php mcrypt 初解

在某位大师的指导要求下，刚把今天代码做ending的我，来看一下mcrypt，安装就不说了，

extension=php_mcrypt.dll

加密算法

Mcrypt支持的算法有：

cast-128,gost,rijndael-128,twofish,arcfour,cast-256,loki97,rijndael-192,saferplus,wake,blowfish-compat,des,rijndael-256,serpent,xtea,blowfish,enigma,rc2,tripledes

加密模式

Mcrypt支持的加密模式有：

cbc,cfb,ctr,ecb,ncfb,nofb,ofb,stream

$cipher='xtea';
$key='Sir';
$data='I Love You !';
$mode='ecb';
$encStr=mcrypt_encrypt($cipher,$key,$data,$mode);//加密

print_r($encStr);

$cipher='xtea';
$key='';
$data='I Love You !';
$mode='ecb';
$encStr=mcrypt_encrypt($cipher,$key,$data,$mode);
print_r($encStr);

$key:将和data一起被加密，密钥

$cipher='xtea';
$key='';
$data='I Love You !';
$mode='ecb';
$encStr=mcrypt_encrypt($cipher,$key,$data,$mode);//编码
$decStr=mcrypt_decrypt($cipher, $key,$encStr , $mode);//解码
print_r($encStr);

print_r($decStr);

我刚开始看，看帮助手册吧，
