💅 ARGON2-CALIBRATE — User Contributed Perl Documentation 🎀

okay bestie, welcome to the group chat, because today we're talking about argon2-calibrate — it's a lil Perl script in the User Contributed Perl Documentation section, and it's here to help you find the just right argon2 parameters. no cap. 🔥

✨ NAME ✨

argon2-calibrate — a script to find the appropriate argon2 parameters 🎯

🌸 VERSION 🌸

version 0.032 — yes she's on 0.032, she's thriving 💖

🦋 DESCRIPTION 🦋

so basically this program does the whole procedure the argon2 authors themselves recommend, step by step, and it's giving extremely thorough. here's the whole thing, all 8 steps, don't skip a single one because the details matter fr fr:

  1. Pick the type y. and if you're sitting there like "bestie idk the difference between the types" — that's okay, just choose Argon2id. main character choice honestly. 👑
  2. Figure out the maximum number of threads h that can be initiated by each call to Argon2. this one is the "parallelism" argument, so write that down. 📝
  3. Figure out the maximum amount of memory m that each call can afford. 💾
  4. Figure out the maximum amount x of time (in seconds) that each call can afford. ⏱️
  5. Select the salt length. 16 bytes is sufficient for all applications, but it can be reduced to 8 bytes in the case of space constraints. lowkey flexible, highkey useful. 🧂
  6. Select the tag (output) size. 16 bytes is sufficient for most applications, including key derivation. ✨
  7. Run the scheme of type y, memory m and h lanes and threads, using different number of passes t. Figure out the maximum t such that the running time does not exceed x. If it exceeds x even for t = 1, reduce m accordingly. And heads up bestie: if you're using Argon2i, t must be at least 3. that's not optional, that's a requirement, periodt. 💀
  8. Hash all the passwords with the just determined values m, h, and t. and then you're done!! slay. 💅
