PHP executes constant-time crypto – zero-knowledge benchmark inside

I built ULTRA – a pure-PHP VM that runs encrypted code without eval, tmpfiles, or key leakage.

Highlights: - Timing-safe AES-256-CTR + HMAC-SHA-256 - Memory isolation via FFI/mprotect - Zero-knowledge: run the benchmark without source/keys - Security audit passed (page alignment, permissions, generic errors)

Run the impossible: docker run --rm phpnext/ultra-bench
