     6    The base64sha256 function computes the SHA256 hash of a given string and
     7    encodes it with Base64.

    10  # `base64sha256` Function
    11  
    12  `base64sha256` computes the SHA256 hash of a given string and encodes it with
    13  Base64. This is not equivalent to `base64encode(sha256("test"))` since `sha256()`
    14  returns hexadecimal representation. 
    15  
    16  The given string is first encoded as UTF-8 and then the SHA256 algorithm is applied
    17  as defined in [RFC 4634](https://tools.ietf.org/html/rfc4634). The raw hash is
    18  then encoded with Base64 before returning. Terraform uses the "standard" Base64
    19  alphabet as defined in [RFC 4648 section 4](https://tools.ietf.org/html/rfc4648#section-4).

    30  * [`filebase64sha256`](./filebase64sha256.html) calculates the same hash from
    31    the contents of a file rather than from a string value.
    32  * [`sha256`](./sha256.html) calculates the same hash but returns the result
    33    in a more-verbose hexadecimal encoding.
