- Class:
ActionDispatch::Cookies::ChainedCookieJars
encrypted()public
Returns a jar that’ll automatically encrypt cookie values before sending them to the client and will decrypt them for read. If the cookie was tampered with by the user (or a 3rd party), nil will be returned.
If config.action_dispatch.encrypted_cookie_salt and config.action_dispatch.encrypted_signed_cookie_salt are both set, legacy cookies encrypted with HMAC AES-256-CBC will be transparently upgraded.
This jar requires that you set a suitable secret for the verification on your app’s secret_key_base.
Example:
cookies.encrypted[:discount] = 45 # => Set-Cookie: discount=DIQ7fw==--K3n//8vvnSbGq9dA--7Xh91HfLpwzbj1czhBiwOg==; path=/ cookies.encrypted[:discount] # => 45
