    10  # `sha512` Function
    11  
    12  `sha512` computes the SHA512 hash of a given string and encodes it with
    13  hexadecimal digits.
    14  
    15  The given string is first encoded as UTF-8 and then the SHA512 algorithm is applied
    16  as defined in [RFC 4634](https://tools.ietf.org/html/rfc4634). The raw hash is
    17  then encoded to lowercase hexadecimal digits before returning.

    19  ## Examples
    20  
    21  ```
    22  > sha512("hello world")

    28  * [`filesha512`](./filesha512.html) calculates the same hash from
    29    the contents of a file rather than from a string value.
    30  * [`base64sha512`](./base64sha512.html) calculates the same hash but returns
    31    the result in a more-compact Base64 encoding.
