# SecurityInfoKeys

The security keys that Distributed Action Handler 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. Distributed Action Handler 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, including the child IDOL Servers. DAH uses these keys to decrypt and resolve database mapping.

In cases where you use a DAH in an IDOL Server unified configuration, and you use the user security encryption keys, you must configure `SecurityInfoKeys` in both the `[Security]` and `[DistributionSettings]` sections of the IDOL Server configuration file.
