core, memory, bridge: added profile password + password encryption:
/!\ This changeset updates the database version to 2 and modify the database content!
Description:
- new parameter General / Password to store the profile password
- profile password is initialized with XMPP password value, it is stored hashed
- bridge methods asyncCreateProfile/asyncConnect takes a new argument "password" (default = "")
- bridge method asyncConnect returns a boolean (True = connection already established, False = connection initiated)
- profile password is checked before initializing the XMPP connection
- new private individual parameter to store the personal encryption key of each profile
- personal key is randomly generated and encrypted with the profile password
- personal key is decrypted after profile authentification and stored in a Sessions instance
- personal key is used to encrypt/decrypt other passwords when they need to be retrieved/modified
- modifying the profile password re-encrypt the personal key
- Memory.setParam now returns a Deferred (the bridge method "setParam" is unchanged)
- Memory.asyncGetParamA eventually decrypts the password, Memory.getParamA would fail on a password parameter
TODO:
- if profile authentication is OK but XMPP authentication is KO, prompt the user for another XMPP password
- fix the method "registerNewAccount" (and move it to a plugin)
- remove bridge method "connect", sole "asyncConnect" should be used
