Jiapeng Chong	20508b751b	crypto: sig - Remove some unused functions ... These functions are defined in the sig.c file, but not called elsewhere, so delete these unused functions. crypto/sig.c:24:34: warning: unused function '__crypto_sig_tfm'. Reported-by: Abaci Robot <abaci@linux.alibaba.com> Closes: https://bugzilla.openanolis.cn/show_bug.cgi?id=5701 Signed-off-by: Jiapeng Chong <jiapeng.chong@linux.alibaba.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>	2023-07-20 22:15:12 +12:00
Herbert Xu	891ebfdfa3	crypto: sig - Fix verify call ... The dst SG list needs to be set to NULL for verify calls. Do this as otherwise the underlying algorithm may fail. Furthermore the digest needs to be copied just like the source.

Herbert Xu	6cb8815f41	crypto: sig - Add interface for sign/verify ... Split out the sign/verify functionality from the existing akcipher interface. Most algorithms in akcipher either support encryption and decryption, or signing and verify. Only one supports both. As a signature algorithm may not support encryption at all, these two should be spearated. For now sig is simply a wrapper around akcipher as all algorithms remain unchanged. This is a first step and allows users to start allocating sig instead of akcipher. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>	2023-06-23 16:15:36 +08:00
