--kms-resource="gcp-kms://projects/<project>/locations/<region>/keyRings/<key-ring>/cryptoKeys/<key>" \
--output="enc-keyset.cfg"
You can also create a GCP KMS encrypted Tink keyset with tinkey:
tinkey create-keyset --key-template ECDSA_P384 --out enc-keyset.cfg --master-key-uri gcp-kms://projects/<project>/locations/<region>/keyRings/<key-ring>/cryptoKeys/<key>
You must have the permissions to read the KMS key, and create a certificate in the CA pool.
