TripleDES CBC PKCS7PADDING 加密方式

此次使用的是CBC工作模式 - PKCS7PADDING填充格式

JAVA原始解密只有PKCS5PADDDING 需要引入第三方包

一下是GRADLE项目中的例子

首先引入第三包刷新一下GRADLE依赖

implementation('org.bouncycastle:bcprov-ext-jdk15on:1.64')

import java.security.Key;
import java.security.MessageDigest;
import java.util.Map;

import javax.crypto.Cipher;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.DESedeKeySpec;
import javax.crypto.spec.IvParameterSpec;

import org.apache.commons.codec.binary.Hex;
import org.springframework.util.Base64Utils;

 //原始文本
  String plainText = "山本你说句话，加密到底行不行";
  //密钥
  String secretKey = "ehahahTomCat#7=*";
  //向量
  String iv = "TomTaw#7";
  //字符集
  String encoding = "UTF-8";
  
  //注册一下上面引入的第三方解密方式 下面就可以无缝使用了
  Security.addProvider(new BouncyCastleProvider());

  try{
      Key deskey = null;
      //16位密钥转24位密钥
      byte[] keyBytes = secretKey.getBytes();
      if (keyBytes.length == 16) {
          byte[] tmpKey = new byte[24];
          System.arraycopy(keyBytes, 0, tmpKey, 0, 16);
          System.arraycopy(keyBytes, 0, tmpKey, 16, 8);
          keyBytes = tmpKey;
      }

      DESedeKeySpec spec = new DESedeKeySpec(keyBytes);
      SecretKeyFactory keyfactory = SecretKeyFactory.getInstance("desede");
      deskey = keyfactory.generateSecret(spec);

      Cipher cipher = Cipher.getInstance("desede/CBC/PKCS7Padding");
      IvParameterSpec ips = new IvParameterSpec(iv.getBytes());
      cipher.init(Cipher.ENCRYPT_MODE, deskey, ips);
      byte[] encryptData = cipher.doFinal(plainText.getBytes(encoding));
　　　　
      byte[] bb =  Base64Utils.encode(encryptData);

      String result = new String(bb,"UTF-8");

      System.out.println(result);

      return result;
  }catch(Exception e){
      e.printStackTrace();
  }
