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:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e

-** MD5(Class)
-A class to implement MD5 Message-Digest Algorithm by RSA Data
-Security, Inc., described in RFC1321.
-Superclass: Object
-Class Methods:
- new([str])
- md5([str])
- Creates a new MD5 object. If a string argument is given, it
- is added to the object. (see update.)
- clone
- Copies the MD5 object.
- digest
- Returns the MD5 hash of the added strings as a string of 16
- bytes.
- hexdigest
- Returns the MD5 hash of the added strings as a string of 32
- hexadecimal digits. This method is equal to:
- def hexdigest
- ret = ''
- digest.each_byte {|i| ret << sprintf('%02x', i) }
- ret
- end
- update(str)
- << str
- Update the MD5 object with the string str. Repeated calls are
- equivalent to a single call with the concatenation of all the
- arguments, i.e. m.update(a); m.update(b) is equivalent to
- m.update(a+b) and m << a << b is equivalent to m << a+b.
-Local variables:
