Problem:
|
|
* jabber password should not be stored on server
|
|
* jabber password should not be sent between server and browser as soon as the user is logged in
|
|
* jabber password should not be reconstructible from communication between server and browser as soon as the user is logged in
|
|
|
|
Solution:
|
|
Only store an encrypted version of the jabber password on the server. The encryption key is only available to the browser
|
|
and not to the server (at least as soon as the user is logged in). It can be stored using the jappix setDB function.
|
|
|
|
This encryption key could be the friendica password, but then this password would be stored in the browser in cleartext.
|
|
It is better to use a hash of the password.
|
|
The server should not be able to reconstruct the password, so we can't take the same hash the server stores. But we can
|
|
use hash("some_prefix"+password). This will however not work with OpenID logins, for this type of login the password must
|
|
be queried manually.
|
|
|
|
Problem:
|
|
How to discover the jabber addresses of the friendica contacts?
|
|
|
|
Solution:
|
|
Each Friendica site with this addon provides a /jappixmini/ module page. We go through our contacts and retrieve
|
|
this information every week using a cron hook.
|
|
|
|
Problem:
|
|
We do not want to make the jabber address public.
|
|
|
|
Solution:
|
|
When two friendica users connect using DFRN, the relation gets a DFRN ID and a keypair is generated.
|
|
Using this keypair, we can provide the jabber address only to contacts:
|
|
|
|
Alice:
|
|
signed_address = openssl_*_encrypt(alice_jabber_address)
|
|
send signed_address to Bob, who does
|
|
trusted_address = openssl_*_decrypt(signed_address)
|
|
save trusted_address
|
|
encrypted_address = openssl_*_encrypt(bob_jabber_address)
|
|
reply with encrypted_address to Alice, who does
|
|
decrypted_address = openssl_*_decrypt(encrypted_address)
|
|
save decrypted_address
|
|
|
|
Interface for this:
|
|
GET /jappixmini/?role=%s&signed_address=%s&dfrn_id=%s
|
|
|
|
Response:
|
|
json({"status":"ok", "encrypted_address":"%s"})
