Hi.

Virtual Machine slows a code because it's being converted to the special instructions set and executed on an Enigma virtual processor, you must apply Virtual Machine only to the parts of your code that could be used to patch/crack your software, i.e. to a vital code parts that cracker shoulnd't see.

Themida got MUTATE_START and MUTATE_END it works well with loops, enigma doesn't have nothing similar?

You may use virtualization markers vm_begin/vm_end for the time critical parts of code. These markers are working much faster, however, provodes a lower security level.

Markers vm_risc_begin/vm_risc_end should be used for non time critical parts and they provide a maximum security level.

Looks like your loop is very time consuming, if even vm_marker does not provide enough speed for this part of the code, then it would be better just avoid to protect this loop. No any other ways to do that.

Yes exactly , i tried one day to protect a CRC32 function with VM markers :roll: , took an enternity to finish as the loop is too long i ended-up removing the markers there. :lol:
