• As it using zepto.js v1.1.2, you need modern browser to use b374k shell. See browser support on zepto.js website http://zeptojs.com/
• Responsibility of what you do with this shell

Installation :
Download b374k.php (default password : b374k), edit and change password and upload b374k.php to your server, password is in sha1(md5()) format. Or create your own b374k.php, explained below

Customize :
After finished doing editing with files, upload index.php, base, module, theme and all files inside it to a server
Using Web Browser :
Open index.php in your browser, quick run will only run the shell. Use packer to pack all files into single PHP file. Set all the options available and the output file will be in the same directory as index.php
Using Console :

$ php -f index.php
b374k shell packer 0.4

options :
        -o filename                             save as filename
        -p password                             protect with password
        -t theme                                theme to use
        -m modules                              modules to pack separated by comma
        -s                                      strip comments and whitespaces
        -b                                      encode with base64
        -z [no|gzdeflate|gzencode|gzcompress]   compression (use only with -b)
        -c [0-9]                                level of compression
        -l                                      list available modules
        -k                                      list available themes

example :

$ php -f index.php -- -o myShell.php -p myPassword -s -b -z gzcompress -c 9

Don't forget to delete index.php, base, module, theme and all files inside it after you finished. Because it is not protected with password so it can be a security threat to your server
