Repackaged version of mongodb-client-encryption

This is a convenience package that will install all prebuilds for all supported platforms, to the contrary to the upstream package that constraint the installation only to the runtime platform (os/cpu). This typically enable cross building an Electron application.

The package is cleaned up to only embbed the necessary.

MongoDB Client Encryption

The Node.js wrapper for libmongocrypt

Installation

You can install mongodb-client-encryption with the following:

npm install mongodb-client-encryption

Development

Setup

Run the following command to build libmongocrypt and setup the node bindings for development:

bash ./etc/build-static.sh

Testing

Some tests require a standalone server to be running with authentication enabled. Set up a single server running with the following conditions:

param	value
host	localhost
port	27017

This is the standard setup for a standalone server with no authentication.

Run the test suite using:

npm test

Deprecation Notice

There are breaking changes planned for this package. In the next major version, callbacks will be removed from the public API on all asynchronous functions. Additionally, the classes documented here will be moved into node-mongodb-native.

AutoEncrypter

An internal class to be used by the driver for auto encryption NOTE: Not meant to be instantiated directly, this is for internal use only.

new AutoEncrypter(client, [options])

Param	Type	Description
client	`MongoClient`	The client autoEncryption is enabled on
[options]	`AutoEncryptionOptions`	Optional settings

Create an AutoEncrypter

Note: Do not instantiate this class directly. Rather, supply the relevant options to a MongoClient

Note: Supplying options.schemaMap 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 schemaMap 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.

Example (Create an AutoEncrypter that makes use of mongocryptd)

// Enabling autoEncryption via a MongoClient using mongocryptd
const { MongoClient } = require('mongodb');
const client = new MongoClient(URL, {
  autoEncryption: {
    kmsProviders: {
      aws: {
        accessKeyId: AWS_ACCESS_KEY,
        secretAccessKey: AWS_SECRET_KEY
      }
    }
  }
});

await client.connect();
// From here on, the client will be encrypting / decrypting automatically

Example (Create an AutoEncrypter that makes use of libmongocrypt's CSFLE shared library)

// Enabling autoEncryption via a MongoClient using CSFLE shared library
const { MongoClient } = require('mongodb');
const client = new MongoClient(URL, {
  autoEncryption: {
    kmsProviders: {
      aws: {}
    },
    extraOptions: {
      cryptSharedLibPath: '/path/to/local/crypt/shared/lib',
      cryptSharedLibRequired: true
    }
  }
});

await client.connect();
// From here on, the client will be encrypting / decrypting automatically

autoEncrypter.cryptSharedLibVersionInfo

Return the current libmongocrypt's CSFLE shared library version as { version: bigint, versionStr: string }, or null if no CSFLE shared library was loaded.

autoEncrypter.askForKMSCredentials()

Ask the user for KMS credentials.

This returns anything that looks like the kmsProviders original input option. It can be empty, and any provider specified here will override the original ones.

const filter = {};

const result = await clientEncryption.rewrapManyDataKey(filter);
if (result.bulkWriteResult != null) {
 // keys were re-wrapped, results will be available in the bulkWrite object.
}

Example

// attempting to rewrap all data keys with no matches
const filter = { _id: new Binary() } // assume _id matches no documents in the database
const result = await clientEncryption.rewrapManyDataKey(filter);

const { deletedCount } = await clientEncryption.deleteKey(id);

if (deletedCount != null && deletedCount > 0) {
  // successful deletion

Finds a key in the keyvault with the specified _id.

Returns: Promise.<DataKey> - Returns a promise that either resolves to a DataKey if a document matches the key or null if no documents match the id. The promise rejects with an error if an error is thrown.
Example

// getting a key by id
const id = new Binary(); // id is a bson binary subtype 4 object
const key = await clientEncryption.getKey(id);
if (!key) {
 // key is null if there was no matching key
}

clientEncryption.getKeyByAltName(keyAltName)

Param	Type	Description
keyAltName	`string`	a keyAltName to search for a key

Finds a key in the keyvault which has the specified keyAltName.

Returns: Promise.<(DataKey|null)> - Returns a promise that either resolves to a DataKey if a document matches the key or null if no documents match the keyAltName. The promise rejects with an error if an error is thrown.

// adding an keyAltName to a data key
const id = new Binary();  // id is a bson binary subtype 4 object
const keyAltName = 'keyAltName';
const oldKey = await clientEncryption.addKeyAltName(id, keyAltName);
if (!oldKey) {
 // null is returned if there is no matching document with an id matching the supplied id
}

Param	Type	Description
_id	`ClientEncryptionDataKeyId`	The id of the document to update.
keyAltName	`string`	a keyAltName to search for a key

Adds a keyAltName to a key identified by the provided _id.

This method resolves to/returns the old key value (prior to removing the new altKeyName).

If the removed keyAltName is the last keyAltName for that key, the altKeyNames property is unset from the document.

Returns: Promise.<(DataKey|null)> - Returns a promise that either resolves to a DataKey if a document matches the key or null if no documents match the id. The promise rejects with an error if an error is thrown.

Example

// Encryption with callback API
function encryptMyData(value, callback) {
  clientEncryption.createDataKey('local', (err, keyId) => {
    if (err) {
