Privacy: salt generation runs locally in your browser. No data is stored or transmitted.
Choose a byte size and output format. The salt is generated from secure random bytes using the browser crypto API.
Examples
- 16 bytes → common compact salt size
- 32 bytes → larger salt for stronger uniqueness margin
- Base64 URL-safe → convenient for configuration or storage fields
FAQ
- What is a salt?
A salt is random data added to input before hashing so identical passwords or values do not always produce identical hashes.
- Is this salt generator secure?
Yes. It uses crypto.getRandomValues() in your browser.
- What output formats are supported?
This page supports hex and base64 URL-safe output.
- Is anything stored?
No. Everything runs locally and nothing is stored or transmitted.
