Package sha512 implements the SHA-384, SHA-512, SHA-512/224, and SHA-512/256 cryptographic hash functions.
BlockSize is the block size, in bytes, of the SHA-512/224, SHA-512/256, SHA-384 and SHA-512 hash functions.
The size of a SHA512 checksum in bytes.
Block adds a new SHA-512 block to the state.
Sum512 returns the SHA512 checksum of the data.
