keyOrigin

The source of the key material for the specified KMS key.

When this value is AWS_KMS, KMS created the key material. When this value is EXTERNAL, the key material was imported or the KMS key doesn't have any key material.

The only valid values for DeriveSharedSecret are AWS_KMS and EXTERNAL. DeriveSharedSecret does not support KMS keys with a KeyOrigin value of AWS_CLOUDHSM or EXTERNAL_KEY_STORE.
