PHP software encryption

Is there an easy way to encrypt a php script without having to worry if a hosting account has zend or iono cube installed

I have had issues with the iono script and cannot find anything comparable, is there anything on the market that is reasonable but doesn't require server side installs?

It would also need to work on linux and windows based servers

    Hiiii.....

    There is a php encrypter called SourceGuardian Pro......
    This encrypter does not need any server side instalation..
    I hope it will solve your purpose.

      Hello,

      Any code can be cracked with a smart enough person. I would obfuscate your code, it is not fool proof, but definitely makes it a lot harder and you won't need all that extra stuff. There is a software out there that some of my clients use. I will try to find out for you and let you know.

    I was told that there are programs designed to read any obfuscation? of a script and return it in easy to read language so wouldn't encryption be the best way to go?

      Like I said before.....anything can be decrypted if you are smart enough and have the patience. To me it is a flip of a coin, you can go either way. Here is that link......obfusc[dot]com.....I don't have enough posts so I can't put in the actual link.

        I have heard good things about SourceGuardian for what you're asking about. But the bottom line is nothing available is 100% uncrackable if the person trying to do it has his/her mind set on getting to your code.

        It's like any lock ... it only keeps out the honest!

        I hope this helps!

          To be honest it's a tradeoff do what you can without compromising portability and usability, what that probably means is obfuscation is the way to go rather than encryption because encryption requires too much infrastructure.

    If you require simple encryption, I recommend you to try phplockit.

    I once sold a php script and used ioncube with awesome success. Not even 1% off the customers needed support for the installation and barely anyone ever didnt got it to work because of his hosting (most companies would even set you up with ioncube) ... I really recommend to either go this route or completely forget about security/warez at all

      I'd like to hear from more folks who have used this and how they feel about it.

      Thanks in advance for your time.

    I'm pretty sure w/ ioncube you don't have to worry about the server setup like you do w/ zend optimizer. Ioncube does crazy good obfuscation and no one will want to mess w/ it unless its a killer product... like selling millions good.

      With an IonCube-protected script, I needed to get the correct version of the IonCube shared libraries, install them on my server, and alter my httpd.conf (I could have used .htaccess, of course) before they would work.

      This was not terribly difficult, but someone less technical might find it mystifying.

    Our company uses Ioncube to encrypt our $500+ software and it does a pretty good job, very few customers have problems with Ioncube now, but it wasn't that way in 2006.

    Encrypting with Zend is useless as there is software that will decrypt the file at a touch of a button, people still have to spend days decrypting Ioncube files and even then they have to try and reverse engineer the original code.

    That said, we've seen a number of dedicated people get together and decrypt our products, we simply change all the file structure and then they have to start all over again

    Ioncube needs to be updated though, it's been a while.

      As mentioned it's a lot better these days than it used to be with regard to Ioncube support being installed on a server but I still run into the issue on occasion.

      This is one of my problems using it as I feel I have to distribute the runtime files with my script and I'd rather not.

      I do like Ioncube and look forward to the day when all servers will have it available and we can drop distributing the runtime files with the script.

      I did download the PHP Lockit trial and it looks pretty good but would really like to hear from those who have used it for a while.

    Code Eclipse provides free obfuscation:

    Code Eclipse - PHP Obfuscator

    Sure, it can be cracked, but as mentioned above, so can anything pretty much.

      I have to admit that's one thing I like so far in PHP Lockit ... it's does encryption and obfuscation

        It depends how important protecting your source code really is and how important it is for your clients to have a trouble free installation? Products like PHP Lockit do not require any loaders or anything called by the php interpreter at runtime. The encryption in these types of products are NOT one-way, as they rely on functions within php to hide the source! Even somebody with novice programming experience would not find it difficult to reveal the source code. Then you have TRUE one-way encryption products from the likes of Zend, ionCube and SourceGuardian that do require loaders. These products encrypt your scripts to native bytecode (machine readable code) which is why they require their each and respective proprietary loaders! Contrary to popular belief they CANNOT be reverse engineered! However, php itself is open source so any experienced programmer could reengineer your scripts to a human readable state by comparing the opcodes against a logical translation table to basically rewrite the functionality of your scripts on the fly. The trade off for you is how difficult do you want to make it for any would be cracker or how difficult do you want to make it for your clients?

    Disclaimer: it is my product:
    ZenCrypt.
    Specifically designed to avoid issues with hosting accounts. I owned license for IonCube and had too many complaints from customers. I use zencrypt now for my own plugins. Plus it allows you to encrypt parts of code (like footer, linkbacks, or license verification code). Demo samples included.
