Hash Compare

Generate secure credentials without sending anything to a server

Passwords, OTPs, UUIDs and hashes are all generated using your browser's built-in cryptographically secure random number generator and hashing functions — meaning the values you create here never travel over the network.

What's included

Password Generator — a random password of any length using a wide character set, automatically copied to your clipboard.
OTP Generator — a random 6-digit one-time code, useful for testing flows that need a sample OTP.
UUID v4 / NanoID — unique identifiers for development, databases or testing.
Hash Generator — SHA-256, SHA-384, SHA-512, SHA-1 and MD5 hashes of any text.
Hash Compare — quickly check whether two hash strings match.

Is MD5 still considered secure?

MD5 is widely considered cryptographically broken for security purposes like password storage, though it's still commonly used for basic checksums and file integrity checks where collision resistance isn't critical.

Are generated passwords stored anywhere?

No — each password is generated fresh in your browser and copied to your clipboard, with nothing logged or saved beyond that.

What's the difference between a UUID and a NanoID?

Both generate unique identifiers, but UUID v4 follows a fixed 36-character standard format widely used in databases, while NanoID is shorter and URL-friendly, often preferred for use in web links.

Can I verify that a file wasn't tampered with using the hash generator?

Yes — generate a SHA-256 hash of the file content and compare it against a known-good hash using Hash Compare; any difference means the content has changed.
