# HMACValidation

DEPRECATED: The `HMACValidation` parameter is deprecated for IDOL Server version 12.9.0 and later.

In version 12.9.0, the AES implementation for encrypting security info strings was updated to include built-in authentication, so additional HMAC validation is no longer required or supported.

The `HMACValidation` parameter still exists, but it no longer has any effect. The parameter might be deleted in future.

Set `HMACValidation` to `True` to enable HMAC when you use AES encryption.

NOTE: To use this option, you must have Content 10.1.0 or later, and you must set this configuration parameter in the Content and Community configuration files.

Type: | Boolean
Default: | False
Required: | No
Configuration Section: | Security
Example: | `HMACValidation=True`
