algoritm to encrypt a network server

we are science of glory and save the world


salam people power
selamat membaca kawan


ini adalah kode yang saya dapat dan saya anlisa kemudian saya tambahkan sedikit untuk using systemnya agar lebih efisien aja sihhhh :D :)
nah kalau teman teman mau copy script silahkan
nih scriptnya:
 /*
*
* MAFIAWARE
* Algorithm from HT, with C Sources
* Encrypt with AES256
