It's always exciting when you're working on a really complicated project and you get to the first working demo. Even if it only does something simple, it's still a thrill. OpenMLS can now use Bitcoin & Nostr cryptography. LFG.

What does it mean that openmls uses bitcoin and nostr cryptography? Do you mean like it now supports the same ciphersuites?
Yes, it now supports the same ciphersuites. The MLS spec doesn't specifically mention the secp256k1 curve or schnorr signatures but does leave open the idea of "private" ciphersuites. My changes added a private identifier for schnorr signatures over secp256k1 and then I added support to the main library via their default crypto library RustCrypto and I also created a new library to use the secp256k1 library instead of RustCrypto (secp256k1 is the library that all Bitcoin and most nostr projects already use).
