How to use the Hash Generator
Create integrity hashes locally with Web Crypto. The result follows “Input bytes → Web Crypto SHA digest” and is designed for situations such as verify a downloaded file. Inputs are handled immediately in your browser with no account required.
How it works
Input bytes → Web Crypto SHA digest
Most processing stays in your browser instead of sending inputs to our server. Verify important financial or contractual decisions against an authoritative source.
Useful examples
- Verify a downloaded file
- Create a text checksum
- Compare hashes before and after changes
