From the TrueNAS Documentation Hub: TrueNAS is the world’s most popular Open Source storage operating system and is the most efficient solution for managing and sharing data over a network. It is the simplest way to create a safe, secure, centralized, and easily accessible place for your data. TrueNAS Open Storage provides unified ZFS-based storage for file, block, object, and application data.

What is KMIP?

The Key Management Interoperability Protocol (KMIP) is an extensible communication protocol that defines message formats for the manipulation of cryptographic keys on a key management server. This facilitates data encryption by simplifying encryption key management. You can create keys on a server and then retrieve them, possibly wrapped by other keys. KMIP supports both symmetric and asymmetric keys and the ability to sign certificates. KMIP also enables clients to ask a server to encrypt or decrypt data without needing direct access to the key.

​
Integration purpose

KMIP on TrueNAS Enterprise integrates the system within an existing centralized key management infrastructure and uses a single trusted source (such as the KMES Series 3) for creating, using, and destroying Self Encrypting Drive (SED) passwords and Z File System (ZFS) encryption keys.
