mongoc_client_encryption_datakey_opts_set_masterkey()

Synopsis

void
mongoc_client_encryption_datakey_opts_set_masterkey (
   mongoc_client_encryption_datakey_opts_t *opts, const bson_t *masterkey);

Identifies the masterkey for the Key Management Service (KMS) provider used to encrypt a new data key.

Parameters

• opts: A mongoc_client_encryption_datakey_opts_t

• masterkey: A bson_t document describing the KMS provider specific masterkey.

Description

Setting the masterkey is required if using AWS KMS, and masterkey must have the form:

{
   region: <string>, // Required.
   key: <string>, // Required. The Amazon Resource Name (ARN) to the AWS customer master key (CMK).
   endpoint: <string> // Optional. An alternate host identifier to send KMS requests to. May include port number.
}

The value of “endpoint” is a host name with optional port number separated by a colon. E.g. “kms.us-east-1.amazonaws.com” or “kms.us-east-1.amazonaws.com:443”

This function is only applicable for the “aws” KMS provider. It is not applicable for creating data keys with the “local” KMS provider (as configured in mongoc_client_encryption_opts_set_kms_providers()).
