[Node.js] 암호화/복호화

1. 암호화

const algorithm = 'aes-256-cbc';
const key = 'abcdefghijklmnopqrstuvwxyz123456';
const iv = '1234567890123456';
 
const cipher = crypto.createCipheriv(algorithm, key , iv );
let cryptoEmail = cipher.update(user?.email, 'utf8', 'base64');
// 아래 안 적으면 복호화 안됨
cryptoEmail += cipher.final('base64');

 

2. 복호화

const decipher = crypto.createDecipheriv(algorithm, key , iv);
let decodeEmail = decipher.update(cryptoEmail,'base64','utf8');
// 아래 안 적으면 복호화 안됨
decodeEmail += decipher.final('utf8');
