new(secret, sign_secret = nil, cipher: nil, digest: nil, serializer: nil)
public

Initialize a new MessageEncryptor. secret must be at least as long as the cipher key size. For the default ‘aes-256-gcm’ cipher, this is 256 bits. If you are using a user-entered secret, you can generate a suitable key by using ActiveSupport::KeyGenerator or a similar key derivation function.

First additional parameter is used as the signature key for MessageVerifier. This allows you to specify keys to encrypt and sign data.

ActiveSupport::MessageEncryptor.new('secret', 'signature_secret')

Options:

  • :cipher - Cipher to use. Can be any cipher returned by OpenSSL::Cipher.ciphers. Default is ‘aes-256-gcm’.

  • :digest - String of digest to use for signing. Default is SHA1. Ignored when using an AEAD cipher like ‘aes-256-gcm’.

  • :serializer - Object serializer to use. Default is Marshal.
