plug_rails_cookie_session_store v1.0.0 API Reference
Modules
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
