NAME
CGI::Session::ID::sha - CGI::Session ID driver for generating SHA-1 based IDs
SYNOPSIS
use CGI::Session; $session = new CGI::Session('id:sha', undef);
DESCRIPTION
Use this module to generate SHA-1 encoded hexadecimal IDs for CGI::Session objects. This library does not require any arguments. To use it, add id:sha to the DSN string when creating CGI::Session objects.
Keep in mind
Keep in mind that a SHA-1 encoded hexadecimal string will have 40 characters. Don't forget to take this into account when using a database to store your session. For example, when using the default table layout with MySQL you'd want to create a table like:
CREATE TABLE sessions ( id CHAR(40) NOT NULL PRIMARY KEY, a_session NOT NULL, );
CAVEATS
There are no caveats with this module, but rather with the way CGI::Session loads this module:
