At some point in your programming career, you will probably need to use an MD5 hash. Most likely just to get the hash for a password.<\/p>\n
One of the simplest ways is to use groovy. Here is the code. Don’t even need to put it in the download section. Just copy the code to a file and run it.<\/p>\n
