crypto-js的用法 des加密和解密写好的方法。

var CryptoJS = require('crypto-js');
var config = require('../config/config');
var desUtil = {
    encryptByDESModeEBC: function encryptByDESModeEBC(message) {
        var keyHex = CryptoJS.enc.Utf8.parse(config.salt);
        var encrypted = CryptoJS.DES.encrypt(message, keyHex, {
            mode: CryptoJS.mode.ECB,
            padding: CryptoJS.pad.Pkcs7
        });
        return encrypted.ciphertext.toString(); //DES  ECB模式加密
    },
    decryptByDESModeEBC: function decryptByDESModeEBC(ciphertext) {
        var keyHex = CryptoJS.enc.Utf8.parse(config.salt);
        var decrypted = CryptoJS.DES.decrypt({
            ciphertext: CryptoJS.enc.Hex.parse(ciphertext)
        }, keyHex, {
            mode: CryptoJS.moddesUtile.ECB,
            padding: CryptoJS.pad.Pkcs7
        });
        var result_value = decrypted.toString(CryptoJS.enc.Utf8);
        return result_value; //DES  ECB模式解密
    }
}
module.exports = desUtil;
