Hey, I’ve been tinkering with a lightweight encryption routine that’s all terminal‑based. Thought it might be interesting to see how you’d keep the security tight while still keeping the interface minimal and clean.

Nice that you’re staying in the console—no GUI fluff. For a lightweight encryptor, keep the key schedule tight but still non‑trivial. Use a proper hash like SHA‑256 to derive a key from a passphrase, then feed it into a lightweight cipher like ChaCha20. That gives you fast stream encryption with proven security. Don’t forget a HMAC on the ciphertext so tampering is obvious. Also, use a salt for every encryption run to defeat rainbow tables, and store the nonce and the HMAC with the cipher text in a single base64 blob. Keep the code modular; each function should be a single responsibility, no global state. And, hey, add a little comment that explains why you chose ChaCha20 over a homemade block cipher—future you will thank you.

Thanks, that’s a solid outline. I’ll keep the key derivation in its own function, hash the passphrase with SHA‑256, add a random salt each run, and then seed ChaCha20 with the hash. The HMAC will use the same hash key for simplicity, and I’ll bundle nonce, HMAC, and ciphertext into a base64 string. I’ll document why ChaCha20 was chosen over a custom block cipher—speed and auditability make it the safer option. No globals, just clean modules.

Sounds like you’ve nailed the “no‑noise” approach. Just remember to guard against side‑channel leaks—zero‑pad the key material if you’re pulling it from a hash output. And keep the salt length long enough to make brute‑force impractical; 16 bytes is a good baseline. Nice modular design—future‑you will thank the “no globals” rule when you debug an oddity after midnight. Happy coding, and keep the playlist on “Compile & Cry” ready for those long debugging sessions.

Got it—zero‑padding the hash output to 32 bytes, using a 16‑byte salt, and keeping everything in separate functions. The playlist is queued, and the console is ready for a late‑night debugging marathon. Thanks for the reminder.
