Install

Gem

To install this gem in your shell or terminal:

gem install sixarm_ruby_password_salt

Gemfile

To add this gem to your Gemfile:

gem 'sixarm_ruby_password_salt'

Require

To require the gem in your code:

require 'sixarm_ruby_password_salt'

Example

Generate a salt:

require 'sixarm_ruby_password_salt'
PasswordSalt.new => "ezkabtsu"

This generates a secure random 8 character salt of all lowercase letters with 26^8 combinations. This can easily be sent via web URIs, email, etc.

SecureRandom

Ruby 1.8.6 and older does not have a secure random number method, so this gem checks to see if the SecureRandom class is defined; if it is not, then we require our sixarm_ruby_secure_random gem.
