回答1:

php 源文件加密工具PHP Screw .

目前最新版本是1.3
网址
http://sourceforge.net/projects/php-screw/
我的安装环境
系统:Slackware 10
软件:Apache 1.3.31
PHP 4.3.7
以上环境全部是slackware 10默认安装后自带的。具体的Apache+php+mysql安装方法参照如下
支持php的Apache环境安装
获得软件
下载php_screw-1.3 (http://prdownloads.sourceforge.net/php-screw/php_screw-1.3.tgz?download)

安装
1.将获得的php_screw-1.3.tgz文件放到/usr/local目录下,然后用tar解压缩
tar zxvf php_screw-1.3.tgz

2.进入/usr/local/php_screw-1.3目录开始安装
cd /usr/local/php_screw-1.3
phpize
./confiugre

3.设置自己用来加密的密码
vi my_screw.h

-- Please change the encryption SEED key (pm9screw_mycryptkey) into the
values according to what you like.
The encryption will be harder to break, if you add more values to the
encryption SEED array. However, the size of the SEED is unrelated to
the time of the decrypt processing.

* If you can read and understand the source code, to modify an original
encryption logic will be possible. But in general, this should not
be necessary.

OPTIONAL: Encrypted scripts get a stamp added to the beginning of the
file. If you like, you may change this stamp defined by
PM9SCREW and PM9SCREW_LEN in php_screw.h. PM9SCREW_LEN must
be less than or equal to the size of PM9SCREW.

4.编译
make

5.拷贝modules目录下的php_screw.so文件到/usr/lib/php/extension目录下
cp modules/php_screw.so /usr/lib/php/extension/

6.编辑php.ini文件
在php.ini文件里,加入如下语句
extension=php_screw.so

7.重新启动Apache
/etc/rc.d/rc.httpd restart

8.编译加密工具
cd tools
make

9.将tools目录下加密用的工具screw拷贝到适当目录
cp screw /usr/bin/

经过以上的10步,就已经把php_screw-1.3全部安装完成了。并且现在的php也已经支持解释加密过的php文件了
使用
1.现写一个要加密的php文件。
我写了如下的一个用来测试php速度的compute.php文件

$a=0;
$t=time();
for($i=0;$i<5000000;$i++)
{$a=$a*$i;}
$t1=time();
echo "

";
echo "It used:";
echo $t1-$t;
echo "seconds";
?>
将上面的compute.php文件放到/var/www/htdocs目录下。通过浏览器访问,将显示出php在大量计算时的速度(只能粗略估计一下)
2.将我们写的php文件加密
cd /var/www/htdocs/
screw compute.php

我们加密后,现在目录下的compute.php文件就是我们已经加密的了。而源文件被改名为compute.php.screw存放了。
我们现在再测试一下compute.php,看看能否正常使用?速度如何?
我比较了一下,加密前后的速度大概一样,基本没有太多的损失。

回答2:

有解密的时间,不如自己写一个,因为解密出来的东西,肯定不完整,会有大量的错误的!

回答3:

ZendSafeGuard-Evaluation-3.6.0-Windows-i386.exe
与ZendOptimizer合用,都是PHP官方软件,一个加密一个解密

回答4:

ZEnd加密。
