ArEncrypt
===========
This is a plugin to make fields easily encrypt-able. It works much like the serialize method.
Encryption is done before save using Digest::SHA1.hexdigest()
Example
=======
# class User < ActiveRecord::Base
#
# attr_accessor :confirm_password
#
# validate :password_match
# encrypt :password
# encrypt :ssn
# encrypt :confirm_password
#
#
# def password_match
# errors.add(:password, "confirmation must match.") if self.password_changed? && (self.password != self.confirm_password)
# end
#
# end
you can also redefine the encryption method by overriding the encrypt method of the ArEncrypt module
# module ArEncrypt
# def self.encrypt(string)
# Digest::SHA1.hexdigest(string).to_s
# end
# end
to check for a match you just call the attribute that is encrypted with _match? on the end
example:
u = User.first
u.password_match?('correctpassword')
to find a user with a matching ssn
User.ssn_find('123456789')
to find all users with a matching ssn
User.ssn_find_all('123456789')
added an option of finds to extend the search for unencrypted parameters
to find all users with a matching ssn and name
User.ssn_find_all('123456789', :name=>'john')
