crypto: sm2 - Remove sm2 algorithm

2024-06-07T11:46:39Z

The SM2 algorithm has a single user in the kernel. However, it's never been integrated properly with that user: asymmetric_keys. The crux of the issue is that the way it computes its digest with sm3 does not fit into the architecture of asymmetric_keys. As no solution has been proposed, remove this algorithm. It can be resubmitted when it is integrated properly into the asymmetric_keys subsystem. Signed-off-by: Herbert Xu

crypto: sm2 - Provide sm2_compute_z_digest when sm2 is disabled

2023-06-26T08:14:01Z

When sm2 is disabled we need to provide an implementation of sm2_compute_z_digest. Fixes: e5221fa6a355 ("KEYS: asymmetric: Move sm2 code into x509_public_key") Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202306231917.utO12sx8-lkp@intel.com/ Signed-off-by: Herbert Xu

KEYS: asymmetric: Move sm2 code into x509_public_key

2023-06-23T08:15:37Z

The sm2 certificate requires a modified digest. Move the code for the hashing from the signature verification path into the code where we generate the digest. Signed-off-by: Herbert Xu

crypto: sm2 - introduce OSCCA SM2 asymmetric cipher algorithm
