Salt Generator
Generate cryptographic salts for password hashing online for free.
Hash with Salt (demo)
About This Tool
Generate random cryptographic salts for use in password hashing with bcrypt, Argon2, PBKDF2, and other algorithms. Salts ensure identical passwords produce different hashes.
How to Use
Set Length
Choose salt length in bytes (16-64 bytes recommended).
Choose Format
Select output format: hex, base64, or base32.
Generate
Click Generate and copy the salt.
Use Cases
Password Hashing
Generate salts for bcrypt, Argon2, and PBKDF2 password hashing.
Frequently Asked Questions
