Random Salt Generator
Generate a random salt for password hashing and key derivation. All values are generated on your device using a cryptographically secure random generator — nothing is sent to a server.
Everything runs in your browser. Your data is never sent to our servers.
Example
Example Input
16 bytes
Example Output
Hex / Base64 (salt)
How to Use
- 1Open "More settings" to adjust parameters (e.g. size/length) if needed.
- 2Click the Generate button.
- 3Copy the result with the Copy button.
About Random Salt
A salt is a random value added when hashing a password or deriving a key, so two identical passwords produce different hashes and rainbow tables become useless.
A salt must be unique per password and need not be secret (stored alongside the hash). This tool generates a random salt (default 16 bytes) in hex and Base64.
Use this salt with PBKDF2, scrypt, or Argon2. Many modern password-hashing functions generate and store the salt automatically.
FAQ
Are my data or keys sent to a server?
No. Random Salt runs entirely in your browser using the Web Crypto API and client-side libraries. Your data, passwords, and keys never leave your device.
