Applies to: Zend Guard Security Summary People are often concerned about various technologies that exist that claim to reverse the protection provided by Zend Guard. We thought it was important to address it here. Zend Guard provides some of the best technology available to protect applications from reverse engineering but Zend has never claimed that Zend Guard is impervious to reverse engineering. Given enough time and a determined hacker, any encoding technology can be broken. This has been true since the first hacker decompiled binary machine code. Technical Aspects The first level of protection is encoding.

DeZender is the software that specially used for to decompile/decode PHP files encoded by Zend Encoder/SafeGuard, ionCube, or SourceGuardian. It mainly use cryptanalysis, decompressing and decompiling technology to decode an encoded PHP file into readable, executable PHP source code.

During encoding the PHP source code is converted to a binary format that is used at runtime by the PHP engine in conjunction with Zend Loader. Only the encoded files are deployed and your original source code remains secured which prevents your application from being read by the casual observer. Unfortunately technologies do exist that will allow encoded files to be decoded. Due to the open source nature of PHP there is virtually no way to prevent a person from hacking at the PHP engine code to intercept the bytecode after it has been decoded for execution. Kyocera Mita Admin Manager Download. The second level of protection is obfuscation. During obfuscation the encoded files are further processed to obscure the names of classes, methods, variables and other items in the code.

Obfuscation of names cannot be automatically reversed without a key that only exists on your system. However, it is still possible from someone willing to spend enough time to figure out what is going. It's a lot harder with variable names like XsddR2245as and class names like wwEgg33k55jsc but it is not impossible.

The last protection feature is licensing, although it does not touch or alter the PHP source or entities, but rather limits execution to bind with a license file, signing the PHP scripts according to a specific product name, which also appears in the license file. It makes another level, or layer of code protection, by making sure that whomever for a specific application and license from a specific software vendor, would be able to run the protected application. This reduces the number of random people who can run your code and try to hack into it's source, since you normally know exactly who gets a license to your application, and can limit its expiration and other aspects, such as IP or Host Id for example. Conclusion So while Zend Guard can make the job of someone wanting to steal your code/IP harder, ultimately your protection has to be provided by your end user license agreement (EULA) and whatever remedies it provides for you and your customers in the event of a legal dispute.

Hey guys, We all have heard of IonCube and Zend Encoder, but they cost way too much. Being in the php line field, i was able to figure out how we can provide a service for free for all the folks that are looking for a good high encrypted php encoder. Digging Deeper With The Dfx Pdf Printer more. Well here it is, all for free: FreePHPEncoder.com is a free online PHP code encryption and obfuscation service that allows users to protect their PHP file source code from being viewed. PHPEnc's encryption service is very simple to use, simply upload the file you wish to encrypt and download the encrypted copy of the file. We're constantly upgrading the system to provide better encoding features as well as the ability to encode more files. How to use it? 1) Upload the file(s) you wish to encode 2) Click the 'ENCODE!'

Button and download your encoded file. 3) Download the decoder PHP file. 4) Upload the decoder file to the SAME directory as your encoded file in your web.

5) Run your encoded file like a normal PHP file * Decoder file paths can be changed in encoded files to support multiple files. * Decoder file must be uploaded in binary mode. Check it out here remember its free as well as good as Zend Encoder! Hope you guys enjoy it and what it does!
