126 head-to-head benchmarks against hpke-rs and rust-hpke. hpke-ng wins 103, ties 19, loses 4. ML-KEM-1024 decap −55%, X25519 decap −41%, export −72% to −76%, end-to-end roundtrip −30%, plus a type system that catches four classes of bug at compile time.

1 min readVerifpal 0.51.0 tightens the analysis engine's treatment of password-qualified values, checked ASSERT? assertions, and AEAD associated data, all on the back of excellent bug reports from the community.
7 min readWhy Symbolic Software agrees with Soatok's position on hybrid post-quantum constructions: hybrids are compelling for KEMs, far less necessary for signatures, and the real risk is migration friction.
6 min readFive proof-of-concept exploits against ML-DSA, ML-KEM, Ed25519, and ChaCha20 demonstrate three classes of semantic gap in hax's Rust-to-F* extraction pipeline, where verified models diverge from deployed code.
11 min readSymbolic Software is recommending post-quantum native design for all new cryptographic systems. This post examines the evidence behind that recommendation, its limitations, and the epistemic questions the industry should be confronting.
11 min readWe're opening 50 spots for students at Lebanese universities to take the Applied Cryptography course online, completely free of charge, starting June 2026. Applications are open now.
3 min readWe tested 15 ML-KEM and ML-DSA implementations across 5 languages, and found two conformance gaps and no security vulnerabilities.
4 min readWe're looking for a research intern to join us this summer and contribute to new papers on real-world cryptographic constructions.
3 min readAn examination of CE Labs' TLS implementations reveals 75% of valid ECDSA signatures rejected, authentication tags silently dropped, no certificate validation, and remote denial-of-service vectors.
11 min readVerifpal's analysis engine has been redesigned with a unified equational theory, provenance-tagged values, a formally grounded deduction loop, and a bounded-depth search that runs 3x faster, plus updated tooling across the board.
11 min readVerifpal now runs entirely in the browser via WebAssembly. The new Workbench at verifpal.com/workbench lets anyone write, verify, and visualize cryptographic protocol models with zero installation.
