. Net MD5 application practices

Encrypted strings are one of the key factors to improve system security. Improved encryption calling in vs2005, such as the MD5 method.

I will not talk about the MD5 algorithm. After all, it is not my research. We only need to know about it.

MD5 Algorithm:

Private string getmd5 (string Str)
...{
Byte [] bysrc = system. Text. encoding. Default. getbytes (STR );

Bysrc = new system. Security. cryptography. md5cryptoserviceprovider (). computehash (bysrc );

String md5str = "";

For (INT I = 0; I <bysrc. length; I ++)
...{
Md5str + = bysrc [I]. tostring ("X"). padleft (2, '0 ');
}
Return md5str;
}

 

For example, input:

Test

098f6bcd4621d373cade4e832627b4f6

The encrypted string length is 32 characters.

You can use other tests.
