LCTF 2017: Nuclear Bomb

The name is "nuclear bomb", because it is designed as a CUDA-acclelerated program on Nvidia CUDA cards.

Basically, the program will use input to get a long random cipher, do some bit operations and subititles using GPU, and compare with preset table.

This is really easy, because only a first few bytes is used. And once you have got the first rand it get, you can get the original seed out, which can be concatenated into a long flag.

See ctf_output/readme.txt(in chinese) for more info.

This contest might be the last time for me, to write a challenge for CTF games. Thanks for XDSEC, and thanks for all my friends.

Happy hacking!
