tm_sha256 Function

tm_sha256 computes the SHA256 hash of a given string and encodes it with hexadecimal digits.

The given string is first encoded as UTF-8 and then the SHA256 algorithm is applied as defined in RFC 4634. The raw hash is then encoded to lowercase hexadecimal digits before returning.


tm_sha256("hello world")
  • tm_filesha256 calculates the same hash from the contents of a file rather than from a string value.
  • tm_base64sha256 calculates the same hash but returns the result in a more-compact Base64 encoding.
