Hi,

I was wondering, what are, if any, the interactions between the files encoded with the new IonCube 9 and loaded with the PHP 7 Loaders, and the OpCache and AST extensions of PHP?

Will it be possible to cache bytecode after decoding by IonCube using OpCache?

Will it be possible to dump the AST for an encoded file?

Due to the way our solution works and the degree of protection that it offers, it's not possible to cache bytecode with opcache.

Thanks for this first answer, however, what about my second question, that is, its possible interaction with AST?

If it is possible to get the Abstract Syntax Tree of an encoded file, it'll be possible to actually decode encrypted files...

There is no AST in an encoded file, so no Smile Furthermore, and unlike other solutions that use static keys, if you use the dynamic keys feature, parts of an application can be encrypted and there is no decryption key stored anywhere to be discovered.
