ASP implementation of SHA1 encryption and decryption code (and C # compatible) _ Application techniques

Baidu looking for several ASP SHA1 (VBS write) encryption results and ASP.net SHA1 encryption results, ASP.net SHA1 after the encryption is 40-bit, the Internet to find the ASP SHA1 encryption is 64-bit, Also thought ASP.net did intercept (such as the online ASP's MD5 secret and asp.net number is not the same, is to do the interception problem), but the ASP's 64-bit encryption results do not contain asp.net 40-bit results, it seems to find the version and ASP.net encryption algorithm is not the same.

Finally or by the wall with Google found a JS version of the SHA1 encryption code combined with the results of ASP and asp.net SHA1 encryption exactly. It seems that the technical type of words with the mother or do not make Google Ah. Casually fuck the Chinese firewall. Google has also been sealed.

ASP SHA1 encryption source code as follows, and ASP.net SHA1 encryption results are consistent:
