流程

1. 读取硬件信息（此例中读取cpu和磁盘信息）
2. 加密
3. 解密

注意：1.磁盘信息包括插入的移动硬盘或U盘，如果将此信息也绑定，那么插入外部存储设备比如U盘的时候会误导加密程序。2.加密和解密采用通用的加密算法，需要添加用户自己的字段参与运算以增加加密可靠性，此例程中采用helloword字段参与加密运算，当然解密必须要采用与加密完全相同的字段。

1.读取硬件信息

所需命名空间：using System.Management;
代码段：

        private string GetSystemInfo() { ManagementClass mangnmt = new ManagementClass("Win32_LogicalDisk"); ManagementObjectCollection mcol = mangnmt.GetInstances(); string dskInfo = ""; foreach (ManagementObject strt in mcol) { dskInfo += Convert.ToString(strt["VolumeSerialNumber"]); } string cpuInfo = string.Empty; ManagementClass mc = new ManagementClass("win32_processor"); ManagementObjectCollection moc = mc.GetInstances(); foreach (ManagementObject mo in moc) { cpuInfo = mo.Properties["processorID"].Value.ToString(); break; } return cpuInfo + dskInfo; } 

2.加密

命名空间：using System.Security.Cryptography;
代码示例：

        private string Encrypt(string clearText) { string EncryptionKey = "helloword"; byte[] clearBytes = Encoding.Unicode.GetBytes(clearText); using (Aes encryptor = Aes.Create()) { Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 }); encryptor.Key = pdb.GetBytes(32); encryptor.IV = pdb.GetBytes(16); using (MemoryStream ms = new MemoryStream()) { using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateEncryptor(), CryptoStreamMode.Write)) { cs.Write(clearBytes, 0, clearBytes.Length); cs.Close(); } clearText = Convert.ToBase64String(ms.ToArray()); } } return clearText; } 

3. 解密

命名空间：using System.Security.Cryptography;
示例代码：

        private string Decrypt(string cipherText) { string EncryptionKey = "helloword"; cipherText = cipherText.Replace(" ", "+"); try { Convert.FromBase64String(cipherText); } catch(Exception e) { MessageBox.Show("The license code is not available!!!"); return ""; } byte[] cipherBytes = Convert.FromBase64String(cipherText); using (Aes encryptor = Aes.Create()) { Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 }); encryptor.Key = pdb.GetBytes(32); encryptor.IV = pdb.GetBytes(16); using (MemoryStream ms = new MemoryStream()) { using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateDecryptor(), CryptoStreamMode.Write)) { cs.Write(cipherBytes, 0, cipherBytes.Length); cs.Close(); } cipherText = Encoding.Unicode.GetString(ms.ToArray()); } } return cipherText; } 

此程序的加密程序是单独的应用，有界面，输入硬件字符信息后会产生加密后的数据。而且代码量很小，已上传至csdn，需要的可以下载参考
