1.什么是Zend Guard?

Zend Guard是PHP市场上第一个保护PHP知识产权的代码加密解决方案和电子许可管理方案。Zend Guard通过原始代码加密以及限制分发没有授权的软件来实现软件的最大化收益。

支持的操作系统:
Linux x86
Windows x86 2000 / XP / 2003 / Vista (仅支持32位)
Mac OS X 10.4, 10.5

支持的PHP版本:
4.2.x 到5.2.x

3.Zend Guard与Zend Optimizer的关系及兼容性

Zend Guard加密后的PHP源程序需要环境中安装Zend Optimizer才可以运行,同时Zend Optimizer在加密的过程中也可以实现优化代码的作用。

以下为各个Zend Guard版本与Zend Optimizer各版本的对应关系:

Zend Encoder / SafeGuard 3.1 (HOST ID) - Optimizer 2.5.x
Zend Encoder / SafeGuard 3.6 (Zend ID) - Optimizer 2.5.2
Zend Guard 4.x (Basic Encoding) - Optimizer 2.6.x
Zend Guard 5.0 (PHP 4, Basic Encoding) - Optimizer 2.6.x
Zend Guard 4.x (Full Obfuscation) - Optimizer 3.0.x
Zend Guard 5.0 (PHP 4, Full Obfuscation) - Optimizer 3.0.x
Zend Guard 5.0 (PHP 5, All Encoding) - Optimizer 3.3.x

3.如何试用Zend Guard?

可以从以下页面下载Zend Guard最新的5.0.1并安装试用:

注意:试用版本不限使用期限,但是加密后的PHP源代码会在14天后过期;如果同时为某个程序加密同时生成许可文件,该许可文件将在3天后过期,所以为了您的利益,我们提醒您尽快购买正式的Guard许可。

4.如何安装Zend Guard?

安装Guard有两种方式:一种是直接下载Zend Guard安装包,解压并按照安装向导来安装;另一种方式是在安装Zend Studio(Zend 的一个IDE)的过程中从网络直接安装。

5.如何购买Zend Guard?

中国的用户购买Zend Guard,可以联系Zend中国技术支持中心:

MSN:zendchenhong@hotmail.com

6.Zend id是什么?如何生成Zend id?

Zend id用于绑定您使用Zend Guard的机器,生成一个Zend id后,如果您购买了Zend Guard,Zend会根据您的Zend id生成一个唯一对应您的许可文件。
如何生成Zend id请查看:

7.如何注册Zend Guard?

打开ZendGuard,点菜单中的help,选择Register,选择Serch a license file on my disk,找到你保存在本机的zend_guard.zl的路径,点击注册即注册成功。

8.Zend Guard中的Basic Encoding和Full Obfuscation指的是什么?

Zend Guard采用了三层防护机制:加密,混淆和许可文件管理,加密的级别依次递增,Encoding指的是基本的文件加密,而Obfuscation指的是将文件中的变量、函数、类等名称进行模糊处理,您可以根据自己的需要决定选用哪个级别的加密。

9.运行的加密文件出现以下类似错误提示:“Fatal error: Incompatible file format......”是什么原因?

这是因为Zend Optimizer的版本不兼容的问题,建议安装最新的Zend Optimizer,版本之间的对应关系可以查看FAQ问题3。

10.Zend Guard中的Work only with encoded files选项是什么含义?

Work only with encoded files是一种最高安全形式的加密,这是对您项目中所有的文件作为一个整体进行加密,以后当其中的某个文件单独提取出来运行或与其它项目的加密文件同时运行,这样是无法运行的。除非您为安全性考虑,我们还是不推荐加密时选择这个选项。
