annotate sat/plugins/plugin_sec_otr.py @ 2743:da59ff099b32
core (memory/encryption), plugin OTR: finished OTR integration in encryption:
- messageEncryptionStart and messageEncryptionStop are now async
- an encryption plugin can now have a startEncryption and endEncryption method, which are called automatically when suitable
- trust is now put in "trusted" key of message_data, and markAsTrusted has been added, it is used in OTR
- getTrustUI implemented for OTR, using legacy authenticate code
- catch potr.crypt.InvalidParameterError on decryption
- fixed some service OTR messages which were not correctly marked as not for storing, and thus were added to MAM archive/carbon copied
- other bug fixes
