Verify a Downloaded File

Whenever I download something, I like to be very sure on the authenticity of the file. The only way to do this easily is by using a cryptographic hash. There are two main types. First is MD5, and the second is SHA1.
Requirements:
1. A computer.
2. 10 minutes to learn (the actual process is only 1 minute long.)
3. Internet connection
How to do it: (On Windows)
1. Download the file needing to be verified. (I am using a Linux ISO. This file can be anything, but you must be able to find a MD5 or SHA1 checksum on the page.)
http://mirrors.kernel.org/archlinux/...02.01-dual.iso
2. Download the MD5 or SHA1 checksum. (If it is next to the file, just keep the tab open.)
3. Open the command prompt
Press the Windows key and the “r” key at the same time. Type in “cmd” followed by enter. (This should work on all versions of Windows.)
4. Find the file you downloaded.
If you downloaded it in your Downloads folder, type in
If you downloaded it to your Desktop, replace “Downloads” with “Desktop”
If you did anything else, I assume you know where you downloaded it to.
5. Find the checksum of the file you downloaded.
If you used the MD5, then type this into the command prompt
For example I would type
If you used SHA1 replace the “-md5” with “-sha1”
6. Compare the output to the Checksum file or the website.
These two should be exactly the same. (Upper case and Lower case dOeSn'T matter.)
Simply put, just type in
or
then compare.

2. Download the MD5 or SHA1 checksum. (If it is next to the file, just keep the tab open.)
3. Open a terminal
Type Ctrl+Alt+F1 and then login. Or use your favorite terminal in X.
4. Find the file you downloaded
Type in “cd ~/Downloads” or the location of the file you just downloaded.
5. Find the checksum of the file you downloaded.
Type in
For example I would type
If you use SHA1 rather than MD5, replace md5sum with sha1sum.
6. Compare the output to the Checksum file or the website.

Sorry for the minimal amount of code. (There's not very much to it.)
