OpenSSL 4.1.0 Alpha1 Released With DTLS 1.3 and Faster Post-Quantum Cryptography

OpenSSL 4.1.0 Alpha1 adds DTLS 1.3 support, ML-DSA and ML-KEM post-quantum optimizations, and GREASE TLS compatibility, intended for testing only.

The alpha preview of OpenSSL 4.1.0 implements RFC 9147 DTLS 1.3 for UDP-based applications and integrates DTLS into the SSL listener API. It accelerates ML-DSA signatures and ML-KEM encapsulation with AVX-512 and VAES optimizations on x86_64, and adds GREASE (RFC 8701), IKEv2 KDF support, and Elbrus2000 (e2k) targets. The release is intended for testing and development, not production, and removes Windows-on-Itanium and Windows CE build targets.

OpenSSL’s new alpha build speeds up post-quantum crypto

OpenSSL 4.1.0 alpha1 adds DTLS 1.3 support and speeds up ML-DSA and ML-KEM post-quantum operations across several architectures.

The OpenSSL project released the first alpha of OpenSSL 4.1.0, months before general availability. The build adds DTLS 1.3 (RFC 9147) to secure UDP-based traffic such as VPNs, video calls and IoT, and includes optimized ML-DSA and ML-KEM operations for ppc64le, s390x and x86_64 plus AVX-512 acceleration for SHAKE hashing and AES-CBC decryption. Breaking changes include a new Net::Curl::Easy dependency for tsget, dropped Windows-on-Itanium and Windows CE support, and replacement of the no-ecdsa/no-ecdh Configure options with no-ec. It also adds GREASE support (RFC 8701), a DTLS mode for the SSL listener API, IKEv2 KDF support, and initial Elbrus2000 processor architecture support.
