详解.NET下的加密解密算法（1） 哈希加密2013-08-18 csdn ghostbear.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

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

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

SHA256

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

SHA384

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

SHA512

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