PHP Shield - The PHP Encoder
Overview

ª«
    phpSHIELD protects your PHP Source Code
    with a powerful, easy to use encoder, which
    creates a native bytecode version of the script
    and then encrypts it.
ª«
    Encrypted and protected code works under
    Windows, Linux, Mac OS X, FreeBSD, NetBSD,
    OpenBSD, OpenSolaris.
Overview

ª«
    Some other PHP encoding systems do not use
    bytecode and it is very easy to reverse
    engineer their protected scripts back to the
    original source code. With bytecode encryption,
    it is never possible to do this as the original
    sourcecode has been completely removed from
    the protected file.
Protected script loaders

ª«
    Protected script loaders are dynamically loaded
    PHP extensions which load the protected script,
ª«
    decrypt it and then run the bytecode. The
    Source code is never restored at any time,
    even in memory.
ª«
    There are different versions of the loaders
    available for different operating systems and
    PHP installations.
ª«
    phpSHIELD protected script loaders may also
    be installed manually in to a php.ini file
ª«
    example, if automatic loading is not supported
    or if faster performance is required.
ª«
    Protected Script Loaders will be updated
    periodically and the latest loaders are always
    freely available
Loader filename structure

ª«
    The following provides an overview of the
    loader naming conventions:
ª«
    ixed.X.Y.Zts.os
ª«
    X.Y - major PHP version number (4.3 for 4.3.x,
    5.0 for 5.0.x, 5.1 for 5.1.x, 5.2 for 5.2.x)
ª«
    Z - minor PHP version number (2 for 5.0.2) This
    is optional and most loaders DOES NOT have
    the minor
ª«
    ixed.4.3.lin - for all PHP 4.3.x versions
ª«
    ixed.5.0.0.lin - for PHP 5.0.0 only
ª«
    ixed.5.0.1.lin - for PHP 5.0.1 only
ª«
    ixed.5.0.2.lin - for PHP 5.0.2 only
ª«
    ixed.5.0.lin - for all PHP 5.0.3+ versions and
    higher
ª«
    ixed.5.1.lin - for all PHP 5.1 versions and higher
ª«
    ixed.5.2.lin - for all PHP 5.2 versions and higher
ª«
    ixed.5.3.lin - for all PHP 5.3 versions and higher
Encoded scripts modification

ª«
    Encoded scripts are protected against
    modification. Please DO NOT MODIFY any
    single byte in the
ª«
    encoded scripts or you will get an error
    executing them.
