Stores the session in a cookie

MessageEncryptor is a simple way to encrypt values which get stored somewhere you don’t trust. The cipher text and initialization vector are base64 encoded and returned to you. This can be used in situations similar to the MessageVerifier, but where you don’t want users to be able to determine the value of the payload.

Example

secret_key_base = "072d1e0157c008193fe48a670cce031faa4e..."
encrypted_cookie_salt = "encrypted cookie"
encrypted_signed_cookie_salt = "signed encrypted cookie"
secret = KeyGenerator.generate(secret_key_base, encrypted_cookie_salt)
sign_secret = KeyGenerator.generate(secret_key_base, encrypted_signed_cookie_salt)
encryptor = MessageEncryptor.new(secret, sign_secret)
data = %{current_user: %{name: "José"}}
encrypted = MessageEncryptor.encrypt_and_sign(encryptor, data)
decrypted = MessageEncryptor.verify_and_decrypt(encryptor, encrypted)
decrypted.current_user.name # => "José"

MessageVerifier makes it easy to generate and verify messages which are signed to prevent tampering. For example, the cookie store uses this verifier to send data to the client. Although the data can be read by the client, he cannot tamper it
