| Encrypt | This strategy allows you to encrypt your `Session` and / or `Cookie` data so that it is not stored in cleartext on the client side. You must provide a secret key, otherwise an exception is raised. |
| Hmac | This strategy allows you to sign your `Session` and / or `Cookie` data with a passphrase to ensure that it has not been tampered with. |
| MissingSignatureException | A `MissingSignatureException` may be thrown when reading data from a session-based storage that is expecting an HMAC signature, but none is found. |
