sha512 Function

sha512 computes the SHA512 hash of a given string and encodes it with hexadecimal digits.

The given string is first encoded as UTF-8 and then the SHA512 algorithm is applied as defined in RFC 4634. The raw hash is then encoded to lowercase hexadecimal digits before returning.

Examples

> sha512("hello world")
