About Hash Generator for Text and Files

A hash is a fixed-length string generated from input data, used mainly to verify that data hasn’t changed — the same input always produces the same hash, and even a tiny change to the input produces a completely different hash, making hashes useful for confirming a file downloaded correctly or matching data without storing the data itself.

This tool generates MD5, SHA-1, and SHA-256 hashes from text or an uploaded file. Worth knowing: MD5 and SHA-1 are both considered cryptographically broken for security purposes (though still fine for basic file-integrity checksums) — SHA-256 is the appropriate choice for anything where security genuinely matters.

Everything runs in your browser — relevant here specifically, since hashing is sometimes used to fingerprint or verify sensitive files, and having that process happen locally rather than passing through a third-party server is a meaningful difference for that use case.

Frequently Asked Questions

How to check a file hash on Windows?

In Command Prompt, run certutil -hashfile yourfile.ext SHA256, or in PowerShell run Get-FileHash yourfile.ext. Alternatively, open the File tab here, choose the file and compare the SHA-256 shown with the value the publisher lists. Hashing happens in your browser.

How to check a file hash on Mac?

In Terminal, run shasum -a 256 yourfile, or md5 yourfile for MD5. You can also pick the file on the File tab here and read the SHA-256 or MD5 result. The file is read locally by your browser and is not uploaded.

How to check a file hash in Linux?

Run sha256sum yourfile in a terminal, or md5sum and sha1sum for older checksums. If you prefer a browser, choose the file on the File tab here and compare the matching algorithm. The tool covers MD5, SHA-1, SHA-256, SHA-384 and SHA-512.

How to check a file hash value against the published one?

Hash the downloaded file with the same algorithm the publisher lists, then compare the two strings. A match means identical bytes, and any difference means the file changed or is corrupt. The whole file is loaded into memory, so very large files may be slow.
