* Document-class: Digest::MD5 < Digest::Base
* A class for calculating message digests using the MD5
* Message-Digest Algorithm by RSA Data Security, Inc., described in
* RFC1321.
*
* MD5 calculates a digest of 128 bits (16 bytes).
*
* == Examples
* require 'digest'
*
* # Compute a complete digest
* Digest::MD5.hexdigest 'abc' #=> "90015098..."
*
* # Compute digest by chunks
* md5 = Digest::MD5.new # =>#<Digest::MD5>
* md5.update "ab"
* md5 << "c" # alias for #update
* md5.hexdigest # => "90015098..."
*
* # Use the same object to compute another digest
* md5.reset
* md5 << "message"
* md5.hexdigest # => "78e73102..."
