6 Optional Maintenance and Upgrade Procedures
Obtaining DES and 3DES/AES Encryption Licenses
The adaptive security appliance offers the option to purchase a DES or 3DES-AES license to enable
specific features that provide encryption technology, such as secure remote management (SSH, ASDM,
and so on), site-to-site VPN, and remote access VPN. Enabling the license requires 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 did not order your adaptive security appliance with a DES or 3DES-AES license and would like
to purchase one now, the encryption licenses are available at no charge on
Cisco.com.
