base64sha512 Function

base64sha512 computes the SHA512 hash of a given string and encodes it with Base64. This is not equivalent to base64encode(sha512("test")) since sha512() returns hexadecimal representation.

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 with Base64 before returning. OpenTF uses the "standard" Base64 alphabet as defined in RFC 4648 section 4.

Examples​

> base64sha512("hello world")

  • filebase64sha512 calculates the same hash from the contents of a file rather than from a string value.
  • sha512 calculates the same hash but returns the result in a more-verbose hexadecimal encoding.
