Java版适用于PHP版3DES加密解密

1、Java版适用于PHP版3DES加密解密import javax.crypto.Cipher;import javax.crypto.SecretKey;import javax.crypto.spec.SecretKeySpec;import org.apache.log4j.Logger;import sun.misc.BASE64Decoder;import sun.misc.BASE64Encoder; /* Java版3DES加密解密，适用于PHP版3DES加密解密(PHP语言开发的MCRYPT_3DES算法、MCRYPT_MODE_ECB模式、PKCS7填充方式)* author

2、G007N*/public class DesBase64Tool private static SecretKey secretKey = null;/key对象private static Cipher cipher = null; /私鈅加密对象Cipherprivate static String keyString = AKlMU89D3FchIkhKyMma6FiE;/密钥private static Logger log = Logger.getRootLogger();static try secretKey = new SecretKeySpec(keyString.getB

3、ytes(), DESede);/获得密钥/*获得一个私鈅加密类Cipher，DESede是算法，ECB是加密模式，PKCS5Padding是填充方式*/ cipher = Cipher.getInstance(DESede/ECB/PKCS5Padding); catch (Exception e) log.error(e.getMessage(), e);/* * 加密 * param message * return */ public static String desEncrypt(String message) String result = ; /DES加密字符串 String

4、newResult = ;/去掉换行符后的加密字符串 try cipher.init(Cipher.ENCRYPT_MODE, secretKey);/设置工作模式为加密模式，给出密钥 byte resultBytes = cipher.doFinal(message.getBytes(UTF-8);/正式执行加密操作 BASE64Encoder enc = new BASE64Encoder();result = enc.encode(resultBytes);/进行BASE64编码newResult = filter(result); /去掉加密串中的换行符 catch (Exceptio

5、n e) log.error(e.getMessage(), e);return newResult; /* * 解密 * param message * return * throws Exception */ public static String desDecrypt(String message) throws Exception String result = ; try BASE64Decoder dec = new BASE64Decoder(); byte messageBytes = dec.decodeBuffer(message); /进行BASE64编码 cipher

6、.init(Cipher.DECRYPT_MODE, secretKey); /设置工作模式为解密模式，给出密钥 byte resultBytes = cipher.doFinal(messageBytes);/正式执行解密操作 result = new String(resultBytes,UTF-8); catch (Exception e) e.printStackTrace();return result; /* * 去掉加密字符串换行符 * param str * return */public static String filter(String str) String outp

7、ut = ; StringBuffer sb = new StringBuffer(); for (int i = 0; i str.length(); i+) int asc = str.charAt(i); if (asc != 10 & asc != 13) sb.append(str.subSequence(i, i+1); output = new String(sb); return output; /* * 加密解密测试 * param args */public static void main(String args) try String strText = Hello world!;String deseResult = desEncrypt(strText);/加密System.out.println(加密结果：+deseResult);String de
