Vue Js encryption decryption String using crypto js:Vue.js is a popular JavaScript framework used for building user interfaces. To encrypt and decrypt strings in Vue.js using Crypto.js, you can follow a few simple steps. First, import the necessary libraries for Vue.js and Crypto.js. Then, define a key and an initialization vector (IV) for encryption. Next, use the Crypto.js library to encrypt the string by passing the key, IV, and the string to be encrypted. To decrypt the encrypted string, again use Crypto.js and provide the key, IV, and the encrypted string. By following these steps, you can easily encrypt and decrypt strings in Vue.js using the Crypto.js library.

How can I encrypt and decrypt a string in Vue.js using Crypto.js?

The code snippet demonstrates how to encrypt a string in Vue.js using the CryptoJS library.

Vue.js is a JavaScript framework used for building user interfaces, and CryptoJS is a popular JavaScript library for cryptographic functions. In this example, a Vue instance is created with a data object containing three properties: stringToEncrypt, secretKey, and encryptedString.

The encryptString method is defined, which utilizes the CryptoJS.AES.encrypt function to encrypt the stringToEncrypt using the secretKey. The resulting encrypted string is then stored in the encryptedString property.

By calling the encryptString method, the encryption process is triggered and the encrypted string is generated and stored, ready for further use or transmission.

Vue Js encryption decryption String using crypto js Example

 <script type="module">
    const app = new Vue({
      el: "#app",
      data() {
        return {
          stringToEncrypt: 'password',
          secretKey: 'mySecretKey',
          encryptedString: '',
        };
      },
      methods: {
        encryptString() {
          this.encryptedString = CryptoJS.AES.encrypt(
            this.stringToEncrypt,
            this.secretKey
          ).toString();
        },
      },
    });
  </script>

How can I decrypt a string using Crypto js in Vue.js?

The given code snippet demonstrates how to decrypt a string using Vue.js and the CryptoJS library.

In the code, a Vue instance is created with the el property set to “#app”. The instance has a data object that contains the encryptedString, secretKey, and decryptedString variables.

The decryptString method is defined, which uses the CryptoJS.AES.decrypt function to decrypt the encryptedString using the secretKey. The decrypted result is obtained as bytes and then converted to a UTF-8 string using the toString method.

    },
    methods: {
        decryptString() {
            const decryptedBytes = CryptoJS.AES.decrypt(
                this.encryptedString,
                this.secretKey
            );
            this.decryptedString = decryptedBytes.toString(CryptoJS.enc.Utf8);
        },
    },
});
</script>
