Hash Generator
Compute cryptographic hashes for text or files. Supports SHA-1, SHA-256, and SHA-512. Useful for verifying file integrity and checking checksums.
How It Works
Enter text or upload a file
Type or paste text, or upload a file to compute its hash.
View all hashes
SHA-1, SHA-256, and SHA-512 hashes are computed simultaneously and displayed together.
Copy any hash
Click to copy any individual hash value to your clipboard for verification or storage.
Frequently Asked Questions
Which hash algorithms are supported?
The tool computes SHA-1, SHA-256, and SHA-512 hashes simultaneously using the Web Crypto API. All three are displayed at once so you can use whichever you need.
Is my data sent to a server?
No. All hash computation happens in your browser using the Web Crypto API. Your text and files never leave your device.
Can I hash files?
Yes. Upload any file and the tool will compute all hash values. This is useful for verifying downloads and checking file integrity.
Which hash algorithm should I use?
SHA-256 is recommended for most use cases including file verification and checksums. SHA-512 provides a longer hash for additional security. SHA-1 is supported for legacy compatibility but is no longer considered secure for cryptographic purposes.
