0xKaishakuninI have updated my #OpenSSL #PQC #benchmark after realising how to get #SecP256r1MLKEM768 and #SecP384r1MLKEM1024 as groups for #TLS
Turns out the performance hit of using PQC #HPKE instead of just the #ECC is neglectable
Benchmarking post quantum cryptography with OpenSSL 3.5: X25519MLKEM768
This Article can be downloaded as PDF file. Generated with AsciiDoctor-PDF UPDATE (20250914): It turned out that s_time did have problems with the new PQC TLS Groups. I found a workaround and added a new Benchmark for all TLS1.3 Groups. Benchmarking OpenSSL and Post Quantum Cryptography: X25519MLKEM768 Since version 3.5, OpenSSL natively supports PQC keys and signatures. There is no need to use OQS-Provider as an provider to use PQC signatures and KEMs anymore.
