encrypting/password protect a .crx file

[dashman]

i'm writing a commercial extension and would like to
protect it.

i know minifying the javascript is an option - but that
can easily be unminified given enough time.

any suggestions?

there is no effective method to do that, even average JS programmer with strong determination can get your code no matter what kind of mess you will leave in your code. Best protection effects you will get when logic of your extension will take place inside your server somewhere on the web.

year an a half after....

* is still impossible to protect code of extensions? is not any option to sign the crx file or something like that. Is it possible to protect small at least small parts of the code containing the sensitive stuff?

* supposing that a payed service is created, this would mean that there is not way to prevent any user editing the code and bypassing the payment verification source code. Is that correct? Whic is the approach to integrate a payment mechanism in an extension?

* I need to package several extensions so I would like to do it programmatically. However, I had some issues working with 

chrome.exe --pack-extension=c:\myext --pack-extension-key=c:\myext.pe

is there any small java jar or classes (from Chromium core) which allows packaging an extension programmatically? (I guess that chrome.exe should invoke some Java code in Chromium)

Share your ideas please. Thank.

As far as I can see there is not a Java tool to package Chrome extensions.

http://stackoverflow.com/questions/3196615/how-to-create-chrome-crx-file-programatically-preferrably-in-java

only a ruby and a bash programs. But on the other hand, I tried to package programmatically as said here 

chrome.exe --pack-extension=c:\myext --pack-extension-key=c:\myext.pem (copied from previous linked page)

but running this the command in Win7 just does nothing.

I also:

* killed all my Chrome windows since there was a bug as said here

* tried / and \ as file separators,

* ended the path to the directory (?) with and without / 

* tried in the chrome folder just in case any other file is needed (in 'Path' env var)

and still nothing happens. Nothing created, no messages. I am running Chrome Version 26.0.1410.64 beta-m on Win7.

Does anyone know the trick?

Thanks

happily I upgraded today to release Version 27.0.1453.93 beta-m and packaging extensions with chrome.exe is working in this release

For the syntax (which is now working for me in Version 27.0.1453.93 beta-m),

chrome.exe --pack-extension=c:\myext --pack-extension-key=c:\myext.pem

does anyone know how to specify the output directory? I intend to programmatically generate several crx in bulk by only changing a config file from one to the other.

None of arguments here looks specific for this purpose
