Rust program to generate a random password

Generate a random password

Rust Programming Language

Problem

In this program, we will generate a random password and print generated password on the console screen.

Add random external library to your project

Create your project using the below command.

$cargo new random --bin{codeBox}

Goto the project folder cd random and edit Cargo.toml file.

$random>nano Cargo.toml{codeBox}

Then add dependency in Cargo.toml file

[dependencies]

rand = "0.5.5"{codeBox}

After that, build your project using the below command

$random>cargo build{codeBox}

Then execute your project after modification in the src/main.rs source file.

$random>cargo run{codeBox}

Input

// Rust program to generate a 

// random password

use rand::{thread_rng, Rng};

use rand::distributions::Alphanumeric;

fn main() {

    let password: String = thread_rng()

        .sample_iter(&Alphanumeric)

        .take(10)

        .map(char::from)

        .collect();

        

    println!("Generated password: {}", password);

}{codeBox}

Output

$random> cargo run

Generated password: AUg2u0JJNx{codeBox}

Explanation

In the above program, we imported the "rand" library to our project for generating random numbers. We imported the "rand" library using the below line:

use rand::Rng;{codeBox}

In the main() function, we generated a random password using rand library functions and printed the result.
