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
or you could set
ENV['STRING_ENCRYPTION_KEY'] = "somekey"
where "somekey" is your key in environment.rb.
Now encryption/decryption is easy.
"Test".encrypt #=> "NDFkZTc5NDEyNTg1MzdiZPzBrxZz5aoN%0A"
"NDFkZTc5NDEyNTg1MzdiZPzBrxZz5aoN%0A".decrypt #=> "Test"
