SHA-512 digest

The SHA-512 mechanism, denoted CKM_SHA512, is a mechanism for message digesting, following the Secure Hash Algorithm with a 512-bit message digest defined in FIPS PUB 180-2.

It does not have a parameter.

Constraints on the length of input and output data are summarized in the following table. For single-part digesting, the data and the digest may begin at the same location in memory.
