Форум АНТИЧАТ - ionCube Loader

привет нужно разшифровать ionCube Loader
есть какие то варианты? скрипты? я знаю что енкодинг сделан с в последовности частей алгоритма.. тоесть просто проги с копочкой крекнуть небывает.. есть связка скриптов которая по очереди с выводом и результатом твоих ледующих действий

Цитата:

1.Cut first 0xE bytes
<?php //00337{0x0A}
if(!extension_loaded('ionCube Loader')){$__oc=strtolower(substr(php_uname(),0,3) );$__ln='/i

2. cmp with "<?php //0"
3. HeaderSize=Get Number 0x0337
3.1 seek to HeaderSize+Digits

4. Get First 4 Byte
4+oV5E3tizCOGmZa...
"4+oV"
while Cmp with
0xDEADC0DE, 0x3FBC2883, 0x882BC103, 0x0217582F, 0x149FEC13, 0x67A6BF45, 0x9EB67AC2
"0y4h", "BrWN", "4+oV", "HR+c", "mdgs"
loop next byte and counter< 0x40

6.Decode whole block with custim Base64 decoder
Speciality
Uses this Alphabet:
0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmn opqrstuvwxyz+/=
ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwx yz0123456789+/
instead of ^this one, which is the standard for Base64
