Description

Our supplier claims he just developped a new and revolutionnary protector for our software’s DRM.

Here is a sample keygenme protected with its method.

I heard that no DRM is unbreakable. Would you be able to provide us an input leading to the 0x1234567890abcdef output?

Example: if the valid input is 0xaaaabbbbccccdddd, then the flag would be FCSC{0xaaaabbbbccccdddd} (hex string in lower case).
