WebC++, Perl, Ruby and other programming languages have their own security APIs created as part of the standard library or as supplementary modules. A message digest hash function is a cryptographic primitive used for digital signatures and password protection. It maps a message of arbitrary length to a fixed-length hash value or "message digest".

A hash function takes in an input and returns a fixed-size output. In a cryptographic hash function, the output is typically represented as a hexadecimal string. It’s important to note that a hash function is not meant to be reversed, it’s a one-way function. This is what makes it great for storing passwords.

A hash function can be considered to be a fingerprint of the file or message. See Hash function.

WebTo compute the hash, OAuth1.0a says you need to first alphabetize the fields, separate them by newlines, remove the field names (which are well known), and use blank lines for empty values. The signature or hash is computed on the result of that canonicalization. XML DSIG works the same way - you need to canonicalize the XML before signing it.
