The encryption results of several asp sha1 (written by vbs) I found on Baidu are different from those of asp.net's sha1 encryption. After the encryption of asp.net sha1 is 40 bits, the encryption of asp sha1 found on the Internet is 64 bits. I thought that asp.net has intercepted (for example, the number of md5 secrets of asp on the Internet is different from asp.net, which is a problem of intercepting), but the 64-bit encryption results of asp does not contain the 40-bit results of asp.net. It seems that the version found is different from the encryption algorithm of asp.net.
Finally, I used Google to search the wall and found a JS version of Sha1 encryption code and combined with Asp to use the result is exactly the same as the Sha1 encryption of Asp.net. . It seems that the technical text is still not good at Google. . Just fuck the firewall in China. . Google also blocked it.
The source code of asp sha1 encryption is as follows, which is consistent with the sha1 encryption result of asp.net:
The code copy is as follows:
