Hash Generator
Generate SHA-1, SHA-256, SHA-384, or SHA-512 hashes for text and files.
Processing happens locally in your browser. Your files and inputs are not uploaded to our servers.
How to use Hash Generator
- Choose text input or select a local file.
- Select SHA-1, SHA-256, SHA-384, or SHA-512.
- Generate and copy the hexadecimal digest.
What Hash Generator does
A cryptographic hash converts text or file bytes into a fixed-length fingerprint. The same input produces the same digest, while a small change produces a different value.
Examples
- Create a SHA-256 checksum for a downloaded file.
- Compare two file hashes to detect accidental changes.
- Generate SHA-512 output for text without sending it to a server.
Frequently asked questions
Is my input uploaded?
No. This tool processes its input locally in your browser. Normal page requests do not include the contents you enter or select.
Is SHA-1 suitable for modern security?
No. SHA-1 is included for compatibility and legacy checksum comparison; use SHA-256 or stronger for modern security-sensitive work.
Will it work in every browser?
The tool uses modern browser APIs. Current Chromium, Firefox, and Safari releases provide the best support; the page displays a clear error when a required capability is unavailable.
