo $ssh->exec('pwd');
-    echo $ssh->exec('ls -la');
-?>
<?php
-    include('Crypt/RSA.php');
-    include('Net/SSH2.php');
-
-    $key = new Crypt_RSA();
-    //$key->setPassword('whatever');
-    $key->loadKey(file_get_contents('privatekey'));
-
-    $ssh = new Net_SSH2('www.domain.tld');
-    if (!$ssh->login('username', $key)) {
-        exit('Login Failed');
-    }
-
-    echo $ssh->exec('pwd');
-    echo $ssh->exec('ls -la');
-?<

5.1.4. Host Key Verification

- SSH protects itself against active eavesdroppers by providing a host key. The first time you connect the host key is supposed to be cached in some manner. On subsequent connections, the host key being used for this connection should be checked against the cached host key. If they match, it's the same server. If not, it's a different one. -

- In SSH-1, getHostKeyPublicModulus() and getHostKeyPublicExponent() will provide you with the host key. In SSH-2, getServerPublicHostKey() gets you the key. -

- The Net_SSH1 and Net_SSH2 examples omit the key verification stage for brevity. Also, depending on the context in which this library is used, it may even be unnecessary. For example, if you're connecting to www.example.com:22 from www.example.com:80, eavesdroppers are not something you need to worry about. -

5.1.5. interactiveRead() / interactiveWrite() vs. exec()

- Say you wanted to use SSH to get the contents of a directory. If you used interactiveWrite('ls') to do this, and then interactiveRead() to get the output, you, in all likelihood, wouldn't get the whole output. You'd have to call interactiveRead() multiple times - you'd have to call it as many times as it took for you to get the complete output, which, in turn, begs the question... how do you know when you have the complete output? - You could assume that whenever the prompt (eg. root@desktop:/root#) showed up, that that'd mean you had the complete output, but that's not fool proof. And what about messages of the day? The first interactiveRead() you do is liable to include a part of that rather than the directory listing. So, not only do you have to make some sort of guestimate as to when the output ends - you often may have to guestimate as to when it begins. -

- To top it all off, you may also get ANSI escape codes interspersed amongst the output, which would need to be removed. -

- Using exec('ls') resolves all of these issues. If you're implementing an interactive client, the interactive functions are the ones you'll want to use. Otherwise, exec() is likely what you'll want to use. -

- interactiveRead() / interactiveWrite() are not implemented in Net_SSH2. The SSH-2 protocol supports them, however, phpseclib does not. The reasons are discussed in the SSH-1's exec() vs. SSH-2's exec() section. -

5.1.6. SSH-1's exec() vs. SSH-2's exec()

- exec() works by creating a channel, issuing a command, and then subsequently destroying that channel. Since SSH-1 only allows one channel, exec() can only be called once. SSH-2, in contrast, allows an unlimited number of channels, and as such, you can perform as many exec()'s as you see fit. -

- As a consequence of this difference, Net_SSH2 does not implement interactiveRead() / interactiveWrite(), even though the SSH-2 specifications provide for those functions. Simply put, in SSH-1, those functions are necessary to do multiple commands. In SSH-2, they're not, and so they're not implemented. -

5.1.7. Successive calls to SSH-2's exec()

- Successive calls to SSH-2's exec() may not work as expected. Consider the following: - 

<?php
-    include('Net/SSH2.php');
-
-    $ssh = new Net_SSH2('www.domain.tld');
-    if (!$ssh->login('username', 'password')) {
-        exit('Login Failed');
-    }
-
-    echo $ssh->exec('pwd');
-    echo $ssh->exec('cd /');
-    echo $ssh->exec('pwd');
-?>

- If done on an interactive shell, the output you'd receive for the first pwd would (depending on how your system is setup) be different than the output of the second pwd. The above code snippet, however, will yield two identical lines. The reason for this is that any "state changes" you make to the one-time shell are gone once the exec() has been ran and the channel has been deleted. - As such, if you want to support cd in your program, it'd be best to just handle that internally and rewrite all commands, before they're passed to exec() such that the relative paths are expanded to the absolute paths. - Alternatively, one could always run a shell script, however, that may not always be an option. -

5.1.8. Debugging SSH-2

- To log output, the NET_SSH2_LOGGING constant will need to be defined. If you want full logs, you'll need to do define('NET_SSH2_LOGGING', NET_SSH2_LOG_COMPLEX). $ssh->getLog() will then return a string containing the unencrypted packets in hex and ASCII. If you want to just record the packet types that are being sent to and fro, you'll need to do define('NET_SSH2_LOGGING', NET_SSH2_LOG_SIMPLE). $ssh->getLog() will then return an array. Both log types include the amount of time it took to send the packet in question. The former is useful for general diagnostics and the latter is more useful for profiling. An example follows: - 

<?php
-    include('Net/SSH2.php');
-    define('NET_SSH2_LOGGING', NET_SSH2_LOG_COMPLEX);
-
-    $ssh = new Net_SSH2('www.domain.tld');
-    if (!$ssh->login('username', 'password')) {
-        exit('Login Failed');
-    }
-
-    echo $ssh->exec('pwd');
-    echo $ssh->getLog();
-?>

- Depending on the problem, it may be more effective to just look at the output of $ssh->getLastError() (which returns a string) and $ssh->getErrors() (which returns an array) than to sift through the logs. -

5.2. Net_SFTP

5.2.1. Introduction

- Net_SFTP currently only supports SFTPv3, which, according to wikipedia.org, "is the most widely used - version, implemented by the popular OpenSSH SFTP server". -

5.2.2. Dependencies

- Net_SFTP requires, minimally, PHP 4.3.0 and Net/SSH2.php, Math/BigInteger.php, Crypt/*.php, and PHP/Compat/Function/*.php. -

5.2.3. Net_SFTP Example

<?php
-include('Net/SFTP.php');
-
-$sftp = new Net_SFTP('www.domain.tld');
-if (!$sftp->login('username', 'password')) {
-    exit('Login Failed');
-}
-
-echo $sftp->pwd() . "\r\n";
-$sftp->put('filename.ext', 'hello, world!');
-print_r($sftp->nlist());
-?>

5.2.4. put($remote_file, $data [, $mode])

- By default, put() does not read from the local filesystem. $data is dumped directly into $remote_file. - So, for example, if you set $data to 'filename.ext' and then do get(), you will get a file, twelve bytes - long, containing 'filename.ext' as its contents. -

- Setting $mode to NET_SFTP_LOCAL_FILE will change the above behavior. With NET_SFTP_LOCAL_FILE, $remote_file will - contain as many bytes as filename.ext does on your local filesystem. If your filename.ext is 1MB then that is how - large $remote_file will be, as well. -

- Currently, only binary mode is supported. As such, if the line endings need to be adjusted, you will need to take - care of that, yourself. -

5.2.5. get($remote_file [, $local_file])

- Returns a string containing the contents of $remote_file if $local_file is left undefined or a boolean false if - the operation was unsuccessful. If $local_file is defined, returns true or false depending on the success of the - operation -

5.2.6. pwd(), chdir(), mkdir() and rmdir()

- pwd() returns the current directory, chdir() changes directories, mkdir() creates direcotires, and rmdir() removes directories. - In the event of failure, they all return false. chdir(), mkdir(), and rmdir() return true on successful completion of the operation. -

5.2.7. chmod() and size()

- chmod() sets the permissions on a file and returns the new file permissions on success or false on error. Permissions are expected to be in octal so to set a file to 777 do $sftp->chmod(0777, $filename) -

- size() returns the size, in bytes, of an arbitrary file. -

5.2.8. nlist() and rawlist()

- nlist($dir = '.') returns the contents of the current directory as a numerically indexed array and rawlist() returns an associate array where the filenames are the array keys and the array values are, themselves, arrays containing the file attributes. The directory can be changed with the first parameter. -

5.2.9. delete() and rename()

- The purpose of both functions should be easy enough to glean - delete() deletes files or directories and rename() renames them. Both return true on success and false on failure. -

5.2.10. Debugging SFTP

- Debbuging SFTP connections in phpseclib works in a manner similar to debugging SSH-2 Instead of the constant being NET_SSH2_LOGGING, however, it's NET_SFTP_LOGGING. And instead of NET_SSH2_LOG_COMPLEX or NET_SSH2_LOG_SIMPLE it's NET_SFTP_LOG_COMPLEX or NET_SFTP_LOG_SIMPLE respectively. And instead of calling $sftp->getLog() you call $sftp->getSFTPLog() or $sftp->getLastSFTPError() or whatever. -

3.1. Introduction

- All of the cryptographic libraries included in phpseclib use mcrypt, if available, and an internal implementation - if it's not. The libraries all use a common interface although some functions, for some algorithms, carry with - with them certain caveats. Those that do not have caveats attached (or have relatively few attached) are - described below. If you don't know which one to use, try Crypt_TripleDES. -

3.1.1. Dependencies

- The Crypt_* functions require, minimally, PHP 4.0.0. Crypt_TripleDES additionally requires Crypt/DES.php. -

3.1.2. setKey() and setIV()

- Sets the key and the initialization vector, respectively. If neither are set, each assumed to be equal to - some amount of null bytes. The initialization vector is only used in block ciphers and even then only - in CBC mode. If the key or the initialization vector are larger then the block size, they're truncated. - If they're smaller, they're padded with null bytes. -

3.1.3. encrypt() and decrypt()

- Self-explanatory. Encrypts or decrypts messages. See the examples in the subsequent sections. -

3.1.4. enableContinuousBuffer() and disableContinuousBuffer()

- If the continuous buffer is enabled and you're using a stream cipher or a block cipher mode other than ECB then encrypting the same string twice will yield different ciphertexts. - The reason being that the IV doesn't reset after each encryption / decryption round when the continuous buffer is used. - This provides better security but it may also make for less intuitive behavior. - For this reason, the continuous buffer is disabled by default. -

3.1.5. enablePadding() and disablePadding()

- Enables / disables PKCS padding on block ciphers. Stream ciphers (Crypt_RC4 is the only stream - cipher currently included) ignore this. -

3.1.6. A word of caution about stream ciphers and CTR mode

- Most stream ciphers (and block ciphers operating in a mode - like CTR - that turns them into stream ciphers) work by generating a stream of pseudorandom characters called a keystream and then XOR'ing that with the plaintext. - This *effectively* makes them one-time pads which, in theory, can provide perfect secrecy. The problem with one-time pads is that they're not as versatile as one might desire. - Among other things, a keystream must never be reset, lest it be possible for an attacker to recover the keystream via a known-plaintext attack. ie. $ciphertext ^ $plaintext = $key. If $key is constant (because the keystream's being reset or something) than an attacker can recover any $plaintext, but if not - if it's dynamic - then the only key that an attacker could recover is their own. -

3.2. Crypt_DES

- Implements DES (a block cipher). Here's an example of how to use it: - 

<?php
-    include('Crypt/DES.php');
-
-    $des = new Crypt_DES();
-
-    $des->setKey('abcdefgh');
-
-    $size = 10 * 1024;
-    $plaintext = '';
-    for ($i = 0; $i < $size; $i++) {
-        $plaintext.= 'a';
-    }
-
-    echo $des->decrypt($des->encrypt($plaintext));
-?>

3.2.1. The constructor

- The constructor takes one optional parameter - $mode. Valid values for $mode are as follows: -

  • CRYPT_DES_MODE_ECB
  • CRYPT_DES_MODE_CBC: The default value.
  • CRYPT_DES_MODE_CTR

3.3. Crypt_TripleDES

- Implements TripleDES (a block cipher). Here's an example of how to use it: - 

<?php
-    include('Crypt/TripleDES.php');
-
-    $des = new Crypt_TripleDES();
-
-    $des->setKey('abcdefghijklmnopqrstuvwx');
-
-    $size = 10 * 1024;
-    $plaintext = '';
-    for ($i = 0; $i < $size; $i++) {
-        $plaintext.= 'a';
-    }
-
-    echo $des->decrypt($des->encrypt($plaintext));
-?>

3.3.1. The constructor

- The constructor takes one optional parameter - $mode. Valid values for $mode are as follows: -

  • CRYPT_DES_MODE_ECB
  • CRYPT_DES_MODE_CBC3: Employs outer chaining to propogate the initialization vector. Used by SSH-2 and generally considered more secure than inner chaining.
  • CRYPT_DES_MODE_3CBC: Employs inner chaining to propogate the initialization vector. Used by SSH-1.
  • CRYPT_DES_MODE_CBC: The default value. An alias for CRYPT_DES_MODE_CBC3.
  • CRYPT_DES_MODE_CTR

3.4. Crypt_RC4

- Implements RC4 (a stream cipher). Here's an example of how to use it: - 

<?php
-    include('Crypt/RC4.php');
-
-    $rc4 = new Crypt_RC4();
-
-    $rc4->setKey('abcdefghijklmnopqrstuvwx');
-
-    $size = 10 * 1024;
-    $plaintext = '';
-    for ($i = 0; $i < $size; $i++) {
-        $plaintext.= 'a';
-    }
-
-    echo $rc4->decrypt($rc4->encrypt($plaintext));
-?>

3.4.1. The constructor

- Not much to say about this constructor. Since it's a stream cipher, you don't need to worry about which - mode of operation to use. -

3.5. Crypt_Rijndael & Crypt_AES

- Implements Rijndael / AES. Here's an example of how to use Crypt_AES: - 

<?php
-    include('Crypt/AES.php');
-
-    $aes = new Crypt_AES();
-
-    $aes->setKey('abcdefghijklmnop');
-
-    $size = 10 * 1024;
-    $plaintext = '';
-    for ($i = 0; $i < $size; $i++) {
-        $plaintext.= 'a';
-    }
-
-    echo $aes->decrypt($aes->encrypt($plaintext));
-?>

3.5.1. The constructor

- Crypt_AES's constructor's optional parameter can take the following values: -

  • CRYPT_AES_MODE_ECB
  • CRYPT_AES_MODE_CBC: The default value.
  • CRYPT_AES_MODE_CTR

- Crypt_Rijndael takes the following: -

  • CRYPT_RIJNDAEL_MODE_ECB
  • CRYPT_RIJNDAEL_MODE_CBC: The default value.
  • CRYPT_RIJNDAEL_MODE_CTR

3.5.2. AES vs. Rijndael

- AES is a subset of Rijndael. Both have variable key sizes, however, AES's block size is fixed at 128 bits, whereas Rijndael's is variable. Also, Rijndael supports, by means of an extension to the specification, two key sizes that AES does not - 160 bits and 224 bits. -

3.5.3. setKeyLength()

- Valid key lengths for AES are 128 bits, 192 bits, and 256 bits. If the key that is assigned is invalid and less than 256 bits, they key length is rounded up to the next closest valid size and the key will be null padded to that amount. If the key length is greater than 256 bits, it will be truncated to 256 bits. -

- As an example, if the key is 136 bits, it will be null padded to 192 bits (or 160 bits if Rijndael is being used). -

- If setKeyLength() has been called, this behavior changes somewhat. Say you've set the key length, via this function, to 256 bits. Then, instead of an invalid key being null padded to 192 or 160 bits, it will be null padded to 256 bits. -

3.5.4. setBlockLength()

- setBlockLength() operates in a manner similar to setKeyLength(), with one exception. setBlockLength() only works on Rijndael. Although Crypt_AES inherits setBlockLength() as a function, the function doesn't do anything in AES. -

3.5.5. Speed Comparisons

- The following table compares the speed of five different pure-PHP implementations of AES (one of which is Crypt_Rijndael and one of which is Crypt_AES) when ran on 150KB of text on a 1.8GHz Pentium 4-M. The numbers listed are averaged from five different trials and are measured in seconds. phpseclib's two implementations are highlighted. All implementations can be viewed by clicking on their names. -

Table 3.1. AES Speed Comparisons

movable-type.phpsphpaes.phpsphpclasses1.phpsphpclasses2.phpsphpseclib-aes.phpsphpseclib-rijndael.phps
15.684415817239.953724813515.010015010862.5917131900792.035815429687522.62501101493836

- As can be seen, phpseclib's implementations are the fastest. phpseclib-aes.phps is faster than phpseclib-rijndael.phps because phpseclib-rijndael.phps has to contend with multiple block sizes whereas phpseclib-aes.phps does not. Note that if mcrypt weren't explicitily disabled phpseclib would have been even faster. -
