golang.org/x/crypto/openpgp is deprecated

[johanfleury]

Hey, just wanted to share that golang.org/x/crypto/openpgp is deprecated (see golang/go#44226 for details).

There are a few forks, mainly:

• https://github.com/ProtonMail/go-crypto (which seems to be the most active/used)
• and https://github.com/keybase/go-crypto

Migrating to one of these projects doesn’t seem too hard as they are forks of the original go-crypto repository.

BTW, I think (but I can’t be sure) that ProtonMail’s fork supports Ed25519, which mean it would be possible to verify commit signed with that key type.

Currently, commit.Verify returns this error openpgp: unsupported feature: public key type: 22.

I tested while making #283 and can confirm that Ed25519 keys are supported.
