crypto: sm2 - Fix crash caused by uninitialized context

2023-09-20T05:10:10+00:00

In sm2_compute_z_digest() function, the newly allocated structure mpi_ec_ctx is used, but forget to initialize it, which will cause a crash when performing subsequent operations.

KEYS: asymmetric: Move sm2 code into x509_public_key

2023-06-23T08:15:37+00:00

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 - make dependent on sm3 library

2022-01-28T05:51:10+00:00

SM3 generic library is stand-alone implementation, it is necessary for the calculation of sm2 z digest to depends on SM3 library instead of sm3-generic. Signed-off-by: Tianjia Zhang Signed-off-by: Herbert Xu

crypto: sm2 - fix a memory leak in sm2

2021-06-11T07:03:30+00:00

SM2 module alloc ec->Q in sm2_set_pub_key(), when doing alg test in test_akcipher_one(), it will set public key for every test vector, and don't free ec->Q. This will cause a memory leak. This patch alloc ec->Q in sm2_ec_ctx_init().

crypto: sm2 - remove unnecessary reset operations

2020-10-30T06:35:02+00:00

This is an algorithm optimization. The reset operation when setting the public key is repeated and redundant, so remove it. At the same time, `sm2_ecc_os2ec()` is optimized to make the function more simpler and more in line with the Linux code style. Signed-off-by: Tianjia Zhang Signed-off-by: Herbert Xu
