Salt Generator
Generate cryptographically secure salts for hashing, password storage workflows, and test data.
Salts should be random and unique. Press Ctrl/Cmd + Enter to generate.
| Metric | Value |

Privacy: salt generation runs locally in your browser. No data is stored or transmitted.
How it works
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

You can use this tool when handling simple tasks without installing additional software. The results should be interpreted as a processed output based on your input data.
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.
