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