Hash Verifier
Drop or select any file to compute its MD5, SHA-256, or SHA-512 checksum in your browser — no bytes are uploaded to a server, so sensitive documents stay on your device. Optionally paste an expected hash to get an instant match or mismatch verdict. Useful for verifying digitally-signed government documents, application attachments, and downloaded exam admit cards to confirm they have not been altered in transit. SHA-256 is ticked by default per NIST FIPS 180-4 recommendations; MD5 is included for compatibility with older systems that still publish MD5 checksums.

Verify Against Expected Hash
Privacy: No file data leaves your device. SHA-256 and SHA-512 use the browser's built-in Web Crypto API (NIST FIPS 180-4). MD5 is computed locally via a pure-JS implementation (RFC 1321). MD5 is provided for compatibility only — use SHA-256 or SHA-512 for security-sensitive verification.
