ASP. NET MD5 Cryptographic functions (C #)

Using the following method, you can enter data directly, back to the MD5 encrypted code

<summary> ///UseMd5Encryption </summary> <param name= "Sourcein" >The data entered</param> <returns></returns> PublicStaticStringMD5 (StringSourcein) {MD5CryptoServiceProvider MD5CSP=NewMD5CryptoServiceProvider ();   byte[] Md5source = System.Text.Encoding.UTF8.GetBytes (Sourcein);    byte[] md5out = Md5csp.computehash (Md5source);    return convert.tobase64string (md5out); }

The above is only applicable to. Net md5 encryption, but now many companies are in asp asp.net stage, in order not to change the original teaching large user database, we need to find a kind of asp md5 after the same result of encryption, the following code is what I used to give you reference: Yellow part code
