Import the "digest" module and the submodules, from the Rough Ruby
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.
