HSM support

HSM encryption support for passwords

Airlock IAM REST API supports HSM (hardware security modules) with a PKCS #11 interface for the following use cases:

  • Encrypt password hashes before storing them in the user database.
  • Password end-to-end encryption.
 
Info

The instructions have been tested with SoftHSM and SafeNet Luna, but should work with any compatible PKCS#11 token.

Prerequisites

For this guide, the following assumptions are made:

  • A Hardware Security Module (HSM) is deployed on the network
  • The required key material is provisioned on the HSM. Use the HSM interface to manage the keys.
    • For end-to-end encryption: The HSM has to provide the appropriate key (usually a certificate containing an RSA key) for the alias configured in IAM.
    • For the encrypted hash function feature: The HSM has to provide the appropriate secret key entry (e.g. an AES key) for the alias and key type configured in IAM.
  • A connection is established between the system running Airlock IAM and the HSM.
  • The PKCS #11 native extensions of the HSM are installed on the system running Airlock IAM.
  • TCP keep-alive should be enabled on both the HSM and the client.

  • If the connection is killed on either side, the Sun PKCS #11 Provider will throw an exception with “java.security.ProviderException: Token has been removed”.
