在百度找的幾個asp sha1（vbs寫的）加密結果和asp.net的sha1加密結果不一樣，asp.net sha1加密完后是40位，網上找的asp sha1加密是64位，還以為asp.net做了截取（如網上的asp的md5機密和asp.net位數不一樣，是做了截取的問題），但是asp的64位加密結果并沒有包含asp.net的40位結果，看來找到的版本和asp.net的加密算法不一樣。

最后還是靠翻墻用google找到了一個js版本的sha1加密代碼結合asp使用后結果和asp.net的sha1加密一模一樣。。看來技術類的文字用度娘還是搞不過谷歌啊。。隨便fuck下中國的防火墻。。谷歌也給封了。

asp sha1加密源代碼如下，和asp.net的sha1加密結果一致:

代碼如下:
