The CRL states how long it is valid and we cache it for about that time.
OCSP responses are by definition not cachable but we allow for a clock skew of 10 minutes.

Its a year since I worked on the mentioned wait code change (wk/new-wait branch) and I more or less forgot about it. it will to risky to release that as 1.14 so this change and the fix to this bug needs to be postponed to 1.15. Sorry.

This appears to still be a problem, despite upgrading to libksba 1.4.0:

GnuTLS seems to have some CMS support; see https://gitlab.com/gnutls/gnutls/-/issues/227 .

Seems to be fixed now.

Parsing and creating of certs does now work. I was not able to find sample CMS objects so this part is not yet finished.

Finished if an existing key is used. See rG6dc3846d78192e393be73c16c72750734a9174d1 for examples.

See rG6dc3846d78192e393be73c16c72750734a9174d1 for examples on how to create a cert

Signing using ECDSA does now also work. Tested with 3 in disk keys: nistp256, nistp384 and RSA and verified using gpgsm and Governikus Signer.

Basic en- and decryption test against Governikus_Signer has now been done. Beware: I had to add a debug option to gpgsm to workaround non-compliance in algorithm support of Governikus; see the rG68b857df13c8a4e6cae5e3a29fd065bf90764547 for details.

It works for me(tm).
