Space Engineers Server Password Generator

There's no plain-text password field. The server only reads ServerPasswordHash and ServerPasswordSalt, so the password has to be hashed first. That's deliberate: anyone who gets a copy of your config (a backup, a support ticket, a screenshot) still doesn't learn the actual password.

When a player joins, the server runs the password they typed through PBKDF2 with the stored salt and checks the result against the stored hash. The salt is a random value that makes your hash unique, so two servers with the same password still end up with different hashes.

Yes. It uses the same derivation as the dedicated server GUI: PBKDF2 with SHA-1, 10,000 iterations, a 16-byte salt and a 20-byte hash, Base64-encoded. Generate with the same salt and you get a byte-identical hash.

Each run creates a fresh random salt, and a new salt means a new hash. Every pair is valid; just make sure the hash and salt you paste into the config come from the same run. To reproduce an earlier hash, paste its salt into the salt field.

The plain password you typed here, the same one they enter when joining the server. The hash and salt never leave the config file.

It's not official, and Host Havoc isn't affiliated with Keen Software House. The hashing runs in your browser with the built-in Web Crypto API, so the password never leaves your machine. You can load the page, go offline, and it still works.
