What does this tool do?
Hash Compare computes the MD5, SHA-256, or SHA-512 digest of the text you enter and checks it against a known hash you already have. It is a handy integrity-verification tool for anyone who wants to confirm that a file or piece of text has not been altered. All hashing runs in your browser.
How to use it
- Choose the required options or length.
- Generate the secure result.
- Copy and store the result safely.
Three algorithms and integrity checking
Choose between MD5, SHA-256, and SHA-512; the SHA variants use the browser's built-in Web Crypto API. Enter your text and press 'Compute' to generate the digest. Then paste the hash you expect into the compare field, and the tool checks the two values case-insensitively, showing a green confirmation on a match and a red warning when they differ. This lets you tell whether a downloaded file matches the checksum a publisher announced.
When to use it
It is useful for comparing a downloaded program against the SHA-256 value a vendor provides, checking whether a snippet of text has changed, or verifying an expected signature digest for an API request. MD5 is fine for a quick checksum but is weak for security; prefer SHA-256 or SHA-512 when you need a real integrity guarantee rather than a casual comparison.
Frequently asked questions
Is the comparison case-sensitive?
No. The pasted hash is trimmed and both values are lowercased before comparison, so it does not matter whether the hash is written in upper or lower case.
Is MD5 still secure?
MD5 is broken against collisions and should not be used for security. It is only suitable for a fast, non-critical integrity check; use SHA-256 or SHA-512 for serious verification.
Can I upload a file?
This tool hashes text input. To verify a file's contents, you can paste its content into the text area to compute and compare the digest.
