NAME

       Dancer::Session::Cookie - Encrypted cookie-based session backend for Dancer

VERSION

       version 0.22

SYNOPSIS

       Your config.yml:

           session: "cookie"
           session_cookie_key: "this random key IS NOT very random"

DESCRIPTION

       This module implements a session engine for sessions stored entirely in cookies. Usually
       only session id is stored in cookies and the session data itself is saved in some external
       storage, e.g.  database. This module allows one to avoid using external storage at all.

       Since server cannot trust any data returned by client in cookies, this module uses
       cryptography to ensure integrity and also secrecy. The data your application stores in
       sessions is completely protected from both tampering and analysis on the client-side.

CONFIGURATION

       The setting session should be set to "cookie" in order to use this session engine in a
       Dancer application. See Dancer::Config.

       A mandatory setting is needed as well: session_cookie_key, which should contain a random
       string of at least 16 characters (shorter keys are not cryptographically strong using AES
       in CBC mode).

       Here is an example configuration to use in your config.yml:

           session: "cookie"
           session_cookie_key: "kjsdf07234hjf0sdkflj12*&(@*jk"

       Compromising session_cookie_key will disclose session data to clients and proxies or
       eavesdroppers and will also allow tampering, for example session theft. So, your
       config.yml should be kept at least as secure as your database passwords or even more.

       Also, changing session_cookie_key will have an effect of immediate invalidation of all
       sessions issued with the old value of key.

       session_cookie_path can be used to control the path of the session cookie.  The default is
       /.

       The global session_secure setting is honoured and a secure (https only) cookie will be
       used if set.

DEPENDENCY

       This module depends on Session::Storage::Secure.  Legacy support is provided using
       Crypt::CBC, Crypt::Rijndael, String::CRC32, Storable and MIME::Base64.

SEE ALSO

       See Dancer::Session for details about session usage in route handlers.

       See Plack::Middleware::Session::Cookie, Catalyst::Plugin::CookiedSession, "session" in
       Mojolicious::Controller for alternative implementation of this mechanism.
