We are making a federated end-to-end encrypted messaging protocol and implementation.

I understand the importance of getting any security-related software audited by qualified cryptographers. Most other secure messengers have got an audit. However there is no business invovled here, just me and 2 friends involved in making it (and mostly just me), and I don’t view forking over a ton of money for this as a reasonable option.

I found the Open Crypto Audit project which sounds like exactly what I’m looking for, but I don’t think they exist anymore, their website and twitter account haven’t been updated since 2015. I contacted them anyway just incase but haven’t got a response.

Any other options?
