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.
Verification of the Monero binary files should be done prior to extracting, installing, or using the Monero software. This is the only way to ensure that you are using the official Monero binary. If you receive a fake binary (eg. phishing, MITM, etc.), following this guide will protect you from being tricked into using it.
