Python Programming!

I have tried Python earlier, but its syntax didn’t make sense to me. Several weeks later, I wanted write a small app, so, I thought, why not try to write it in Python.. Just give it a try… So, I start writing the app in Python, it took longer than it should have, but it was done! Now, I can program in Python. I am so happy that I have finished writing my app in Python. Looks like Python has been added to my portfolio of programming languages.

ZenCrypt — PHP Encoder

Last night, I was searching the internet for PHP Encoders, I always knew that ZendGuard and IONCUBE are the best. However, I thought of giving others a chance. While searching I came across ZenCrypt. One of the good things about it that it doesn’t need a loader on the server-side. Thus, the scripts are self-decodable. But this makes it easy to decrypt. On thier website, they have two scripts. One is the source, and the other is the encoded script.

My Attempt to understand its way of encoding to see if it worth the USD45.

Source PHP Code:

$resulted_number = ZEN_encrypt ($encrypted_number);
echo "\nEncrypted number=$resulted_number";
$resulted_number = ZEN_decrypt ($resulted_number);
echo "\nDecrypted number=$resulted_number";

// This part will be encoded and moved above (in between PHP_INSERT tags).

{
return ($input+5432);
}

function ZEN_decrypt ($input)
{
return ($input-5432);

Conclusion:

What I see that it doesn’t worth the the USD45. Maybe if it was encoded with ZendGuard or ionCube and produces a file that requires a PHP Loader. Just like PHPCipher.
However, from this attempt. I thought that I will write my own encoder. It will be using the same method, however, the output will be encoded in both ZendGuard and ionCube. Stay tuned!

A new year arrives and new projects to come

A new year arrived, and new projects are arriving… My friend Marwan and myself started having several projects to be developed for the Maemo powered devices. However, after discussion today, we have agreed on developing stuff to be cross platform. Most of our development well be in Python GTK.

The agreement is that Marwan will do most of the development, I will be maintaining the projects. I will be responsible of the packaging and bug fixing and some development. Marwan will be doing the core of the applications.

We will be registering a new domain and it will be dedicated for our joint projects. We have lots of ideas, so wish us luck!!
