How To Use Vue-Cryptojs in Vue.js

In this article, we will learn how to use cryptojs in vue.js

Step 1: Create a new Vue project:

vue create vue-cryptojs-demo

Step 2: Install require packages:

npm i vue-cryptojs

Step 3: Open main.js file and add following in it:

import { createApp } from 'vue'
import App from './App.vue'
import VueCryptojs from 'vue-cryptojs'

createApp(App).use(VueCryptojs).mount('#app')

Step 4: Open App.vue file and add following in it:

<template>
   <input v-model="pvtData" placeholder="Enter a string" />
    <button @click="encryptData">Encrypt</button>
    <button @click="decryptData">Decrypt</button>
    <button @click="deleteData">Delete</button>
    <p v-if="encData">Encrypt Data: {{ encData }}</p>
    <p v-if="decData">Decrypt Data: {{ decData }}</p>
</template>

<script>

export default {
  name: 'App',
  data() {
    return {
      pvtData: "",
      secret: "123#$%",
      encData: "",
      decData:""
    };
  },
  methods: {
  encryptData() {
      if (this.pvtData.length) {
        const data = this.$CryptoJS.AES.encrypt(this.pvtData, this.secret).toString();
        localStorage.setItem("secretData", data);
        this.getEncryptedData();
      }
    },

    decryptData() {
      const secretData = localStorage.getItem("secretData");
      const decryptData = this.$CryptoJS.AES.decrypt(
        secretData,
        this.secret
      ).toString(this.$CryptoJS.enc.Utf8);

      this.decData = decryptData;
    },

    deleteData() {
      localStorage.removeItem("secretData");
      this.decData = "";
      this.getEncryptedData();
      this.encData = "";
      this.pvtData = "";
    },

    getEncryptedData() {
      this.encData = localStorage.getItem("secretData") || "Value not availbale";
    },
  },
}
</script>

<style>
#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
