It is possible to use a hardware security module (HSM) or a smart card to store the decryption keys required for decrypting audit trails. An HSM or a smart card is a tamper-resistant physical, software, or cloud solution that can securely store digital keys used for authentication.

The main steps of configuring a hardware security module (HSM) or smart card to integrate with an external indexer are as follows:

  1. Set up and test the environment.

  2. Encrypt the PKCS#11 PIN.

To see examples of how to configure various HSM or smart card solutions that you wish to integrate with your external indexer(s), consult the following sections:
