project.
ext/digest:
This module provides the module Digest and the abstract class
Digest::Base.
ext/digest/md5 (which obsoletes ext/md5):
This module provides the class Digest::MD5 which implements the
MD5 Message-Digest Algorithm.
ext/digest/rmd160:
This module provides the class Digest::RMD160 which implements the
RIPEMD-160 cryptographic hash function.
ext/digest/sha1 (which obsoletes ext/sha1):
This module provides the class Digest::SHA1 which implements the
SHA-1 Secure Hash Algorithm.
ext/digest/sha2:
This module provides the classes Digest::SHA256, Digest::SHA384
and Digest::SHA512 which implement the SHA-256, SHA-384 and
SHA-512 Secure Hash Algorithms, respectively.
lib/md5.rb, lib/sha1.rb:
These files are provided for backward compatibility.
All these classes have the common API, which previously ext/md5 and
ext/sha1 modules provided. While the new API keeps 100% backward
compatibility, it has been enriched with several utility methods.
Read digest.txt for further details.

Independent implementation of MD5 (RFC 1321).

This code implements the MD5 Algorithm defined in RFC 1321.

It is derived directly from the text of the RFC and not from the

reference implementation.

1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
|
