Vue Js Generate Hash Password:Vue.js is a front-end JavaScript framework that allows developers to build web applications. One of the common tasks when building web applications is to generate a hash password, which can be done using a built-in method in JavaScript called crypto.subtle.digest(). This method takes the password string as input, then generates a hash of the password using a cryptographic hash function, such as SHA-256. The resulting hash can be stored in a database instead of the actual password, which provides an additional layer of security in case of a data breach. Vue.js can easily integrate this method into its components and provide a secure way to store and manage user passwords.

How can Vue Js be used to generate a hash password?

The code you provided is a Vue.js method for generating a hash password using the SHA-256 algorithm. Here is a brief explanation of how it works:

1. The method takes the value of the password from the this.password property.
2. The TextEncoder constructor is used to create an encoder object for converting the password to a Uint8Array.
3. The encoder.encode() method is called with the password as its parameter to convert the password to a Uint8Array.
4. The crypto.subtle.digest() method is used to generate a hash of the password using the SHA-256 algorithm.
5. The await keyword is used to wait for the promise returned by the digest() method to be resolved.
6. The resulting hash is returned as an ArrayBuffer object.
7. The Array.from() method is used to convert the ArrayBuffer to an array of bytes.
8. The map() method is used to convert each byte to its hexadecimal representation.
9. The padStart() method is used to ensure that each hexadecimal representation has two characters.
10. The resulting array of hexadecimal representations is joined into a single string using the join() method.
11. The resulting hash password string is assigned to the this.hashPassword property.

Overall, this method takes a plaintext password and generates a hashed password using the SHA-256 algorithm, which is commonly used for secure password storage.

Vue Js Generate Hash Password Example

 <div id="app">
        <form @submit.prevent="generateHashPass">
            <label for="password">Password:</label>
            <input type="password" id="password" v-model="password" />
            <button type="submit">Generate Hash Password</button>
            <small v-if="hashPassword">Hash Password: {{hashPassword}}</small>
        </form>
    </div>
    <script type="module">
        const app = new Vue({
            el: "#app",
            data() {
                return {

                    password: "123456789",
                    hashPassword: ''
                };
            },
            methods: {
                async generateHashPass() {
                    const password = this.password;
                    const encoder = new TextEncoder();
                    const data = encoder.encode(password);
                    const hash = await crypto.subtle.digest("SHA-256", data);
                    const hashArray = Array.from(new Uint8Array(hash));
                    const hashHex = hashArray.map((b) => b.toString(16).padStart(2, "0")).join("");
                    this.hashPassword = hashHex


                },
            },
        })
    </script>
