dm-encrypted

A DataMapper type that supports RSA encrypted columns.

Installation

gem install qhoxie-rcrypt qhoxie-dm-encrypted --source http://gems.github.com

Private and public key constants need to be set:

PRIVATE_KEY = "-----BEGIN RSA PRIVATE KEY-----\nMIIEpgI..."
PUBLIC_KEY = "-----BEGIN RSA PUBLIC KEY-----\nXLPBCgK..."

In your models, you simply specify the column type as Encrypted:

class Account
  include DataMapper::Resource

  property :id,         Serial
  property :username,   String
  property :password,   Encrypted
end

Saving and loading those fields will transparently work with plaintext:

>> Account.create :username => "me", :password => "secret"
>> Account.first.password
=> "secret"

However it is ciphertext in the database:

>> select password from accounts;
=> qxZjz37mt2PU...tcHPf5Un3RGAyxaT==
