IonCube is a very well-known loader used to protect PHP source code. I will decompile the source code from the obfuscated/encrypted files you provide.
Pricing - per file that needs to be decompiled with a maximum charge equivalent to 500 files. If your script is 501 or more files then you will buy 500 files, but all of the files will be decompiled. Do not try to combine different scripts into one order, I will see it and you will be charged for each script separately.
What kind of files can be decompiled?
ionCube
NuSphere PhpExpress
Zend Optimizer
If I am unable to decompile your files then I will refund your money. Understand, I cannot guarantee your script will run because ultimately that is dependent on the script itself. However, you will have access to the raw source code.
