基于C#的软件加密、授权与注册
|
本文介绍了基于 本机特征信息（如CPU、主板、BIOS和MAC等） 的软件加密、授权与注册方法，并分享了 示例程序完整源代码。 目录 1 加密、授权与注册2 本机特征信息3 加密与解密算法4 软件授权检测5 示例程序5.1 界面设计5.2 模块代码5.3 完整代码下载 1 加密、授权与注册软件的加密、授权与注册流程如下：
本机特征信息主要包括：①CPU信息、②主板序列号、③BIOS信息、④MAC地址，基于C#获取代码如下： using System; using System.Management; using System.Net.NetworkInformation; using Microsoft.Win32; namespace RWRegister { public class Computer { public static string ComputerInfo() { string info = string.Empty; string cpu = GetCPUInfo(); string baseBoard = GetBaseBoardInfo(); string bios = GetBIOSInfo(); string mac = GetMACInfo(); info = string.Concat(cpu, baseBoard, bios, mac); return info; } private static string GetCPUInfo() { string info = string.Empty; info = GetHardWareInfo("Win32_Processor", "ProcessorId"); return info; } private static string GetBaseBoardInfo() { string info = string.Empty; info = GetHardWareInfo("Win32_BaseBoard", "SerialNumber"); return info; } private static string GetBIOSInfo() { string info = string.Empty; info = GetHardWareInfo("Win32_BIOS", "SerialNumber"); return info; } private static string GetMACInfo() { string info = string.Empty; info = GetMacAddressByNetwork(); return info; } private static string GetHardWareInfo(string typePath, string Key) { try { ManagementClass mageClass = new ManagementClass(typePath); ManagementObjectCollection mageObjectColl = mageClass.GetInstances(); PropertyDataCollection Properties = mageClass.Properties; foreach (PropertyData property in Properties) { if (property.Name == Key) { foreach (ManagementObject mageObject in mageObjectColl) { return mageObject.Properties[property.Name].Value.ToString(); } } } } catch (Exception ex) { throw new Exception(ex.Message); } return string.Empty; } private static string GetMacAddressByNetwork() { string Key = "SYSTEM\\CurrentControlSet\\Control\\Network\\{4D36E972-E325-11CE-BFC1-08002BE10318}\\"; string macAddress = string.Empty; try { NetworkInterface[] Nics = NetworkInterface.GetAllNetworkInterfaces(); foreach (NetworkInterface adapter in Nics) { if (adapter.NetworkInterfaceType == NetworkInterfaceType.Ethernet && adapter.GetPhysicalAddress().ToString().Length != 0) { string fRegistryKey = Key + adapter.Id + "\\Connection"; RegistryKey rKey = Registry.LocalMachine.OpenSubKey(fRegistryKey, false); if (rKey != null) { string fPnpInstanceID = rKey.GetValue("PnpInstanceID", "").ToString(); int fMediaSubType = Convert.ToInt32(rKey.GetValue("MediaSubType", 0)); if (fPnpInstanceID.Length > 3 && fPnpInstanceID.Substring(0, 3) == "PCI") { macAddress = adapter.GetPhysicalAddress().ToString(); for (int i = 1; i |
