sha512 package:SHA

For those for whom only the biggest hashes will do, this computes the SHA-512 hash of the given ByteString. The output will be 64 bytes, or 512 bits, long.
Similar to sha512 but use an incremental interface. When the decoder has been completely fed, completeSha512Incremental must be used so it can finish successfully.
Compute an HMAC using SHA-512.
