</HTML>迅雷(thunder)/快车(FlashGet)/旋风(qqdl)下载地址转换/还原工具
迅雷(thunder)/快车(FlashGet)/旋风(qqdl)的下载地址都是由普通的地址经过base64编码而来，但具体过程稍微有点不同：迅雷是在普通地址前后分别加了"AA"和"ZZ"之后进行base64编码，然后在最前方加入"thunder://"而成，最终如"thunder://QUFodHRwOi8vd3d3Lm16d3UuY29tL2RlZmF1bHQuYXNwWlo="；而快车则是在普通地址前后都加"[flashget]"之后进行base64编码，然后在最前方加入"flashget://"最后方加入"&id数字&数字"而成，最终如"Flashget://W0ZMQVNIR0VUXWh0dHA6Ly93d3cubXp3dS5jb20vZGVmYXVsdC5hc3BbRkxBU0hHRVRd& 566&1204532909"；旋风最为简单，直接将普通地址使用base64编码，并在最前方加入"qqdl://"而成，最终如"qqdl://aHR0cDovL3d3dy5tend1LmNvbS9kZWZhdWx0LmFzcA=="。知道了原理，要将普通地址base64编码进行转换或将转换后的地址还原为普通地址就不难了，下边是一个迅雷(thunder)/快车(FlashGet)/旋风(qqdl)下载地址转换/还原工具：
