Hash Generator & Checker
Compute MD5/SHA hashes of any text and compare them against an expected hash to verify integrity.
SHA-256 Of Your Input
What Is the Hash Generator & Checker?
The Hash Generator & Checker computes an MD5, SHA-1, SHA-256, SHA-384 or SHA-512 hash of your input and compares it, case-insensitively, against a hash you paste in. It gives an instant match / no-match result, making it perfect for verifying that a download, message or file hasn't been altered. All hashing runs locally in your browser.
How It Works
Pick an algorithm, enter or paste your text, then paste the expected hash. The tool computes the hash of your input and tells you whether the two match. Whitespace and letter case are ignored when comparing.
When to Use It
Use it to verify a file's published checksum, confirm that two systems produce the same hash, validate data integrity after transfer, or check that a value matches a stored fingerprint.
Frequently Asked Questions
- Which algorithms are supported?
- MD5, SHA-1, SHA-256, SHA-384 and SHA-512. Use SHA-256 or stronger for security; MD5 and SHA-1 are fine only for non-security checksums.
- Is the comparison case-sensitive?
- No. Hashes are compared case-insensitively and surrounding whitespace is ignored, so a hash copied in upper or lower case still matches.
- Is my input private?
- Yes. Hashing uses your browser's built-in crypto and nothing is uploaded to a server.
