    asp实现的sha1加密解密代码(和C#兼容)

    在百度找的几个asp sha1(vbs写的)加密结果和asp.net的sha1加密结果不一样,asp.net sha1加密完后是40位,网上找的asp sha1加密是64位,还以为asp.net做了截取(如网上的asp的md5机密和asp.net位数不一样,是做了截取的问题),但是asp的64位加密结果并没有包含asp.net的40位结果,看来找到的版本和asp.net的加密算法不一样。
     
    最后还是靠翻墙用google找到了一个js版本的sha1加密代码结合asp使用后结果和asp.net的sha1加密一模一样。。看来技术类的文字用度娘还是搞不过谷歌啊。。随便fuck下中国的防火墙。。谷歌也给封了。
     
    asp sha1加密源代码如下,和asp.net的sha1加密结果一致:
