Hash codes are like a file’s “digital signature.” When a hash is generated from a file, a short and unique code is created that represents the file’s content. If the content is altered even slightly, the resulting hash will be completely different. That is why hash codes are extremely useful for verifying the integrity and reliability of files.

In addition to verifying integrity, hash codes are also used to confirm a file’s originality. Typically, the original sender or the website providing the file should display the hash code before the download, so the user can compare it with the hash of the downloaded file. This ensures that the downloaded file is original and has not been tampered with.

Likewise, when someone sends you a file (of any kind), it is advisable that they also include the hash code. This allows you to verify the file’s integrity and origin, and ensures that there is no risk of viruses or malware.

By comparing the original hash to that of a downloaded file, we can determine whether the file has been altered or infected. This is especially important when receiving software, critical documents, or any information that needs to be secured.

In summary: hash codes help us confirm that a file is trustworthy, verify its originality, and increase security.
