oracle中的encrypt_des加密对应Java的加密方式

将18693157906加密后的密文是 FAD42A3BB2A4B9A5B36847714A56FE65

二、java中对应的加密、解密方法

public class Utils {

#密钥	
private static String key = "test#5&124*!de";
	
 
   public static String ENCRYPT_DES(String inStr)  { 
	   DESKeySpec desKey;
	   SecreTKEy securekey;
	   Cipher cipher; 
	  try {
		
		desKey = new DESKeySpec(key.getBytes());
		securekey = SecretKeyFactory.getInstance("DES").generateSecret(desKey);
	    cipher = Cipher.getInstance("DES/CBC/NoPadding");
	    cipher.init(Cipher.ENCRYPT_MODE, securekey, new IvParameterSpec(new byte[8]));
        byte[] inBytes = new byte[((int) (inStr.length() / 8) + 1) * 8];
        for (int i = 0; i < inStr.length(); i++) {
        inBytes[i] = inStr.getBytes()[i];
        }
       byte[] enBytes = cipher.doFinal(inBytes);
       String hexStr = DatatypeConverter.printHexBinary(enBytes);
       return hexStr;
        
	} catch (Exception e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}

	return null;
	   
   }
	
   
   public static  String DECRYPT_DES(String encryptStr)  { 
	   DESKeySpec desKey;
	   SecretKey securekey;
	   Cipher cipher; 
	 try {
		 desKey = new DESKeySpec(key.getBytes());
         securekey = SecretKeyFactory.getInstance("DES").generateSecret(desKey);
	     cipher = Cipher.getInstance("DES/CBC/NoPadding");
	     cipher.init(Cipher.DECRYPT_MODE, securekey, new IvParameterSpec(new byte[8]));
		 byte[] decryptBytes = cipher.doFinal(Hex.decodeHex(encryptStr.toCharArray()));
		 return new String(decryptBytes).trim();
		
	} catch (Exception e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}

	return null;
	   
   }
   
   public static void main(String[] args) {
	   System.out.println("加密："+ENCRYPT_DES("18693157906"));
	   System.out.println("解密："+DECRYPT_DES("FAD42A3BB2A4B9A5B36847714A56FE65"));
}
	
 
}

三、运行代码得到结果

可以看到加密后的密文是FAD42A3BB2A4B9A5B36847714A56FE65

解密后的明文是18693157906

跟数据库加密一致
