3DES(DESede、TripleDES、DESEDE)加解密JAVA

对称加密(DES、3DES)、非对称加密(RSA、SHA1withRSA)

3DES、DESede、Triple-DES、DES-EDE名称相互都是别名

一、java加解密代码

默认模式为&＃xff1a;DESede/ECB/PKCS5Padding

package com.pd.shop.utils;import org.apache.tomcat.util.codec.binary.Base64;
import javax.crypto.*;
import javax.crypto.spec.DESedeKeySpec;
import java.security.Key;
import java.security.NoSuchAlgorithmException;public class DESedeUtils {/*** 默认 DESede/ECB/PKCS5Padding*/private static final String Algorithm &＃61; "DESede/ECB/PKCS5Padding";private static final String DESede &＃61; "DESede";private final static String Encoding &＃61; "utf-8";/*** DESede 加密** &＃64;param src 加密数据* &＃64;param key 密钥* &＃64;return*/public static String Encrypt(String src, String key) {String ss &＃61; "";try {byte[] b &＃61; Base64.decodeBase64(key);DESedeKeySpec spec &＃61; new DESedeKeySpec(b);SecretKeyFactory keyFactory &＃61; SecretKeyFactory.getInstance(DESede);Key secretKey &＃61; keyFactory.generateSecret(spec);Cipher c1 &＃61; Cipher.getInstance(Algorithm);c1.init(1, secretKey);b &＃61; c1.doFinal(src.getBytes());ss &＃61; Base64.encodeBase64String(b);} catch (NoSuchAlgorithmException e) {e.printStackTrace();} catch (NoSuchPaddingException e) {e.printStackTrace();} catch (Exception e) {e.printStackTrace();}return ss;}/*** DESede 解密** &＃64;param src 解密数据* &＃64;param key 密钥* &＃64;return*/public static String Decrypt(String src, String key) {try {byte[] s &＃61; Base64.decodeBase64(src);byte[] b &＃61; Base64.decodeBase64(key);DESedeKeySpec spec &＃61; new DESedeKeySpec(b);SecretKeyFactory keyFactory &＃61; SecretKeyFactory.getInstance(DESede);Key secretKey &＃61; keyFactory.generateSecret(spec);Cipher cipher &＃61; Cipher.getInstance(Algorithm);cipher.init(2, secretKey);byte[] decryptData &＃61; cipher.doFinal(s);return new String(decryptData, Encoding);} catch (Exception e) {e.printStackTrace();return null;}}
}


二·、加解密调用方法

String str &＃61; "001张三*";
String key &＃61; "5d48b92bfcccc1db9d3d965b32ead033";//加密调用方法
String encryptStr &＃61; DESedeUtils.Encrypt(str,key);
//结果 encryptStr &＃61; "eAgalz8MjYceOOI5V77fgA&＃61;&＃61;"//解密调用方法
String decryptStr &＃61; DESedeUtils.Decrypt(encryptStr,key);
//结果 decryptStr &＃61; "001张三*"
