mongoc_auto_encryption_opts_set_schema_map

void
mongoc_auto_encryption_opts_set_schema_map (mongoc_auto_encryption_opts_t *opts,
                                            const bson_t *schema_map);

• opts: The mongoc_auto_encryption_opts_t
• schema_map: A bson_t where keys are collection namespaces and values are JSON schemas.

Supplying a schema map provides more security than relying on JSON Schemas obtained from the server. It protects against a malicious server advertising a false JSON Schema, which could trick the client into sending unencrypted data that should be encrypted.

Schemas supplied in the schema map only apply to configuring automatic encryption for Client-Side Field Level Encryption. Other validation rules in the JSON schema will not be enforced by the driver and will result in an error.

The following is an example of a schema map which configures automatic encryption for the collection db.coll:

{
     "db.coll": {
         "properties": {
         "encrypted_string": {
             "encrypt": {
             "keyId": [
                 {
                 "$binary": {
                     "base64": "AAAAAAAAAAAAAAAAAAAAAA==",
                     "subType": "04"
                 }
                 }
             ],
             "bsonType": "string",
             "algorithm": "AEAD_AES_256_CBC_HMAC_SHA_512-Deterministic"
             }
         }
         },
         "bsonType": "object"
     }
 }

The schema map does not apply to collections encrypted with: Queryable Encryption. Use mongoc_auto_encryption_opts_set_encrypted_fields_map() instead.
