Nodejsで暗号化と復号化する

More than 5 years have passed since last update.

暗号化と復号化

node
var crypto = require('crypto');
var algorithm = 'aes-256-ctr';
var passphrase = "7IeZlmfz";

var encrypt = (text) => {
  var cipher = crypto.createCipher(algorithm,passphrase)
  var crypted = cipher.update(text,'utf8','base64')
  crypted += cipher.final('base64');
  return crypted;
}

var decrypt = (text) => {
  var decipher = crypto.createDecipher(algorithm,passphrase)
  var dec = decipher.update(text,'base64','utf8')
  dec += decipher.final('utf8');
  return dec;
}

確認

node
console.log(encrypt("こんにちは"));
console.log(decrypt(encrypt("こんにちは")));
