leviathan.3xi.club/covcom animated protocol diagram for my upcoming project

leviathan-crypto post-quantum key establishment, live in the browser. ml-kem ceremony, encrypted messaging, annotated wire frames. this demo let's you see exactly what crosses the wire and what doesn't. demo: leviathan.3xi.club/kyber source: github.com/xero/leviath...

leviathan.3xi.club/kyber post-quantum cryptography demo simulating a complete ML-KEM (kyber) key encapsulation ceremony between two browser-side clients. Each wire frame is expandable, revealing the raw nonce, ciphertext, Poly1305 tag, and AAD. sauce: github.com/xero/leviath...

LAC-DR1.ANS, 1997-04-15 from dark domain - the artpacks.acid.org collection (CD-ROM)

github.com/xero/claudec... VULN DISCLOSURE: Claude code's HTTP hooks can silently rewrite your shell commands while the UI shows the original. H1 report closed as wontfix: "workspace trust threat model." So here's the full PoC. Decide for yourself if that trust dialog is doing enough.

github.com/xero/leviath... leviathan-crypto v1.4.0 XChaCha20Seal: bind key, call encrypt(), done! fresh nonce every call w/ no management needed. XChaCha20StreamSealer: chunked AEAD for large payloads w/ per-chunk nonces and position binding. bun i leviathan-crypto (on npm you pleb)

github.com/anthropics/claude-code/ "open source" is generous. it's just scripts, plugins, 'n examples. the actual application source, the 2200 ts files i spent all day in, aren't even in there. this repo contains install scripts, the plugins directory, some examples, and a CHANGELOG. XD

npmjs.com/package/lvthn v1.3.1 with cli worker pooling & wasm simd optimization! bun i -g lvthn # or npm install lvthn lvthn keygen --armor -o my.key cat secret.txt | lvthn encrypt -k my.key --armor > secret.enc supports: serpent-256 (ctr mode w/ hmac-sha256) & xchacha20-poly1305

unix is magical

github.com/xero/leviath... leviathan-crypto v1.20: bringing WebAssembly SIMD acceleration to serpent-256 and ChaCha20. inter-block 4-wide parallelism delivering 2–3x single-thread throughput gains across V8, SpiderMonkey, and JSC! npmjs.com/package/levi...

github.com/xero/leviath... im trying to write the best security policy i can for this project. suggestions welcomed.

i think these public attestation signing are cool for published artifacts. does anyone else? search.sigstore.dev?logIndex=118... created from this release github.com/xero/leviath...

github.com/xero/cchat a terminal interface for claude code that uses your existing plan subscription. wraps the claude cli in a prompt_toolkit shell with vi keybindings, session persistence, file injection, and a planning workflow that produces task files for autonomous agents. #claude #agentic

shoutout to @bunjavascript.mbdio.uk these single-file executable bins are so hype! watch me install my new crypto lib and build the cli tool in under 0.1s, then watch my demo tool use XChaCha20Poly1305 to encrypt and decrypt a 1gb file in 2s ;D #bun #js #typescript #crypto #cryptography #wasm #cli

v1 (and 2 stream ciphers) were not fast enough. so let's use worker pools! serpent-256 x4 faster! and pooling XChaCha20-Poly1305 makes the tool ridiculous. testing on a 1.3gb file, 2.4sec encrypt or decrypt. wasm is so hype! #crypto #wasm #typescript #asciiart #teminal

what good is a cli tool w/o an ascii art animation? esp when encrypting gigs of "backups" ;D #ascii #terminal #crypto #cli #shell #codeart #cryptography

github.com/xero/leviath... Zero-dependency WebAssembly cryptography library for TypeScript: Serpent-256, XChaCha20-Poly1305, SHA-2/3, HMAC, HKDF, and Fortuna CSPRNG, with a strictly typed API built on vector-verified primitives #wasm #crypto #typescript #javascript #cryptography

because I'm filthy and guilty, dastardly mastery, my felony ascii has to be a bastard's masterpiece

github.com/xero/text0wn... the "BLOCKTOBER" release brings new plain text file export, fixes for tool context switching and move mode, html minification, new selection tool keyboard features, and finally we've updated to vitest v4 while optimizing the tests for better memory usage! 🎃

mode3 by phlogiston aka @strotchy.bsky.social is such an underrated album! "cyberaxe cafe" is cyberpunk vibe www.8bitpeoples.com/products/520...

"two men look out from behind the same bars... one sees the mud, the other the stars" is one of those quotes about perception and chaos magic that has always really resonated w/ me. remember we are all trapped here together, but no one can stop you from shaping your own reality

"yinz get rad" is pittsburghees that roughly translates to "everyone be awesome" . graff motivation pgh ironcity slaps

fuck do i hate yaml. even with an in editor linter/lsp i can barely write this shit. it's undoubtedly fueled by my distaste for white space centric languages
