ECC Crypto for S/MIME key generation and usage should be implemented.
Original report:
Hello
I would like create a X.509 Key with ECDSA option to specify a max validity date.
But the option is anavailable (grey).
Why? (A software parameter is wrong?)
How to do ?
Thanks for your answer

There is currently no ECC key support in the S/MIME component of Gpg4win. I've edited the task a bit to reflect that. So it is impossible to generate an ECC Key for S/MIME with Kleopatra.
It should definitely be implemented but this is no small task :-/
There are two code paths to generate key: gpgsm_genkey and gpgsm_gencertreq_tty. Latter is partially supported with card key.
Firstly, I'm going to work for T4888.
I am working on the Telesec Signature Card v2. I will add encryption support to gpgsm.
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.
Signing using ECDSA does now also work. Tested with 3 in disk keys: nistp256, nistp384 and RSA and verified using gpgsm and Governikus Signer.
GnuTLS seems to have some CMS support; see https://gitlab.com/gnutls/gnutls/-/issues/227 .
