	Engine


Hi,

TAPiON engine was developed to avoid code detection (shellcode/whatever).

The engine can create unical decryptor, encrypt original data and 
decrypt it on the fly (while code executes).


MAIN FEATURES:

#  decryption key based on randomly generated decryptor (attacker
    breakpoint insertion will cause invalid decryption)

#  decryption based on CPU time (selected randomly) - anti emulator
    code.

#  RDTSC / coprocessor instructions usage - anit emulator code.

#  random step of block xoring

#  random step of key increasing

#  random registers usage

#  multiple instructions variants

#  block swapping

#  garbage engine (normal instructions / coprocessor instructions)

#  block swapping

#  random decryptor size

#  multiple decryptor layers generation
