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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@1609 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
