The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The article describes the process of upgrading a license from a single to triple data encryption standard/advanced encryption standard (3DES/AES) for Adaptive Security Appliance (ASA). A 3DES/AES license, otherwise known as a K9 license, is required for strong encryption. If you do not have a K9 license, decryption processing with a server that requires strong encryption fails. Any flow that requires decryption that the device cannot perform is denied regardless of access policies. Although the K9 license is free, its availability is limited by export restrictions.
