Draft: Use gnutls instead of gcrypt

Vivien Kraus Would Rather Not Be On Gitlab.com requested to merge vivien_/guile-goblins:main into main

Hi! Gnutls recently got support for the cryptography API goblin needs, so the gcrypt dependency is not needed anymore. There is still something that is not released: the base16 encoding, however it is being worked on.

This proof-of-concept merge request shows how to use gnutls instead of gcrypt. The most important change is now EDDSA signatures are a single bytevector, instead of a pair of components. Is it a problem?

Also, I’m not sure what should be the sexp format to send the public key and signature on the wire (through syrup). I think this is incompatible right now.

I checked locally that the tests pass, but unfortunately my runner can’t seem to work properly:

Is it a known issue?

Best regards,

Vivien
