Overview

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..."
