void
mongoc_client_encryption_datakey_opts_set_keymaterial (
   mongoc_client_encryption_datakey_opts_t *opts,
   const uint8_t *data,
   uint32_t len);

Sets the custom key material to be used by the data key for encryption and decryption.

• opts: A mongoc_client_encryption_datakey_opts_t
• data: A pointer to the bytes constituting the custom key material.
• len: The length of the bytes constituting the custom key material.

Key material is used to encrypt and decrypt data. If custom key material is not provided, the key material for the new data key is generated from a cryptographically secure random device.
