Installation Requirements

Overview

Learn about the applications and libraries you must install to use Client-Side Field Level Encryption (CSFLE).

What You Need

Before you can use CSFLE, you must set up the following items in your development environment:

(Optional) Download the Automatic Encryption Shared Library. The Automatic Encryption Shared Library is a preferred alternative to mongocryptd and does not require spawning a new process. mongocryptd is still supported.
Install MongoDB Enterprise Edition.
Install a MongoDB Driver Compatible with CSFLE.
Start a MongoDB instance or Atlas Cluster.

Ensure that you're using an x64 operating system. CSFLE requires x64 support.

If you're using driver version 3.0 or later, you must also complete the following steps:

Install the MongoDB.Driver.Encryption package from NuGet. This package enables automatic encryption.
If your application runs on Linux, install libmongocrypt manually. Then, set the LIBMONGOCRYPT_PATH environment variable to the absolute path of the libmongocrypt file.
If your application runs on 64-bit Linux, and you're using driver version 3.4.3 or earlier, add the following lines of XML to your .csproj file. Change the value of the <MongoDriverEncryptionVersion> element to match the version of the MongoDB.Driver.Encryption package that you have installed.

<PropertyGroup>
    <!-- replace the version here with your package version -->
    <MongoDriverEncryptionVersion>3.4.2</MongoDriverEncryptionVersion>
    <MongoDriverEncryptionPath>$(NuGetPackageRoot)mongodb.driver.encryption\$(MongoDriverEncryptionVersion)</MongoDriverEncryptionPath>
</PropertyGroup>
<PropertyGroup>
    <!-- Suppresses the duplicate file error -->
    <ErrorOnDuplicatePublishOutputFiles>false</ErrorOnDuplicatePublishOutputFiles>
</PropertyGroup>
<!-- Ensures the correct library after build or publish -->
<Target Name="EnsureCorrectMongoEncryption" AfterTargets="Build;Publish" Condition="'$(RuntimeIdentifier)' != ''">
    <!-- Determine paths based on current operation -->
    <PropertyGroup>
        <_TargetDir Condition="Exists('$(PublishDir)')">$(PublishDir)</_TargetDir>
        <_TargetDir Condition="'$(_TargetDir)' == ''">$(OutputPath)</_TargetDir>
    </PropertyGroup>
    <!-- Copy the correct library based on runtime identifier (RID) -->
    <ItemGroup>
        <_CorrectMongoLib Include="$(MongoDriverEncryptionPath)/runtimes/linux/native/x64/libmongocrypt.so"
                          Condition="'$(RuntimeIdentifier)' == 'linux-x64'" />
        <_CorrectMongoLib Include="$(MongoDriverEncryptionPath)/runtimes/linux/native/arm64/libmongocrypt.so"
                          Condition="'$(RuntimeIdentifier)' == 'linux-arm64'" />
        <_CorrectMongoLib Include="$(MongoDriverEncryptionPath)/runtimes/linux/native/alpine/libmongocrypt.so"
                          Condition="'$(RuntimeIdentifier)' == 'linux-musl-arm64'" />
    </ItemGroup>
    <!-- Copy with overwrite -->
    <Copy SourceFiles="@(_CorrectMongoLib)"
          DestinationFolder="$(_TargetDir)"
          Condition="'@(_CorrectMongoLib)' != ''"
          OverwriteReadOnlyFiles="true" />
    <Message Text="Fixed MongoDB encryption library for $(RuntimeIdentifier)"
             Condition="'@(_CorrectMongoLib)' != ''" />
</Target>

(Optional) Download the Automatic Encryption Shared Library. The Automatic Encryption Shared Library is a preferred alternative to mongocryptd and does not require spawning a new process. mongocryptd is still supported.
Install MongoDB Enterprise Edition.
Install a MongoDB Driver Compatible with CSFLE.
Start a MongoDB instance or Atlas Cluster.

Install libmongocrypt. The libmongocrypt library contains bindings to communicate with the native library that manages the encryption.

(Optional) Download the Automatic Encryption Shared Library. The Automatic Encryption Shared Library is a preferred alternative to mongocryptd and does not require spawning a new process. mongocryptd is still supported.
Install MongoDB Enterprise Edition.
Install a MongoDB Driver Compatible with CSFLE.

Install mongodb-crypt. The mongodb-crypt library contains bindings to communicate with the native library that manages the encryption.

(Optional) Download the Automatic Encryption Shared Library. The Automatic Encryption Shared Library is a preferred alternative to mongocryptd and does not require spawning a new process. mongocryptd is still supported.
Install MongoDB Enterprise Edition.
Install a MongoDB Driver Compatible with CSFLE.
Start a MongoDB instance or Atlas Cluster.

Install mongodb-client-encryption, a Node.js wrapper for the libmongocrypt encryption library. The libmongocrypt library contains bindings to communicate with the native library that manages the encryption.

When using Node.js driver version 6.0.0 or later, mongodb-client-encryption must have the same major version number as the driver.

For example, Node.js driver v6.x.x requires mongodb-client-encryption v6.x.x.

(Optional) Download the Automatic Encryption Shared Library. The Automatic Encryption Shared Library is a preferred alternative to mongocryptd and does not require spawning a new process. mongocryptd is still supported.
Install MongoDB Enterprise Edition.
Install a MongoDB Driver Compatible with CSFLE.
Start a MongoDB instance or Atlas Cluster.

Install pymongocrypt, a Python wrapper for the libmongocrypt encryption library. The libmongocrypt library contains bindings to communicate with the native library that manages the encryption.
