对称加密(DES、3DES)、非对称加密(RSA、SHA1withRSA)
参考:

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：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 = "DESede/ECB/PKCS5Padding";private static final String DESede = "DESede";private final static String Encoding = "utf-8";/*** DESede 加密** @param src 加密数据* @param key 密钥* @return*/public static String Encrypt(String src, String key) {String ss = "";try {byte[] b = Base64.decodeBase64(key);DESedeKeySpec spec = new DESedeKeySpec(b);SecretKeyFactory keyFactory = SecretKeyFactory.getInstance(DESede);Key secretKey = keyFactory.generateSecret(spec);Cipher c1 = Cipher.getInstance(Algorithm);c1.init(1, secretKey);b = c1.doFinal(src.getBytes());ss = Base64.encodeBase64String(b);} catch (NoSuchAlgorithmException e) {e.printStackTrace();} catch (NoSuchPaddingException e) {e.printStackTrace();} catch (Exception e) {e.printStackTrace();}return ss;}/*** DESede 解密** @param src   解密数据* @param key   密钥* @return*/public static String Decrypt(String src, String key) {try {byte[] s = Base64.decodeBase64(src);byte[] b = Base64.decodeBase64(key);DESedeKeySpec spec = new DESedeKeySpec(b);SecretKeyFactory keyFactory = SecretKeyFactory.getInstance(DESede);Key secretKey = keyFactory.generateSecret(spec);Cipher cipher = Cipher.getInstance(Algorithm);cipher.init(2, secretKey);byte[] decryptData = 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 = "001张三*";
String key = "5d48b92bfcccc1db9d3d965b32ead033";//加密调用方法
String encryptStr = DESedeUtils.Encrypt(str,key);
//结果 encryptStr = "eAgalz8MjYceOOI5V77fgA=="//解密调用方法
String decryptStr = DESedeUtils.Decrypt(encryptStr,key);
//结果 decryptStr = "001张三*"
