Professional File Hash Verifier
Features
- Compute SHA-1, SHA-256, SHA-384, SHA-512 hashes using the browser's WebCrypto SubtleCrypto.digest
- Drag-and-drop file or paste text — handles both modes
- Side-by-side compare against an expected hash with case-insensitive matching
- MD5 is NOT supported — WebCrypto doesn't provide it (and it shouldn't be used for integrity / security anymore)
- Runs entirely in your browser; files never leave your machine
How to use
- Enter your input data in the provided field.
- Configure any options as needed.
- View the results instantly and copy or download the output.
Tips & Best Practices
- Use SHA-256 for general-purpose integrity checking (matches the hashes most projects publish alongside downloads).
- SHA-1 is deprecated for cryptographic use (collision attacks exist), but is still valid for non-security integrity checks.
- MD5 is broken — don't use it for trust decisions. This tool deliberately omits it.
- File hashing runs in-browser via the File API. Files of any size work but very large files (>1 GB) may pause the UI while the hash computes.
- Hash comparison is case-insensitive — paste the expected value in whatever case the publisher used.
