Overview

A CryptoKeyVersion represents an individual cryptographic key, and the associated key material.

An ENABLED version can be used for cryptographic operations.

For security reasons, the raw cryptographic key material represented by a CryptoKeyVersion can never be viewed or exported. It can only be used to encrypt, decrypt, or sign data when an authorized user or application invokes Cloud KMS.

Defined Under Namespace

Modules: CryptoKeyVersionAlgorithm, CryptoKeyVersionState, CryptoKeyVersionView
