SHA512Hash()
SHA-512 hashing. The SHA-256 and SHA-512 functions are provided for interoperability with other applications. If you are looking for a generic hash function and not specifically SHA-2, using crypto_generichash() (BLAKE2b) might be a better choice.
These functions are also not suitable for hashing passwords or deriving keys from passwords. Use one of the password hashing APIs instead.
These functions are not keyed and are thus deterministic. In addition, the untruncated versions are vulnerable to length extension attacks.
