Description

digest/hmac.rb

An implementation of HMAC keyed-hashing algorithm

Overview

This library adds a method named hmac() to Digest classes, which creates a Digest class for calculating HMAC digests.

Examples

require 'digest/hmac'

# one-liner example
puts Digest::HMAC.hexdigest("data", "hash key", Digest::SHA1)

# rather longer one
hmac = Digest::HMAC.new("foo", Digest::RMD160)

buf = ""
while stream.read(16384, buf)
  hmac.update(buf)
end

puts hmac.bubblebabble
