New update 0.2.4 is available:
https://openrepos.net/content/chrm/cryptmee

Some bugfixes in PGP/MIME parsing.
Private keypair handling:
- settings option for additional encryption with own key
- now able to delete private key pairs from device.

Still no idea how to get encrypted message part from IM (XMPP, ...)
Is here anyone who can build current telepathy/gabble packages for Harmattan? They seems to support OTR now.
