Online Password Generator
The DirJournal Password Generator is a security tool that produces cryptographically random passwords entirely in your browser, using the Web Crypto API with no server round-trip.

Characters Used
Passwords are generated entirely in your browser using the Web Crypto API (crypto.getRandomValues). Nothing is sent to a server, logged, or stored.
How the Password Generator Works
- 1Web Crypto API (
crypto.getRandomValues). Each character index is drawn from the browser's native cryptographically secure pseudorandom number generator (CSPRNG). We apply rejection sampling on top of the raw 32-bit output so the character distribution stays uniform — no modulo bias, no shortcuts. - 2Entropy. A 12-character password drawn from uppercase, lowercase, digits, and symbols carries roughly
78 bitsof entropy — enough that a modern brute-force attack against a properly-hashed password would take billions of years on current hardware. Every extra character compounds the difficulty exponentially, which is why the slider goes up to 64. - 3Client-side, zero-knowledge execution. The generator runs entirely in your browser tab. The password is never transmitted over the network, never logged, and never written to any DirJournal database. Close the tab and it's gone.
Frequently Asked Questions
What makes a password truly strong?
A length of 12+ characters, a mix of uppercase, lowercase, numbers, and symbols, and high cryptographic entropy.
Is it safe to use an online password generator?
Yes, if it runs entirely client-side. Our tool uses the native Web Crypto API in your browser; your password never travels over the internet or touches a server.
Can this tool generate a 64-character password?
Yes, you can scale the slider up to 64 characters to secure high-encryption environments, databases, and SSH keys.
