OpenSSL 3.5 with PQC support

Long awaited version 3.5 of OpenSSL was published on April 8th. It comes with native support for NIST published PQC standards:

  • FIPS 203 – ML-KEM – Module Lattice Based Key Encapsulation Mechanism
  • FIPS 204 – ML-DSA – Module Lattice Based Digital Signature Algorithm
  • FIPS 205 – SLH-DSA – Stateless Hash Based Digital Signature Algorithm

OpenSSL 3.5 is an LTS release and will be supported until 2030.

Looking forward to testing the PQC capabilities of the latest OpenSSL version – will share an update soon!
