This commit supports displaying the OIDs for unknown signature and public key algorithms. The output also showsthe bytes of the public key. This can be used for example to examine certificates with PQC algorithms.

Shouldn't (0 unknown) now indicate something like ML-DSA-44? Do these need regeneration?

Maybe needs a split in logic between an actually unknown algorithms, and the ones that you added in this PR, as the latter ones are not unknown algorithms (anymore).

What do you mean? Now, unless the certificate parsing fails, I can extract at least the OID of the public key and signature algorithms, instead of just crashing.

The main thing was that the algorithms extracted using the new method aren't (fully) unknown (anymore), as they're now known in this library, but maybe it's a bit too pedantic. On the other hand: it is performing logic for the case it's the x509.UnknownPublicKeyAlgorithm, so maybe not that bad.

Description
This commit supports displaying the OIDs for unknown signature and public key algorithms. The output also shows the bytes of the public key.
This can be used for example to examine certificates with PQC algorithms.
An example of this is:
