Marcus pulled the bag from his right pocket. He tossed it. Carlos caught it, sniffed the seal, and nodded.

“Shut up,” Marcus whispered.

Outside, gasping in the rain, Marcus finally hit the emergency tone.

Detective Marcus Cole was a one-man equation the department didn’t like to solve. They called him “1x2”—one narcotics officer with two faces. By day, he was the golden boy of the DEA’s field office, clean-shaven, sharp-jawed, with a binder full of successful busts. By night, he sat across from the very men he was supposed to destroy, sipping whiskey from a glass they’d poured.

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 (2^cost 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.
