Libraries

Select the DAT client for your application's language. Every client uses the same DAT and certificate specifications, and provides local certificate management and DAT CMS synchronization.

How to choose

A service that issues DATs must be able to use full certificates. A service that only verifies and decrypts should use ECDSA verify-only certificates and the CMS verify-only role.

Guide structure

Each library guide covers installation, the simplest issuance and verification flow, DAT CMS connection, synchronization policy, shutdown, and error handling.
