Or just wait untl it switches to OpenSSL? Good question. Sequoia has a flexible mechanism to describe its cryptographic policy: https://docs.sequoia-pgp.org/sequoia_openpgp/policy/struct.StandardPolicy.html There isn't yet a way to configure it using a configuration file, but that is doable. Here's the issue, fwiw: https://gitlab.com/sequoia-pgp/sequoia/-/issues/857 One potential issue is that OpenPGP fingerprints are computed using SHA-1. In practice this is not a security problem as fingerprints don't need collision resistance, just second pre-image resistance, which SHA-1 still has. The upcoming version of the OpenPGP specification specifies SHA2 256-based fingerprints https://datatracker.ietf.org/doc/html/draft-ietf-openpgp-crypto-refresh-06#section-5.5.4 But we won't be able to switch immediately: users would have to create new certificates, and old certificates would have to fall out of use.
