[OTR-dev] RSA signatures again

[Timo Sirainen]

I was planning to use libotr for a project where I'd need both "normal" asymmetric encryption (RSA probably) and OTR-like encryption. The problem is that I was hoping to use a single public key for both uses, but OTR uses only DSA and I can't do encryption with it. My next thought was to modify libotr to support RSA signatures as well, but since I'm not really a crypto expert I thought I'd ask here first if that's even a good idea? Would it be as simple as changing the DSA-specific code to RSA or are there some deeper problems to solve as well?
