* 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..."
