4-wide inter-block SIMD: each v128 register lane holds word w from a different block (counters ctr, ctr+1, ctr+2, ctr+3). serpent uses the same parallelism model as ChaCha20 CTR-4
100
xero @xerostyle.bsky.social · 01/04/2026
parallelism: encryption and decryption distribute 64kb chunks across a worker pool sized to `hardwareConcurrency`. each worker owns an isolated WASM instance with no shared memory between workers.
100
xero @xerostyle.bsky.social · 01/04/2026
integrity: any modification to a ciphertext chunk causes that chunk's authentication to fail. The entire decryption is rejected with no partial plaintext produced.

xero @xerostyle.bsky.social · 01/04/2026
key derivation: scrypt (N=32768, r=8, p=1) for passphrases → 32-byte master key with a fresh random 32-byte salt per encryption.

ive found the web chat is much "smarter" than code's plan mode. it's very sandboxed and cannot do research. running cchat in your own sandbox let's the planning agent install deps, run tests, read files, etc that produces _MUCH BETTER_ tasks. when ready call /handoff and let an agent run the task
