# ID sets up a basic framework for implementing an id based sessioning
# service. Cookies sent to the client for maintaining sessions will only
# contain an id reference. Only #find_session, #write_session and
# #delete_session are required to be overwritten.
#
# All parameters are optional.
# * :key determines the name of the cookie, by default it is
#   'rack.session'
# * :path, :domain, :expire_after, :secure, :httponly, and :same_site set
#   the related cookie options as by Rack::Response#set_cookie
# * :skip will not a set a cookie in the response nor update the session state
# * :defer will not set a cookie in the response but still update the session
#   state if it is used with a backend
# * :renew (implementation dependent) will prompt the generation of a new
#   session id, and migration of data to be referenced at the new id. If
#   :defer is set, it will be overridden and the cookie will be set.
# * :sidbits sets the number of bits in length that a generated session
#   id will be.
#
# These options can be set on a per request basis, at the location of
# <tt>env['rack.session.options']</tt>. Additionally the id of the
# session can be found within the options hash at the key :id. It is
# highly not recommended to change its value.

Rack::Session::Abstract::SessionHash::Unspecified = T.let(T.unsafe(nil), Object)

# Rack::Session::Cookie provides simple cookie based session management.
# By default, the session is a Ruby Hash that is serialized and encoded as
# a cookie set to :key (default: rack.session).
#
# This middleware accepts a :secrets option which enables encryption of
# session cookies. This option should be one or more random "secret keys"
# that are each at least 64 bytes in length. Multiple secret keys can be
# supplied in an Array, which is useful when rotating secrets.
#
# Several options are also accepted that are passed to Rack::Session::Encryptor.
# These options include:
# * :serialize_json
#     Use JSON for message serialization instead of Marshal. This can be
#     viewed as a security enhancement.
# * :gzip_over
#     For message data over this many bytes, compress it with the deflate
#     algorithm.
#
# Refer to Rack::Session::Encryptor for more details on these options.
#
# Prior to version TODO, the session hash was stored as base64 encoded
# marshalled data. When a :secret option was supplied, the integrity of the
# encoded data was protected with HMAC-SHA1. This functionality is still
# supported using a set of a legacy options.
#
# Lastly, a :coder option is also accepted. When used, both encryption and
# the legacy HMAC will be skipped. This option could create security issues
# in your application!
#
# Example:
#
#   use Rack::Session::Cookie, {
#     key: 'rack.session',
#     domain: 'foo.com',
#     path: '/',
#     expire_after: 2592000,
#     secrets: 'a randomly generated, raw binary string 64 bytes in size',
#   }
#
# Example using legacy HMAC options:
#
#   Rack::Session:Cookie.new(application, {
#     # The secret used for legacy HMAC cookies, this enables the functionality
#     legacy_hmac_secret: 'legacy secret',
#     # legacy_hmac_coder will default to Rack::Session::Cookie::Base64::Marshal
#     legacy_hmac_coder: Rack::Session::Cookie::Identity.new,
#     # legacy_hmac will default to OpenSSL::Digest::SHA1
#     legacy_hmac: OpenSSL::Digest::SHA256
#   })
#
#
#   Rack::Session::Cookie.new(application, {
#     :coder => Rack::Session::Cookie::Identity.new
#   })
