Obtaining a DES License or a 3DES-AES License

---

The Cisco ASA 5550 adaptive security appliance is available either with a DES or 3DES-ASE license that provides encryption technology to enable specific features, such as secure remote management (SSH, ASDM, and so on), site-to-site VPN, and remote access VPN. The license is enabled through an encryption license key.

If you ordered your adaptive security appliance with a DES or 3DES-AES license, the encryption license key comes with the adaptive security appliance.

If you are a registered user of Cisco.com and would like to obtain a 3DES/AES encryption license, go to the following website:

Note You will receive the new activation key for your adaptive security appliance within two hours of requesting the license upgrade.

For more information on activation key examples or upgrading software, see the Cisco Security Appliance Command Line Configuration Guide.

To use the activation key, perform the following steps:

	Command	Purpose
Step 1	hostname# show version	Shows the software release, hardware configuration, license key, and related uptime data.
Step 2	hostname# configure terminal	Enters global configuration mode.
Step 3	hostname(config)# activation-key activation-5-tuple-key	Updates the encryption activation key by replacing the activation-4-tuple-key variable with the activation key obtained with your new license. The activation-5-tuple-key variable is a five-element hexadecimal string with one space between each element. An example is 0xe02888da 0x4ba7bed6 0xf1c123ae 0xffd8624e. The "0x" is optional; all values are assumed to be hexadecimal.
Step 4	hostname(config)# exit	Exits global configuration mode.
Step 5	hostname# copy running-config startup-config	Saves the configuration.
Step 6	hostname# reload	Reboots the adaptive security appliance and reloads the configuration.
