What is Cisco ASA 5540 V8.2 (1) Keymaker V1.0?
Cisco ASA 5540 V8.2 (1) Keymaker V1.0 is a software tool that was released in September 2009 by a group called SSG. It is designed to generate a valid license key for the SecurityPlus feature set of the Cisco ASA 5540 firewall running on version 8.2 (1) of the software.
The SecurityPlus feature set is an optional upgrade that adds more security capabilities to the Cisco ASA 5540 firewall, such as:
Support for up to 10 virtual firewalls (contexts)
Support for up to 25 SSL VPN peers
Support for up to 5000 IPSec VPN peers
Support for Active/Active and Active/Standby failover modes
Support for transparent firewall mode
Support for IPv6 and multicast traffic
To enable the SecurityPlus feature set, you need to purchase a license from Cisco and activate it on your firewall. However, Cisco ASA 5540 V8.2 (1) Keymaker V1.0 allows you to bypass this process and generate a license key for free.
How does Cisco ASA 5540 V8.2 (1) Keymaker V1.0 work?
Cisco ASA 5540 V8.2 (1) Keymaker V1.0 works by exploiting a vulnerability in the license activation mechanism of the Cisco ASA 5540 firewall running on version 8.2 (1) of the software. The vulnerability allows an attacker to generate a valid license key using a serial number of any Cisco ASA 5540 firewall.
The tool requires two inputs: the serial number of your Cisco ASA 5540 firewall and the activation key of any other Cisco ASA 5540 firewall with SecurityPlus enabled. The tool then uses an algorithm to combine these inputs and produce a new activation key that matches your serial number and enables SecurityPlus on your firewall.
The tool is available as an executable file that can be run on Windows or Linux platforms. It has a simple graphical user interface that allows you to enter the inputs and generate the output.
How to use Cisco ASA 5540 V8.2 (1) Keymaker V1.0?
To use Cisco ASA 5540 V8.2 (1) Keymaker V1.0, you need to follow these steps:
Download the tool from a reliable source and save it on your computer.
Run the tool and enter the serial number of your Cisco ASA 5540 firewall in the Serial Number field.
Enter the activation key of any other Cisco ASA 5540 firewall with SecurityPlus enabled in the Activation Key field.
Click on Generate button and wait for the tool to produce a new activation key in the Output field.
Copy the new activation key and paste it on your Cisco ASA 5540 firewall using the command line interface or the web interface.
Verify that SecurityPlus is enabled on your firewall by checking the show version command output or the web interface.

Alternatives to Cisco ASA 5540 V8.2 (1) Keymaker V1.0
While Cisco ASA 5540 V8.2 (1) Keymaker V1.0 may seem like an attractive option to enable SecurityPlus on your firewall for free, it is not the only way to do so. There are some alternatives that you can consider, such as:

You can buy a license from Cisco or an authorized reseller and get the activation key and instructions to apply it on your firewall. This way, you can enjoy the full support and updates from Cisco and avoid any potential risks or issues associated with using an unauthorized tool.
Using a different firewall model or version: If you have a different firewall model or version that supports SecurityPlus without a license, you can use that instead of Cisco ASA 5540 V8.2 (1). For example, you can use Cisco ASA 5510 or 5520 with SecurityPlus preinstalled, or Cisco ASA 5505 with SecurityPlus enabled by default.
Using a different security solution: If you do not need SecurityPlus or you are not satisfied with its features, you can use a different security solution that meets your needs and budget. For example, you can use a different firewall vendor or product, or a cloud-based security service.
