Verifpal 0.80.0: Nuancing Weak Cryptography Modeling and Witness-Based Unlinkability

Verifpal 0.80.0 lets a model declare that a particular piece of cryptography is broken (weak, forgeable, and from a chosen phase onward) instead of approximating the break with a list of leaked values, and decides unlinkability queries by searching for a concrete link witness that it then reports back to you.

How Jevil works

A playground-first, interactive explainer for Jevil, a post-quantum, transparent few-time signature scheme whose key-recovery threshold is a single sharp cliff rather than a slow slope.

hpke-ng: Faster, Smaller, Harder HPKE for Rust

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.

Hybrid Constructions Are a Safety Blanket, and That's Fine

Why 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.

Recommending Post-Quantum Native Design Under Epistemic Duress

Symbolic 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.

Even More Bugs in CE Labs' libcrux: ML-DSA

Three findings in libcrux's ML-DSA implementation: a verifier norm check that is dead code due to a wrong constant, a missing bounds check in hint deserialization, and a wrong multiplication specification that renders AVX2 proofs unsound.
