GpgSM: Add ECC support (Option to create an X.509/ECDSA key)
Open, HighPublic


ECC Crypto for S/MIME key generation and usage should be implemented.

Original report:

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 :-/

Thanks for your answer

Best regards

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.
