may 3-4, 2026 . six rust crates . single-binary friends

the stack.

six rust crates shipped between 2026-05-03 and 2026-05-04. they cluster around three themes: post-quantum cryptography (mlkem-rs, mlkem-tls, pqfetch), claude-code tooling (bashward, skill-scan), and editor plumbing (pluvgo). live download counts and latest versions are pulled from crates.io on page load below; the cards link out to each crate's landing.

post-quantum cryptography
mlkem-rs FIPS 203 ML-KEM in pure rust. all three security levels, 180 NIST ACVP vectors, 11 kani formal proofs, dudect timing evidence.
post-quantum audit-ready no_std
v... ... dl
mlkem-tls X25519MLKEM768 / X25519MLKEM1024 hybrid kem per draft-ietf-tls-ecdhe-mlkem. wire-compatible with what cloudflare and rustls 0.23.27+ ship.
hybrid tls no_std
v... ... dl
pqfetch tls post-quantum readiness scanner. "is your favorite server pq?" in three columns. 14 of 17 big-name hosts ship X25519MLKEM768 today.
scanner cli tls
v... ... dl
claude code tooling
bashward checkpoint and rewind for bash side-effects in claude code. closes the gap claude's built-in /rewind does not cover. APFS clonefile snapshots, no-block hook.
claude-code snapshot cli
v... ... dl
skill-scan local prompt-injection scanner for claude skills, MCP server tool descriptions, and AGENTS.md. ten heuristic detectors, no LLM in the loop, ci-friendly.
claude-skills security linter
v... ... dl
editor plumbing
pluvgo fast neovim plugin manager. the only one you can run before neovim is on PATH. parallel git, deterministic lockfile, lua runtime shim.
neovim plugin-manager cli
v... ... dl

each crate ships under MIT or Apache-2.0, has its own GitHub repo with cross-platform release binaries, and a dedicated landing on this domain with an animated demo gif. the cryptographic crates ship audit-readiness packs (SECURITY.md, SIDE_CHANNELS.md, AUDIT_SCOPE.md, FORMAL_VERIFICATION.md, SUPPLY_CHAIN.md). nothing here has been audited; mlkem-rs explicitly recommends rustcrypto's audited ml-kem for production.
