把普通链接转为迅雷、旋风、快车链接（过程返过来就可以把迅雷、旋风、快车链接变成普通链接）
关于迅雷、快车、超级旋风下载地址加密算法都是通过base64算法加密,只不过在加密前后做了一些特别的标志。Base64编码是一种加密算法
1、迅雷专用链接编码
原地址为：/install/BaiduHi.exe
a 在原地址前面加"AA"，后面加"ZZ"(不包括引号)，地址变为：AA/install/BaiduHi.exeZZ
b 此地址base64编码为：
QUFodHRwOi8vaW0uYmFpZHUuY29tL2luc3RhbGwvQmFpZHVIaS5leGVaWg==
c 迅雷专链即在上地址前加thunder://，即：
Thunder://QUFodHRwOi8vaW0uYmFpZHUuY29tL2luc3RhbGwvQmFpZHVIaS5leGVaWg==
2、快车专用链接编码
a 在原地址前后都加上"[FLASHGET]"(不包括引号)，地址变为：[FLASHGET]/install/BaiduHi.exe[FLASHGET]
b 此地址base64编码为：
W0ZMQVNIR0VUXWh0dHA6Ly9pbS5iYWlkdS5jb20vaW5zdGFsbC9CYWlkdUhpLmV4ZVtGTEFTSEdFVF0=&yinbing1986
c 快车专链即在上地址前加flashget://，注意后面还要加上"&符号"，符号怎么得出不清楚，在最后后面加的是个人信息，可加可不加。
Flashget://W0ZMQVNIR0VUXWh0dHA6Ly9pbS5iYWlkdS5jb20vaW5zdGFsbC9CYWlkdUhpLmV4ZVtGTEFTSEdFVF0=&yinbing1986
注意：在把快车专用链接变成普通链接时，要取[FLASHGET]之间的信息。
3、旋风专用链接编码
a 旋风相对就简单多了，将原地址直接base64编码为
aHR0cDovL2ltLmJhaWR1LmNvbS9pbnN0YWxsL0JhaWR1SGkuZXhl
b 旋风专链即在上地址前加qqdl://，即
qqdl://aHR0cDovL2ltLmJhaWR1LmNvbS9pbnN0YWxsL0JhaWR1SGkuZXhl
4、 知道其原理后，要解密起来就有了方法，但是有没有最直接的方法呢？有
打开网址/code/urlconvert/
Base64编码与解码网址：/
代码如下：
