Import OTR key and fingerprints from Pidgin

[micahflee]

This is a feature request. It would be great the Gajim plugin configure window could have an "Import From Pidgin" button next to "Generate". It would see if these files exist:

~/.purple/otr.private_key
~/.purple/otr.fingerprints

If they do, it would load these, parse them, and convert the keys to Gajim .key3 and .fpr formats.

I wrote a script that converts Pidgin OTR keys to Gajim OTR keys: https://github.com/micahflee/pidgin2gajim

If you want to implement this feature, maybe this code will save you some time.

FYI, I'm pretty busy right now. Will work on this in a few weeks time.

Thank you!

FYI, we have an otrfileconverter project aiming to convert between all otr formats+apps. It mostly works, but is somewhat raw. Needs some usability polish before we publish it as a standalone tool.

If you're interested, we could rework the module API a bit so it could be integrated into an app as a library.

Hey Abel! Actually, I copied a bunch of code from otrfileconverter to make pidgin2gajim (https://github.com/micahflee/pidgin2gajim/blob/master/pidgin2gajim.py#L9). I think making it a library would be awesome, so that any OTR client can easily offer an import feature.

I think it makes more sense to support key format conversion/importing outside of the IM apps. OTR File Converter handles format conversion, file syncing on the local system, and soon sync with Gibberbot over the network via OTR.

That said, I think a lot of the primitives for handling the different key formats should be pushed upstream as much as possible, and not in otrfileconverter. It currently uses a bunch of different python crypto libraries in order to support all of the required formats (x509, PKCS#8, etc.)
