Hash Checker & Verifier
Compare original text against an existing hash to verify file integrity. Supports MD5, SHA-1, SHA-256, SHA-512.
Verify Hash
Ready to verify
Enter the original text and expected hash, select the algorithm, and click Verify Hash
What this tool does not do
- SHA hashes require a secure context (HTTPS) for the Web Crypto API.
- MD5 is computed locally with a JavaScript implementation and is always available.
- This tool checks hash equality only — it does not perform cryptographic signature verification.
How It Works
Enter data
Paste the original text and the hash you want to verify. Select the algorithm used.
Compute & compare
The tool computes the hash of your text and compares it to the provided hash.
See result
A clear match or mismatch result tells you whether the hashes are equal.
Frequently Asked Questions
How does hash checking work?
Enter the original text, paste the hash, select the algorithm, and click Verify. The tool computes the hash and compares it to the provided hash — case-insensitively.
Which hash algorithms are supported?
This tool supports MD5, SHA-1, SHA-256, and SHA-512. Select the algorithm that matches the hash you are verifying.
Is my data uploaded to a server?
No. All hash computation and comparison happens entirely in your browser. Your text and hashes never leave your device.
