ARIA 암호화모듈 이용한 구간 암호화

ARIA는 국내서 개발한 대칭키 암호화 기법이다.

- 암호화

import egovframework.rte.fdl.cryptography.EgovCryptoService;
import egovframework.rte.fdl.cryptography.EgovPasswordEncoder;
 
@Resource(name = "ARIACryptoService")
private EgovCryptoService egovCryptoService;
 
@Resource(name = "passwordEncoder")
private EgovPasswordEncoder passwordEncoder;
 
String pw = "aria1234"; //아리아 비밀번호 설정
String content = "test" //암호화할 내용
 
byte [] byteContent = content.getBytes("UTF-8"); //암호화시키려면 String -> Byte 로
byte [] encrypt = egovCryptoService.encrypt(byteContent,pw); //암호화
 
BASE64 base64 = new BASE64();
 
String encrypted = base64.encode(encrypt); //base64로 스트링 형변환
 
model.addAttribute("encrypted",encrypted);
 

 

- 복호화

import egovframework.rte.fdl.cryptography.EgovCryptoService;
import egovframework.rte.fdl.cryptography.EgovPasswordEncoder;
 
@Resource(name = "ARIACryptoService")
private EgovCryptoService egovCryptoService;
 
@Resource(name = "passwordEncoder")
private EgovPasswordEncoder passwordEncoder;
 
String pw = "aria1234"; //아리아 비밀번호 설정
 
BASE64 base64 = new BASE64();
String param = request.getParameter("encrypted");
 
byte [] decrypt = base64.decode(param); //String -> Byte 로 디코드
byte [] decrypted = egovCryptoService.decrypt(decrypt,pw); //복호화
 
String result = new String(decrypted,"UTF-8"); //최종 결과
