Detailed. NET encryption and decryption algorithm (1) hash encryption

. NET has a wealth of encryption and decryption API library for our use, this blog summary. NET hash hash algorithm, and made into a simple demo, hope to be helpful to everyone.

MD5

Using System;  
Using System.Collections.Generic;  
Using System.Text;  
      
Using System.Security.Cryptography;  
      
Namespace Encryptanddecrypt  
{public  
    class MD5  
    {public  
        byte[] Hash (byte[] data)  
        {  
            System.Security.Cryptography.MD5 MD5 = System.Security.Cryptography.MD5.Create ();  
      
            return Md5.computehash (data);}}  

SHA1

    class SHA1  
    {public  
        byte[] Hash (byte[] data)

            System.Security.Cryptography.SHA1 SHA1 = System.Security.Cryptography.SHA1.Create ();  
            return Sha1.computehash (data);}}  

SHA256

            return Sha256.computehash (data);}}  

SHA384
