CommonUtils 생성

import org.springframework.stereotype.Component;
 
import egovframework.rte.fdl.cryptography.EgovPasswordEncoder;
import egovframework.rte.fdl.cryptography.impl.EgovARIACryptoServiceImpl;

import 선언

@Component("commUtils")
public class CommonUtils {

유틸 클래스 생성 후 @component 선언

    //복호화
    public byte[] decrypted(String value, String key){
        
        EgovPasswordEncoder egovPasswordEncoder = new EgovPasswordEncoder();
        EgovARIACryptoServiceImpl egovARIACryptoServiceImpl = new EgovARIACryptoServiceImpl();
        
        String hasedPassword = passwordEncoder.encryptPassword(key);
        egovPasswordEncoder.setHashedPassword(hasedPassword);
        egovPasswordEncoder.setAlgorithm("SHA-256");
        egovARIACryptoServiceImpl.setPasswordEncoder(egovPasswordEncoder);
        egovARIACryptoServiceImpl.setBlockSize(1025);
        
        byte[] decrypted = egovARIACryptoServiceImpl.decrypt(Base64.decodeBase64(value.getBytes()), key);
        return decrypted;
    }
    
    //암호화
    public byte[] encrypted(String value, String key){
        EgovPasswordEncoder egovPasswordEncoder = new EgovPasswordEncoder();
        EgovARIACryptoServiceImpl egovARIACryptoServiceImpl = new EgovARIACryptoServiceImpl();
        
        String hasedPassword = passwordEncoder.encryptPassword(key);
        egovPasswordEncoder.setHashedPassword(hasedPassword);

        egovARIACryptoServiceImpl.setPasswordEncoder(egovPasswordEncoder);
        egovARIACryptoServiceImpl.setBlockSize(1025);
        
        byte[] encrypted = egovARIACryptoServiceImpl.encrypt(value.getBytes(), key);
        return encrypted;
    }

Result

회원정보 중 email을 암호화

@Controller
public class UserController {
    
    @Resource(name="commUtils")
    private CommonUtils commUtils;

@controller를 선언 뒤 @resource 어노테이션을 통해 해당 @componet를 불러온다.

2번라인 encrypted은 암호화

byte[] decrypted= commUtils.decrypted(userVo.getUseremail(), Integer.toString(userVo.getUserno()));

1번라인 decrypted 은 복호화
