OpenKCM

Open Key Chain Manager (OpenKCM) is a data-encryption key management solution implementing a hierarchical key derivation system, including a customer-managed-key (CMK) layer that gives customers control over the master key. Plugin APIs are defined in Protocol Buffers, and the project includes a KMIP client library. Software; Apache 2.0.

OpenKCM is key management for a cloud that wants customers to hold their own keys. It is part of NeoNephos, a Linux Foundation Europe project.

  • Customer-managed keys - The CMK service carries the application logic for customer control of the master key.
