My Friend recommended this Super Awesome game The_Elder_Scrolls_V_Skyrim.zip and obviously it was downloaded from a random website from the internet ( some ripoff of the OceanOfGames.com ). The contents of the The_Elder_Scrolls_V_Skyrim.zip are as follows : -

Challenge Description:
Written by: ItzSomebody
Description:
Keith made a cool license-checking program but he forgot the flag he used to create the key! To make matters worse, he lost the source code and stripped the binary for his license-generator program. Can you help Keith recover his flag? All he knows is:
- The license key is 4-EZF2M-7O5F4-V9P7O-EVFDP-E4VDO-O
- He put his name (in the form of ‘k3ith’) as the first part of the flag
- There are 3 underscores
- The flag is in the format hsctf{}
- The flag doesn’t have random character sequences (you should be able to read the
- entire flag easily).
- The flag only contains lowercase English letters and numbers.
- The generator might produce the same keys for different inputs because Keith was too lazy to write the algorithm properly.
