OpenSSL Providers

OpenSSL 3.0 introduced the provider concept as a flexible way to supply cryptographic algorithms and related functionality. A provider can implement a wide range of features, including encryption, key management, and certificate handling. This modular design makes it easier to extend OpenSSL with new algorithms or integrate it with external cryptographic frameworks.

CNG Provider

We are preparing to release an OpenSSL provider for CNG in Q3 2025. This provider will allow OpenSSL applications to access keys, certificates, and algorithms through Microsoft’s Cryptography Next Generation (CNG) interface. It is designed to integrate OpenSSL more closely with the Windows cryptographic ecosystem while maintaining compatibility with existing OpenSSL-based applications.
