# `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](https://tools.ietf.org/html/rfc4634). The raw hash is
then encoded to lowercase hexadecimal digits before returning.

## Examples

```
> sha512("hello world")

```
