Encrypting and decrypting data is not exactly the most straightforward and DRY way. encrypted_strings improves the syntax and reduces the complexity, adding straightforward support for encrypting values using SHA-1, Symmetric, and Asymmetric ciphers.

>> password = 'shhhh'
=> "shhhh"
>> encrypted_password = password.encrypt
=> "66c85d26dadde7e1db27e15a0776c921e27143bd"
>> encrypted_password.class
=> String
>> encrypted_password.cipher
=> #<EncryptedStrings::ShaCipher:0x2b9238889460 @salt="salt">
>> encrypted_password == 'shhhh'
=> true
>> encrypted_password.decrypt
NotImplementedError: Decryption is not supported using a(n) EncryptedStrings::ShaCipher

When encrypt is called, it creates a cipher instance which is used for future encryption and decryption of the string. The default cipher uses SHA-1 encryption. For ciphers that do not support decryption, equality with other strings is tested by encrypting the other string and checking whether the resulting encrypted value is the same.

>> password = 'shhhh'
=> "shhhh"
>> crypted_password = password.encrypt(:symmetric, :password => 'secret_key')

>> crypted_password == 'shhhh'
=> true
>> password = crypted_password.decrypt
=> "shhhh"

>> password = 'shhhh'
=> "shhhh"
>> crypted_password = password.encrypt(:asymmetric, :public_key_file => './public.key', :private_key_file => './private.key')

None.
