Ruby on Rails Plugin: string_encryption

This is a very simple Ruby on Rails plugin that allows easy encryption of strings. For the sake of simplicity there no customization. The only cipher used is 'des-ede3-cbc' (Triple DES using Cipher Block Chaining) . See my post on encrypting/decrypting a string with Ruby for more information. First install the plugin:


script/plugin install git://github.com/handerson/string_encryption.git

Next we need to add an encryption key as the constant @ENV['STRING_ENCRYPTION_KEY']@. To do this just run


script/generate encryption_key

or you could set 


ENV['STRING_ENCRYPTION_KEY'] = "somekey"

where "somekey" is your key in environment.rb.

Now encryption/decryption is easy.

Encryption:


"Test".encrypt  #=> "NDFkZTc5NDEyNTg1MzdiZPzBrxZz5aoN%0A"

Decryption:


"NDFkZTc5NDEyNTg1MzdiZPzBrxZz5aoN%0A".decrypt  #=> "Test"
