Verification
Hash Compare Tool
Paste two hash values to check if they are identical.
The Hash Compare Tool checks whether two hash strings are identical after optional normalization. It helps you verify integrity checks, compare downloaded file hashes, or validate that a generated hash matches an expected value.

What this tool does
The Hash Compare Tool checks whether two hash strings are identical after optional normalization. It helps you verify integrity checks, compare downloaded file hashes, or validate that a generated hash matches an expected value. The tool displays match status, normalized values, and lengths to catch subtle differences.
When to use this tool
Use it when you receive a reference hash from a vendor, compare outputs across systems, or confirm that a copy of a file has not changed. If you need to generate a fresh hash before comparing, use Hash Generator first, then paste the results here for verification.
How it works
The tool optionally trims whitespace and normalizes case, then compares the two strings character by character. It also reports the length of each input so you can spot obvious format mismatches. All processing happens in your browser, and no values are sent to a server.
Example use case
You download a release package that includes a SHA-256 hash. Generate a hash of your downloaded file with the Hash Generator, paste both values here, and confirm they match. If the lengths are different, you know the hash type or input is inconsistent before you ship the file to production.
Use cases
- Verify a downloaded checksum against a vendor hash.
- Compare hashes generated in different environments.
- Check file integrity after a transfer.
Notes & limitations
This tool does not determine which hashing algorithm was used; it only compares strings. Case-insensitive comparison is helpful for hex-encoded hashes, but base64 hashes are case-sensitive and should be compared with case sensitivity enabled. Always ensure you are comparing the same algorithm and input data.
Hashes copied from terminals or emails sometimes include trailing newline characters. Use the trim option to remove accidental whitespace, but avoid trimming if you are comparing exact binary-to-text outputs. When in doubt, regenerate both hashes from the original source and compare fresh values.
Length mismatches usually indicate different algorithms or encoding formats, so check the source documentation.
