[OTR-users] SILC + OTR & Deniability?

[Jason Cohen]

SILC provides encryption/authentication in user & channel chats, as well
as encrypted file transfers. I would like to use OTR with SILC as SILC's
private key exchange for user chats requires a direct peer to peer
connection and therefore doesn't work when both users are behind a NAT
firewall, and I was wondering if this would still retain the deniability
aspect of OTR. I made sure to turn off digital signing of of SILC IMs.
The session key is generated using Diffie Hellman Key Exchange and is
signed with the sender's public key. However, the messages themselves
are not signed but a MAC is used to provide integrity.
