Zombillenium - English

Client-side tool to generate/verify password hashes with realistic parameters. Helpful for debugging integrations and understanding how salts, memory, and iterations affect cost. Runs locally—no passwords leave your browser.

Your data security is our top priority. All hashing and verification happen in this browser. This tool does not store or send your password nor hashes outside of the browser. See source code in: https://github.com/authgear/authgear-widget-password-hash

Here’s a detailed and interesting content concept for Zombillenium (the French comic series by Arthur de Pins, also adapted into an animated film), tailored for an English-speaking audience. 1. The High-Concept Pitch (For New Readers) Imagine if Monsters, Inc. ran a gothic theme park, The Office handled the payroll, and What We Do in the Shadows wrote the employee handbook. Zombillenium isn’t just a haunted attraction. It’s a real supernatural refuge. In this world, when a human dies in a tragic accident near the park, they don’t go to heaven or hell—they get a mandatory job offer as a zombie, vampire, or werewolf. The twist? They have to keep working the roller coasters and cotton candy stands for eternity.

The protagonist, , is a safety inspector and single father who gets killed in a freak accident on park grounds. Now he’s a zombie forced to work the “Tunnel of Terror.” His arc isn’t learning to be a monster—it’s learning to be a dad while decomposing. He has to hide his rotting face from his human daughter, who keeps visiting the park.

How to use the Password Hash Generator

Step 1.
Enter a password
  • Open the Generate tab and type a demo password (avoid real credentials).
Step 2.
Select an algorithm
  • For new systems, Argon2id is generally recommended.
Step 3.
Set parameters:
  • Argon2id: Memory (MiB), Iterations (t), Parallelism (p).
  • bcrypt: Cost (2cost rounds).
  • scrypt: N (power of two), r, p.
  • PBKDF2: Iterations and digest (SHA-256/512).
Step 4.
Generate Password Hash
  • Click Generate Password Hash. Copy the encoded string.
Step 5.
Verify Password Hash
  • Switch to Verify Password Hash to test a password + encoded hash pair.

Is it safe to use this with real passwords?

All hashing happens locally in your browser. For your own safety, avoid using production secrets in any online tool.

Which hashing function should I use?

For new systems, Argon2id is generally recommended. bcrypt and scrypt are widely deployed; PBKDF2 is a compatibility fallback. Always benchmark and choose parameters that meet your latency targets.

How long should hashing take?

Many teams target ~250–500ms in the authentication path. Pick the slowest settings that still keep UX smooth on your production hardware.

Why won’t my framework verify the hash?

Common issues: whitespace/line endings, encoding mismatch (hex vs Base64), bcrypt prefix differences ($2a$ vs $2b$), or forgetting a pepper.

What salt length should I use?

16–32 bytes of random data is standard. The tool defaults to secure randomness and shows length and encoding.
