Hash Generator
About this Tool
Create a cryptographic hash (or "digest") of any text using the secure SHA (Secure Hash Algorithm) family. This tool uses the native Web Crypto API in your browser for enhanced security, solving needs for data integrity checks or password storage.
How does it work? It encodes text to bytes, then applies SHA via subtle.digest(), outputting hex.
- Enter the text you want to hash into the input area.
- Select the desired SHA algorithm (SHA-1, SHA-256, or SHA-512).
- Click the "Generate" button.
- The resulting hexadecimal hash will be displayed in the output area.
- Verifying file integrity with checksums.
- Hashing passwords before storage.
- Generating unique keys from strings.
- Supports SHA-1, SHA-256, and SHA-512 algorithms.
- Powered by the secure, built-in Web Crypto API.
- No server interaction ensures your input data remains private.
Hashing maps data to fixed-size values, one-way and collision-resistant. SHA is from NIST, with SHA-256/512 being secure for most uses, used in blockchain, SSL, etc.
Is SHA-1 secure?
No, use for legacy; prefer SHA-256.
Can I hash files?
This is text-based; file hashing needs upload.
What's hex output?
Base16 representation of the binary hash.
All calculations and data processing for this tool are performed locally in your browser. We do not send any of your data to our servers, ensuring your information remains private and secure.
