crypto 密码加密

'use strict';
var crypto = require('crypto');
/**
 * generates random string of characters i.e salt
 * @function
 * @param {number} length - Length of the random string.
 */
var genRandomString = function(length){
    return crypto.randomBytes(Math.ceil(length/2))
            .toString('hex') /** convert to hexadecimal format */
            .slice(0,length);   /** return required number of characters */
};
/**
 * hash password with sha512.
 * @function
 * @param {string} password - List of required fields.
 * @param {string} salt - Data to be validated.
 */
var sha512 = function(password, salt){
    var hash = crypto.createHmac('sha512', salt); /** Hashing algorithm sha512 */
    hash.update(password);
    var value = hash.digest('hex');
    return {
        salt:salt,
        passwordHash:value
    };
};
function saltHashPassword(userpassword) {
    var salt = genRandomString(16); /** Gives us salt of length 16 */
    var passwordData = sha512(userpassword, salt);
    console.log('UserPassword = '+userpassword);
    console.log('Passwordhash = '+passwordData.passwordHash);
    console.log('nSalt = '+passwordData.salt);
}
saltHashPassword('MYPASSWORD');
saltHashPassword('MYPASSWORD');

一、使用CBC模式

<script src="./js/crypto-js.js"></script>
<script src="./js/aes.js"></script>

<script>
    var key = '3132333435363738393041424344454631323334353637383930414243444566';
     console.log('密钥：', key);
     key = CryptoJS.enc.Hex.parse(key)
     iv = CryptoJS.enc.Hex.parse("30313233343536373839414243444546")
     var src = "werty7890";
     console.log('原字符串：', src);
     var enc = CryptoJS.AES.encrypt(src ,key,{
         iv:iv,
         mode: CryptoJS.mode.CBC,  
         padding: CryptoJS.pad.Pkcs7
     })

     //console.log('加密:',enc.toString());
     var enced = enc.ciphertext.toString()
     console.log("加密：", enced);

     var dec = CryptoJS.AES.decrypt(CryptoJS.format.Hex.parse(enced), key,{
         iv:iv,
         mode: CryptoJS.mode.CBC,  
         padding: CryptoJS.pad.Pkcs7
     })
     console.log('解密:',CryptoJS.enc.Utf8.stringify(dec));
</script>

二、使用ECB模式

<script src="./js/crypto-js.js"></script>
<script src="./js/aes.js"></script>

<script>
   var key = '3132333435363738393041424344454631323334353637383930414243444566';
   console.log('密钥：', key);
   key = CryptoJS.enc.Hex.parse(key)
   //iv = CryptoJS.enc.Hex.parse("30313233343536373839414243444546")
   //console.log('偏移量:',CryptoJS.enc.Hex.stringify(iv));
   var src = "werty7890";
   console.log('原字符串：', src);
   var enc = CryptoJS.AES.encrypt(src ,key,{
       //iv:iv,
       mode: CryptoJS.mode.ECB,  
       padding: CryptoJS.pad.Pkcs7
   })

   //console.log('加密:',enc.toString());
   var enced = enc.ciphertext.toString()
   console.log("加密：", enced);

   var dec = CryptoJS.AES.decrypt(CryptoJS.format.Hex.parse(enced), key,{
       //iv:iv,
       mode: CryptoJS.mode.ECB,  
       padding: CryptoJS.pad.Pkcs7
   })
   console.log('解密:',CryptoJS.enc.Utf8.stringify(dec));
</script>
