Doors are open at Cyber Security World Asia. Swing by and ask us the hard questions: FIPS 140-3 validated cryptography, quantum-resistant algorithms you can deploy today, and why memory footprint still decides what security actually ships.

wolfProvider adds LMS signature verification for OpenSSL applications. The new verification-only support brings LMS, a stateful hash-based signature scheme standardized in RFC 8554 and NIST SP 800-208, to the OpenSSL EVP interface. Requires OpenSSL 3.6+.

I think that for secure software it's more useful than ever to measure, minimize, and verify the TCB. State a security goal (e.g. "my screen will show 'From: Alice' only for messages from Alice"); restructure software with a tiny nucleus enforcing this goal against all other LOC.
