DRIVERS-2718 : Summary of necessary driver changes Package the crypto-enabled libmongocrypt on platforms where it is safe to do so: Mac and Windows. For Linux, continue to package the crypto-disabled (nocrypto) builds due to the issues with OpenSSL versioning (see MONGOCRYPT-112 ). Check if the loaded libmongocrypt supports native crypto by calling mongocrypt_is_crypto_available . Only register crypto callbacks if it returns false. Document that on Linux, high-performance use cases should install libmongocrypt on the system. If possible, ensure this install takes precedence over the packaged crypto-disabled libmongocrypt. Update (2024-04-30): Drivers adding an environment variable to specify a path to libmongocrypt are recommended to use the name LIBMONGOCRYPT_PATH (consistent with Ruby driver). Context for other referenced/linked tickets mongocrypt_is_crypto_available is added in MONGOCRYPT-616 . Until it is released, libmongocrypt binaries can be downloaded from the upload-all task for the commit . I expect this work only applies to drivers that implement the crypto hooks (i.e. calling mongocrypt_setopt_crypto_hooks and friends). From this survey , this appears to be: C#, Java, Node.js, Python, Ruby.
