Hashit

Wrapper for Ruby's hashing functions

Installation

Add this line to your application's Gemfile:

gem 'hashit'

And then execute:

$ bundle

Or install it yourself as:

$ gem install hashit

Usage

Hashit supports the following hashing algorithms

md2
md4
md5
sha
sha1
sha224
sha256
sha384
sha512

For each of these there is the standard method and a timed method. Both accept a key and some text to hash, but the timed version will create a hash that is only valid for a certain amount of time

Example

hash = Hashit.sha256("key", "some text")
timed_hash = Hashit.timed_sha256("key", "some text")

You can then validate those hashes using matches?:

if Hashit.matches?(hash, "key", "some text")
  # The data matches the hash
end

In the case of the timed hash you may want to check if it previously matched the data. In such a case you can use the did_match? function:

if Hashit.matches?(timed_hash, "key", "some text")
  # The data matches the current timed hash
elsif Hashit.did_match?(timed_hash, "key", "some text")
  # The data matched the previous timed hash
end
