Mechanism description
The PKCS#1 DSA signature with SHA-1 mechanism, denoted CKM_DSA_SHA1_PKCS, performs single and multiple-part digital signature and verification operations without message recovery. The operations performed are as described in PKCS#1 with the object identifier sha1WithDSAEncryption.
It is similar to the PKCS#11 mechanism CKM_RSA_SHA1_PKCS except DSA is used instead of RSA. This mechanism has no parameter.
