Hash Checker & Verifier
Compare original text against an existing hash to verify file integrity. Supports MD5, SHA-1, SHA-256, SHA-512. Free, private, browser-based.
No sign-up • No server uploads • 100% browser-based
How It Works
1 Enter Data
Paste the original text and the hash you want to verify. Select the algorithm used to create the original hash.
2 Compute & Compare
The tool computes the hash of your text using the selected algorithm and compares it to the provided hash.
3 See the Result
A clear green check or red cross tells you whether the hashes match. The computed hash is shown for your reference.
Frequently Asked Questions
How does hash checking work?
Enter the original text, paste the hash you want to verify, select the algorithm, and click Verify. The tool computes the hash of your text 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.
Can I verify a file hash?
You can paste the text content of a file and compare its hash. For large files, compute the hash on your system and paste both the original text and the expected hash for comparison.
