[CryptoKeyPurpose][google.cloud.kms.v1.CryptoKey.CryptoKeyPurpose] describes the cryptographic capabilities of a
[CryptoKey][google.cloud.kms.v1.CryptoKey]. A given key can only be used for the operations allowed by
its purpose. For more information, see
Key purposes.
[CryptoKeys][google.cloud.kms.v1.CryptoKey] with this purpose may be used with
[AsymmetricDecrypt][google.cloud.kms.v1.KeyManagementService.AsymmetricDecrypt] and
[GetPublicKey][google.cloud.kms.v1.KeyManagementService.GetPublicKey].
AsymmetricSign
[CryptoKeys][google.cloud.kms.v1.CryptoKey] with this purpose may be used with
[AsymmetricSign][google.cloud.kms.v1.KeyManagementService.AsymmetricSign] and
[GetPublicKey][google.cloud.kms.v1.KeyManagementService.GetPublicKey].
EncryptDecrypt
[CryptoKeys][google.cloud.kms.v1.CryptoKey] with this purpose may be used with
[Encrypt][google.cloud.kms.v1.KeyManagementService.Encrypt] and
[Decrypt][google.cloud.kms.v1.KeyManagementService.Decrypt].
Mac
[CryptoKeys][google.cloud.kms.v1.CryptoKey] with this purpose may be used with
[MacSign][google.cloud.kms.v1.KeyManagementService.MacSign].
