linux-stable.git/include/crypto/sig.h, branch linux-6.5.y Linux kernel stable tree crypto: sig - Add interface for sign/verify 2023-06-23T08:15:36+00:00 Herbert Xu herbert@gondor.apana.org.au 2023-06-15T10:28:48+00:00 6cb8815f41a966b217c0d9826c592254d72dcc31 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> 
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.
