.NET下的加密解密大全（1）: 哈希加密

.NET有丰富的加密解密API库供我们使用，本博文总结了.NET下的Hash散列算法，并制作成简单的DEMO，希望能对大家有所帮助。

MD5
[csharp]
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
[csharp]
using System; 
using System.Collections.Generic; 
using System.Text; 
 
using System.Security.Cryptography; 
 
namespace EncryptAndDecrypt 
{ 
    public class SHA1:IHash 
    { 
        public byte[] Hash(byte[] data) 
        { 
            System.Security.Cryptography.SHA1 sha1 = System.Security.Cryptography.SHA1.Create(); 
            return sha1.ComputeHash(data); 
        } 
    } 
}

SHA256
[csharp]
using System; 
using System.Collections.Generic; 
using System.Text; 
 
using System.Security.Cryptography; 
 
namespace EncryptAndDecrypt 
{ 
    public class SHA256:IHash 
    { 
 
 
        public byte[] Hash(byte[] data) 
        { 
            System.Security.Cryptography.SHA256 sha256=  System.Security.Cryptography.SHA256.Create(); 
            return sha256.ComputeHash(data); 
        } 
    } 
}

SHA384
[csharp]
using System; 
using System.Collections.Generic; 
using System.Text; 
 
using System.Security.Cryptography; 
namespace EncryptAndDecrypt 
{ 
    public class SHA384:IHash 
    { 
 
        public byte[] Hash(byte[] data) 
        { 
            System.Security.Cryptography.SHA384 sha384 = System.Security.Cryptography.SHA384.Create(); 
            return sha384.ComputeHash(data); 
        } 
    } 
}

SHA512
[csharp]
using System; 
using System.Collections.Generic; 
using System.Text; 
 
using System.Security.Cryptography; 
 
namespace EncryptAndDecrypt 
{ 
    public class SHA512:IHash 
    { 
 
        public byte[] Hash(byte[] data) 
        { 
            System.Security.Cryptography.SHA512 sha512 = System.Security.Cryptography.SHA512.Create(); 
            return sha512.ComputeHash(data); 
        } 
    } 
}
