// Keys are defined in pairs to allow key rotation, but the common case is
// to set a single authentication key and optionally an encryption key.
//
// The first key in a pair is used for authentication and the second for
// encryption. The encryption key can be set to nil or omitted in the last
// pair, but the authentication key is required in all pairs.
//
// It is recommended to use an authentication key with 32 or 64 bytes.
// The encryption key, if set, must be either 16, 24, or 32 bytes to select
// AES-128, AES-192, or AES-256 modes.
//
// Use the convenience function securecookie.GenerateRandomKey() to create
// strong keys.
