The internet has brought many facilities in our life, but a general use increasingly born without a negative. As the spread of the Internet continues to be done as before, security issues are also increasing. It has become so easy for hackers to insert downloaded viruses into a file. In addition, the files may be corrupted or changed during download. In that case, how do you guarantee the integrity of the downloaded file? The answer is in the checksum.

Checksum is a code that consists of a series of characters provided by the site to ensure the integrity of the files downloaded from the site. To do this, download the file, run a local checksum on your computer, and compare it with the checksum specified on the site. Both values ​​are based on the fact that if the letters and letters match, the downloaded file was not modified in the download process, it is exactly the same as the intended font. On the other hand, if both checks do not match, it can be concluded that file integrity is corrupted, corrupted, or likely to be defective during download.

Some sites offer their own services to test the checksum of the file after download, and if you do not provide this tool? For Apple Mac users, here is their answer:

Terminal application for MAC users
The terminal application already exists on your Mac computer and can be used to check the local checksum of the downloaded file so that the online checksum generator or application help is not required. Just perform the following steps and generate a checksum for the purpose of comparison.

First, download the target file from the site to the Mac. For example, I downloaded a free WinMD 5 tool to check a checksum and a Mac terminal. They had a checksum available on my site that I could compare my sum of locally generated check.

Click the Launchpad on the Mac’s dock and select Terminal. Then the Terminal opens.
First, when you start, type the command ‘md 5’ in the terminal, press the spacebar and enter the path of the last downloaded file. If you’re worried, just type the full path or simply drag and drop the file into a terminal window to see the full path of the file right away. You can then start by pressing the Enter key on the terminal.

The terminal will immediately generate a checksum of the target file and display it so you can observe it. This is usually a series of letters and digits at the end.

Compare this locally generated checksum with the checksum on the file site and note the difference.


If there are no differences between the two strings of text, you are good. However, if both are different from each other, this means that the file has been corrupted or changed.

With Terminal on Mac, you can easily understand the integrity of the downloaded file in minutes. You no longer have to worry about the modified files that are on your system.
