To protect the integrity of the binaries the Monero team provides a cryptographically signed list of all the [SHA256](https://en.wikipedia.org/wiki/SHA-2) hashes. If your downloaded binary has been tampered with it will be produce a [different hash](https://en.wikipedia.org/wiki/File_verification) than the one in the file.
On Windows or Mac, go to the [hashes file on getmonero.org]({{ site.baseurl_root }}/downloads/hashes.txt) and save the page as `hashes.txt` to your home directory.
