I've been taking a look on an android game's folder called Wolf Online, and I've noticed the developers have chosen MD5 algorithm for the game security(I guess)
Can anyone help me to create a MD5 with "used key"? I've heard that MD5 can be read by machines only with a used key... but how do I know the hash's used key value? I've generated a MD5 hash with a site and then I tested it on the game, but it didn't work...
Here it is a screenshot of how it looks like: https://i.stack.imgur.com/6BStA.jpg
I want to change 15990 to another value, but I don't know how to generate the "encryption_check" nor "used_key"
