It's a one way conversion, so the same data in will present the same data out, however from the data out, you cannot decipher what data went in. Therefor MD5 is used for 2 perposes, 1, to create data "stamps" to ensure that what you have download is the correct, & unaltered data, & 2 is to create a basic level of encryption for data transmission. So in your situation it is being used for the 1st reason I listed. They are providing you with the data signature, so before you uncompress (& use) the downloaded file, you can check it with MD5 to assure that you are not downloading an altered release.
