In ed6ebb696e (sm: Implement initial support for keyboxd., 2020-09-10),
the return of keydb_search() was changed to use gpg_err_code(). Adjust
gpgsm_verify() to use it. This provides a nicer error message to users
when a certificate is not found -- the same error that is seen from 2.2.
Prior to this change, when a cert was not found, gpgsm output:
gpgsm: failed to find the certificate: Not found
as opposed to the more human-readable message from 2.2:
gpgsm: certificate not found
They now return the same message.

When creating a signature or encrypting and the respective key is not

than the standard buffer size (which is currently 8k). If is not a
complete solution but the best we can do easily. Outputting to the

I did some test against
Governikus_Signer: 2.9.2.0
MCard security Provider: 2.4.0
Algorithm catalog from: 05.12.2019
using a Signature Card v2.0 and a nistp256 certificate. Encrypting
with Governikus used the stdDH-sha1kdf scheme which we can now
decrypt. Encrypting with GPGSM uses for that curve the recommended
scheme sha256kdf but Governikus was not able to decrypt this (no
usable error message). Encrypting using stdDH-sha1kdf with GPGSM by
using the new --debug-force-ecdh-sha1kdf option showed that
Governikus was able to decrypt this.

the id-aes128-cbc content encryption algorithm; and
which Governikus seems not to fulfill.

Note that we now use the full fingerprint instead of the certificate
id. This better aligns with what we do in gpg.
