Hi to everyone, I'm new to the forum, but use openpli and I thought about writing here

i'm trying to make a plugin, just i would like to compile it in .so to protect the source code,

can someone help me?

thanks for the answer, I saw but you did not solve it...how do you create the file.so?

[WanWizard]

You can't compile python into a binary. You need to write your plugin in C++ with a python loader so it integrates into Enigma.

 

If however you want this to obscure your intentions, then don't bother, a binary file can be disected too.

hello, thank you for the answer,

I proceed this way, convert from python to C with cython

"cython -a file.py " in this way I get the file so file.c

now 

ggc -shared -pthread -fPIC -fwrapv -02 -Wall -fno-strict -aliasing \

-I/usr/include/python2.7 -o file.so file.c
like this i have the file.so, but not work in enigma2
he tells me you can not open this file

No, because that would be in violation of Enigma2's GPL license.

[hacksat]

also openpli has in its file.so
I just need to know how I can make it read to enigma2 ... please

I guess you didn't read the thread mfaraj57 linked..

Security through obscurity is no security at all.
However, library written in the C sometimes is needed because of performance.

For example here:
https://github.com/s...r/iptvsubparser

is module written by me to speed up parsing external subtitles.

There is simple make.sh written in bash which call cross compiler directly .
I think it is easy to understand and learn how it is working from A to Z.

Obfuscating is futile anyway. Don't bother.

thanks for the reply, I was reading your answer now

Hello, thanks for the answer

are you saying that even a file that is compiled as file.so is readable?

[ozzsurf]

.so  file easy to read with readelf

[hacksat]

.so file easy to read with readelf

I knew that at most you could have info on the file.so with readelf but not that you could read the entire content ... a decompilation?

[WanWizard]

You can strace it, you can decompile it, you can even step through it at machine code level if you really want to.

does anyone know how to decompile the file.so?

[WanWizard]

Define anyone? My dad, no probably not. Anyone who has a vested interest in finding out what you are up to, yes, probably. Or they find someone who can.

ahhahahah sure, i just want to learn, i do not know how to do it and i would like to know it

[Erik Slagter]

We get this request quite often and also often is turns out that a username and password for an illegal subscriber service need to be hidden. This is a practice we're not quite fond of, for various reasons. So to get any support, you'd better have at least a good reason to do so.

[hacksat]

No, it does not concern any password for illegal purposes,

it's just a matter of making reading a python as easy as possible,

that's why I want to learn how to create files.so running on the box enigam2 and figuring out how to decompile (i could not do until yesterday)

[mirakels]

if your objective is 'learning' then why take the detour via an engima2 box?

Why not just develop an .so for your developper machine (assuming you use a linux machine) and play around with that. 

And when you have questions about how to decompile,  obfuscate code, hide code you're better of on programming forums.

Here we work on improving the user experience for satellite receivers with open source in mind. So everyone here should not be eager to invest time in creating binary only stuff.
