ARGON2(1)

💖 ARGON2 💖

okay bestie, sit down, hydrate, and let me tell you about argon2 — it's a User Command, it lives in section 1 of the manual, and it is literally out here generating argon2 hashes from your terminal like it's nothing. no cap. 👑

✨ NAME ✨

argon2 — generate argon2 hashes 🧂✨

🎀 SYNOPSIS 🎀

argon2 salt [OPTIONS]

🦋 DESCRIPTION 🦋

So the whole vibe is: you generate Argon2 hashes straight from the command line. that's the job. that's the whole job. 💅

The salt — that's the first argument you hand over to the command — has to be at least 8 octets long, periodt. no shortcuts, no "but bestie it's just a little salt". eight octets minimum. and your password? that comes in on standard input. so you're piping it in, not typing it as an argument. slay. 🫶

By default it uses the Argon2i variant, which is the one where memory access is independent of secret data — and that's the preferred one for password hashing and password-based key derivation. it's giving ✨responsible choices✨. iykyk.

🌸 OPTIONS 🌸

• -h — display tool usage 📖 (yes, help. we love her.)
• -d — use Argon2d instead of Argon2i (Argon2i is the default, don't forget)
• -id — use Argon2id instead of Argon2i (Argon2i is still the default, bestie, it's not going anywhere)
• -t N — sets the number of iterations to N (default = 3) 🔁
• -m N — sets the memory usage of 2^N KiB (default = 12) 🧠
• -p N — sets parallelism to N threads (default = 1) 🧵
• -l N — sets hash output length to N bytes (default = 32) 📏
• -e — output only the encoded hash 🎀
• -r — output only the raw bytes of the hash 🥩
• -v (10|13) — Argon2 version (defaults to the most recent version, currently 13) 🔢
