MD5 means Message Digest 5, a cryptographic hashing algorithm to check the integrity of files. SHA2 is the cryptographic replacement in secure applications.

MD5 is used a lot to show the integrity of a download. You run md5sum on your download and compare it with the number on the website. If it doesn't match, then either that file has been hacked or the download didn't complete properly. If you are the programmer you'd include the hash on your website with your download so users can compare the download.

and is it so important to check it?

you need to decide that for yourself. it is just a way to make sure the file you have is the same as the one the dev created, down to the last bit. checks for bad download, wrong version, modified file etc... bad download probably being the most important one.

can you explain me stepby step, please?

[Guest kendon]

you don't need to check it unless you have problems. if you still feel the need to do so i am sure google will be of tremendous help.
