使用truelicense进行Java程序license控制

经过扩张可以验证license 开始结束日期，验证绑定给定mac地址。

Truelicense 是一个开源的java license 验证项目。

使用truelicense实现用于JAVA工程license机制（包括license生成和验证）请参考[http://www.it165.net/pro/html/201404/11540.html][http_www.it165.net_pro_html_201404_11540.html]

其中包括license授权机制的原理和制作license的具体步骤

本文主要是在此文基础上增加了mac 地址验证：

在createparam.properties

中增加 ip地址和 mac 地址的配置

##########common parameters###########
    #alias
    PRIVATEALIAS=privateKeys
    #key(important!)
    KEYPWD=iptv1234
    #STOREPWD
    STOREPWD=iptv1234
    #SUBJECT
    SUBJECT=bigdata
    #licPath
    licPath=C:/9exce/license/license.lic
    #priPath
    priPath=C:/9exce/license/PrivateKeys.keystore
    ##########license content###########
    #issuedTime
    issuedTime=2015-03-09
    #notBeforeTime
    notBefore=2015-03-09
    #notAfterTime
    notAfter=2016-03-20
    #ip address
    ipAddress=150.236.220.200
    #mac address
    macAddress=80-00-0B-56-3B-32
    #consumerType
    consumerType=user
    #ConsumerAmount
    consumerAmount=1
    #info
    info=this is a license

因为增加了mac地址，需要改变LicenseManager中的validate函数增加create\_validate 用于create时的verify, 因为创建证书的时候 不能验证mac地址。

protected synchronized void create_validate(LicenseContent paramLicenseContent)
    			throws LicenseContentException {
    		LicenseParam localLicenseParam = getLicenseParam();
    		if (!localLicenseParam.getSubject().equals(
    				paramLicenseContent.getSubject())) {
    			throw new LicenseContentException(EXC_INVALID_SUBJECT);
    		}
    		if (paramLicenseContent.getHolder() == null) {
    			throw new LicenseContentException(EXC_HOLDER_IS_NULL);
    		}
    		if (paramLicenseContent.getIssuer() == null) {
    			throw new LicenseContentException(EXC_ISSUER_IS_NULL);
    		}
    		if (paramLicenseContent.getIssued() == null) {
    			throw new LicenseContentException(EXC_ISSUED_IS_NULL);
    		}
    		Date localDate1 = new Date();
    		Date localDate2 = paramLicenseContent.getNotBefore();
    		if ((localDate2 != null) && (localDate1.before(localDate2))) {
    			throw new LicenseContentException(EXC_LICENSE_IS_NOT_YET_VALID);
    		}
    		Date localDate3 = paramLicenseContent.getNotAfter();
    		if ((localDate3 != null) && (localDate1.after(localDate3))) {
    			throw new LicenseContentException(EXC_LICENSE_HAS_EXPIRED);
    		}	
    		
    		String str = paramLicenseContent.getConsumerType();
    		if (str == null) {
    			throw new LicenseContentException(EXC_CONSUMER_TYPE_IS_NULL);
    		}
    		Preferences localPreferences = localLicenseParam.getPreferences();
    		if ((localPreferences != null) && (localPreferences.isUserNode())) {
    			if (!USER.equalsIgnoreCase(str)) {
    				throw new LicenseContentException(EXC_CONSUMER_TYPE_IS_NOT_USER);
    			}
    			if (paramLicenseContent.getConsumerAmount() != 1) {
    				throw new LicenseContentException(
    						EXC_CONSUMER_AMOUNT_IS_NOT_ONE);
    			}
    		} else if (paramLicenseContent.getConsumerAmount() <= 0) {
    			throw new LicenseContentException(
    					EXC_CONSUMER_AMOUNT_IS_NOT_POSITIVE);
    		}
    	}

更新validate增加验证客户server的mac地址。

protected synchronized void validate(LicenseContent paramLicenseContent)
    			throws LicenseContentException {
    		LicenseParam localLicenseParam = getLicenseParam();
    		if (!localLicenseParam.getSubject().equals(
    				paramLicenseContent.getSubject())) {
    			throw new LicenseContentException(EXC_INVALID_SUBJECT);
    		}
    		if (paramLicenseContent.getHolder() == null) {
    			throw new LicenseContentException(EXC_HOLDER_IS_NULL);
    		}
    		if (paramLicenseContent.getIssuer() == null) {
    			throw new LicenseContentException(EXC_ISSUER_IS_NULL);
    		}
    		if (paramLicenseContent.getIssued() == null) {
    			throw new LicenseContentException(EXC_ISSUED_IS_NULL);
    		}
    		Date localDate1 = new Date();
    		Date localDate2 = paramLicenseContent.getNotBefore();
    		if ((localDate2 != null) && (localDate1.before(localDate2))) {
    			throw new LicenseContentException(EXC_LICENSE_IS_NOT_YET_VALID);
    		}
    		Date localDate3 = paramLicenseContent.getNotAfter();
    		if ((localDate3 != null) && (localDate1.after(localDate3))) {
    			throw new LicenseContentException(EXC_LICENSE_HAS_EXPIRED);
    		}
    		
    		LicenseCheckModel licenseCheckModel = (LicenseCheckModel)paramLicenseContent.getExtra();
    		String macAddress = licenseCheckModel.getIpMacAddress();
    		
    		try {
    			if (!ListNets.validateMacAddress(macAddress)) {
    				throw new LicenseContentException(EXC_LICENSE_HAS_EXPIRED);
    			}
    		} catch (SocketException e) {
    			// TODO Auto-generated catch block
    			throw new LicenseContentException(EXC_LICENSE_HAS_EXPIRED);
    		}
    		
    		
    		String str = paramLicenseContent.getConsumerType();
    		if (str == null) {
    			throw new LicenseContentException(EXC_CONSUMER_TYPE_IS_NULL);
    		}
    		Preferences localPreferences = localLicenseParam.getPreferences();
    		if ((localPreferences != null) && (localPreferences.isUserNode())) {
    			if (!USER.equalsIgnoreCase(str)) {
    				throw new LicenseContentException(EXC_CONSUMER_TYPE_IS_NOT_USER);
    			}
    			if (paramLicenseContent.getConsumerAmount() != 1) {
    				throw new LicenseContentException(
    						EXC_CONSUMER_AMOUNT_IS_NOT_ONE);
    			}
    		} else if (paramLicenseContent.getConsumerAmount() <= 0) {
    			throw new LicenseContentException(
    					EXC_CONSUMER_AMOUNT_IS_NOT_POSITIVE);
    		}
    	}

创建类ListNets 用于读取客户server的IP地址和mac地址进行验证，笔者使用了验证mac地址的函数，毕竟客户有可能更改机器的ip地址的

package zlicense.util;
     
     
    import java.net.*;
    import java.util.*;
     
    import static java.lang.System.out;
     
    public class ListNets {
     
    	public static void main(String args[]) throws SocketException {	
    		String ip = "150.236.220.200";
    		String mac = "80-00-0B-56-3B-32";
    		boolean flag = validatoIpAndMacAddress(ip, mac);
    		boolean macflag = validateMacAddress( mac);
    		out.printf("validatoMacAddress flag=%s\n", macflag);
    		out.printf("validatoIpAndMacAddress flag=%s\n", flag);		
    	}
     
    	static void displayInterfaceInformation(NetworkInterface netint)
    			throws SocketException {
    		out.printf("Display name: %s\n", netint.getDisplayName());
    		out.printf("Name: %s\n", netint.getName());
    		byte[] mac = netint.getHardwareAddress();
    		if (mac != null) {
    			StringBuilder sb = new StringBuilder();
    			for (int i = 0; i < mac.length; i++) {
    				sb.append(String.format("%02X%s", mac[i],
    						(i < mac.length - 1) ? "-" : ""));
    			}
    			System.out.println("mac=" + sb.toString());
    		}
     
    		Enumeration<InetAddress> inetAddresses = netint.getInetAddresses();
    		for (InetAddress inetAddress : Collections.list(inetAddresses)) {
    			out.printf("InetAddress: %s\n", inetAddress);
    			System.out
    					.println("InetAddress ip=" + inetAddress.getHostAddress());
    		}
    		out.printf("\n");
    	}
     
    	public static boolean validateMacAddress(String macAddress)
    			throws SocketException {
    		boolean returnFlag = false;
    		Enumeration<NetworkInterface> nets = NetworkInterface
    				.getNetworkInterfaces();
    		for (NetworkInterface netint : Collections.list(nets)) {
    			byte[] mac = netint.getHardwareAddress();
    			StringBuilder sb = new StringBuilder();
    			if (mac != null) {
    				for (int i = 0; i < mac.length; i++) {
    					sb.append(String.format("%02X%s", mac[i],
    							(i < mac.length - 1) ? "-" : ""));
    				}
    				System.out.println("mac=" + sb.toString());
    			}
    			if (sb.toString().equals(macAddress)) {
    				returnFlag = true;
    			}
    		}
    		return returnFlag;
     
    	}
     
    	public static boolean validatoIpAndMacAddress(String ipAddress,
    			String macAddress) throws SocketException {
    		boolean returnFlag = false;
    		Enumeration<NetworkInterface> nets = NetworkInterface
    				.getNetworkInterfaces();
    		for (NetworkInterface netint : Collections.list(nets)) {
    			byte[] mac = netint.getHardwareAddress();
    			StringBuilder sb = new StringBuilder();
    			if (mac != null) {
    				for (int i = 0; i < mac.length; i++) {
    					sb.append(String.format("%02X%s", mac[i],
    							(i < mac.length - 1) ? "-" : ""));
    				}
    				System.out.println("mac=" + sb.toString());
    			}
    			if (sb.toString().equals(macAddress)) {
    				Enumeration<InetAddress> inetAddresses = netint
    						.getInetAddresses();
    				String ip = "";
    				for (InetAddress inetAddress : Collections.list(inetAddresses)) {
    					ip = inetAddress.getHostAddress();
    					System.out.println("InetAddress ip="
    							+ inetAddress.getHostAddress());
    					if (ipAddress.toString().equals(ip)) {
    						returnFlag = true;
    					}
    				}
    			}
    		}
    		return returnFlag;
     
    	}
    }

创建LicenseCheckModel 是一个model类就是存储 ip和mac地址

package zlicense.util;
     
    public class LicenseCheckModel {
    	
    	private String ipAddress;    
    	private String ipMacAddress;
    	private String CPUSerial;
    	private String motherboardSN;
    	private String hardDiskSN;
    	
    	
    	public String getIpAddress() {
    		return ipAddress;
    	}
    	public void setIpAddress(String ipAddress) {
    		this.ipAddress = ipAddress;
    	}
    	public String getIpMacAddress() {
    		return ipMacAddress;
    	}
    	public void setIpMacAddress(String ipMacAddress) {
    		this.ipMacAddress = ipMacAddress;
    	}
    	public String getCPUSerial() {
    		return CPUSerial;
    	}
    	public void setCPUSerial(String cPUSerial) {
    		CPUSerial = cPUSerial;
    	}
    	public String getMotherboardSN() {
    		return motherboardSN;
    	}
    	public void setMotherboardSN(String motherboardSN) {
    		this.motherboardSN = motherboardSN;
    	}
    	public String getHardDiskSN() {
    		return hardDiskSN;
    	}
    	public void setHardDiskSN(String hardDiskSN) {
    		this.hardDiskSN = hardDiskSN;
    	}
     
    }

更新CreateLicense 增加mac和ip 的配置读取并写入license证书，采用了content.setExtra(licenseCheckModel);

将需要验证的信息 写入licenseCheckModel 然后set到content中。

改变了 truelicense 中所有的文件读取方式，采用绝对路径读取。

Properties prop= new Properties();
                       //InputStream in= getClass().getResourceAsStream(propertiesPath);
                      
                       try {
                                InputStreamin = new FileInputStream(propertiesPath);
                                prop.load(in);
                       } catch(IOException e) {
                                // TODOAuto-generated catch block
                                e.printStackTrace();
                       }

所有的配置文件和我生成的 key stroe 在java-license-jar/src/main/resources文件夹下
