💖 NAME 💖

okay so bestie, zxcvbn-password-strength is literally here to evaluate password strength ✨ that's the whole gig, that's the vibe.

ngl you're reading a page from the User Contributed Perl Documentation collection, and the man page itself is filed under ZXCVBN-...TRENGTH(1) (yes the title is truncated, no we don't know why, we simply do not perceive it 🙈).

🌸 VERSION 🌸

version 1.1.3 — that's the one, that's the current era 💅

🦋 SYNOPSIS 🦋

run it like this:

zxcvbn-password-strength [options] [password...]

so you hand it a password (or a bunch of them, go off 👑), maybe throw in some options, and it tells you how strong they are. iconic behaviour honestly.

here's the options menu, iykyk:

  • --input <field>=<value>, -i <field>=<value> — feeds in names and values that should be treated as "obvious guesses", like your account name, your actual real-life name, your company's name, all that stuff that attackers try first 🫶 (yes bestie, your own name is a terrible password, we've all been there 😭)
  • --json, -j — spits out a stream of JSON objects with the full details for every single password. skip this flag and you only get the password and its score, which is cute but lowkey minimal ✨
  • --from <file>, -f <file> — opens up the file you gave it and treats each line as a password to evaluate 📄 and plot twist: you can pass this more than once, stack 'em up, the more the merrier 💖
  • --help — prints the help message and then dips out, bye 👋
  • --version — prints the script version and exits, quick little flex 💅
