Password hash tool to create secure passwords,

This uses SHA256 hexdigest for the cryptographic hash, and authenticates a password, salt, and hash.

To create a password:

require 'sixarm_ruby_password_hash'
text = 'mysecret'
salt = 'azsxdcfv'
hash = PasswordHash.new(text,salt)

To create a password using our helpers:

require 'sixarm_ruby_password_hash'
require 'sixarm_ruby_password_salt'
require 'sixarm_ruby_password_text'
text = PasswordText.new
salt = PasswordSalt.new
hash = PasswordHash.new(text,salt)

To verify a password:

hash.valid?(text,salt)

To verify a password from a web form for a user:

user = User.find(params[:id]) or raise 'user not found'
user.hash.valid?(params[:password],user.salt)
