# SecurityInfoKeys

The security keys that Answer Server uses to encrypt and decrypt the security information that it uses for user security.

To use AES encryption (recommended), set `SecurityInfoKeys` to the file name and path of the AES key file. Answer Server then uses this key file to encrypt and decrypt the `SecurityInfo` tokens. For information about how to create a key file, refer to the IDOL Server Administration Guide.

For older systems that use TEA encryption, set `SecurityInfoKeys` to four signed 32-bit integers (between `0` and `2147483647`), separated with commas. There must be no space before or after the commas.

NOTE: You must set `SecurityInfoKeys` to the same value that you use for all other components that use an AES key file or four-number security identifier.
