Crates.io Downloads Documentation License Dependency Status

ferropassgen is a Rust library for generating strong and secure passwords and passphrases. It provides a flexible and customizable password generation framework that can be easily integrated into other Rust projects.

Features

  • Generate strong passwords with customizable length and character sets
  • Generate memorable passphrases with customizable length, word list, separator, and word case
  • Lightweight and fast password generation
  • Extensible and customizable password generation traits
  • Well-documented API with examples and error handling

Usage

To use ferropassgen in your Rust project, add the following to your Cargo.toml:

[dependencies]
ferropassgen = "0.1.0"

Then, import the necessary modules and structs in your Rust code:

use ferropassgen::{PassGen, PasswordGen, PassphraseGen, PassGenError};

Generating Passwords

To generate a password, create an instance of PasswordGen and call the generate method:

let length = 16;
let charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*".chars().collect::<Vec<char>>();
let password_gen = PasswordGen::new(length, charset, None, None)?;
let password = password_gen.generate();

Generating Passphrases

To generate a passphrase, create an instance of PassphraseGen and call the generate method:

let length = 4;
let wordlist = vec!["apple", "banana", "cherry", "date", "elderberry"]
    .iter()
    .map(|&s| s.to_string())
    .collect::<Vec<String>>();
let separator = Some('_');
let word_case = Some(true);
let passphrase_gen = PassphraseGen::new(length, wordlist, separator, word_case)?;
let passphrase = passphrase_gen.generate();

Error Handling

The new methods of PasswordGen and PassphraseGen return a Result<Self, PassGenError>. Make sure to handle the potential errors appropriately.

Examples

Here are a few examples of using ferropassgen to generate passwords and passphrases:

use ferropassgen::{PassGen, PasswordGen, PassphraseGen};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Generate a 20-character password with a custom character set
    let length = 20;
    let charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".chars().collect::<Vec<char>>();
    let password_gen = PasswordGen::new(length, charset, None, None)?;
    let password = password_gen.generate();
    println!("Generated Password: {}", password);

    // Generate a passphrase with 5 words, separated by underscores, and in uppercase
    let length = 5;
    let wordlist = vec!["apple", "banana", "cherry", "date", "elderberry"]
        .iter()
        .map(|&s| s.to_string())
        .collect::<Vec<String>>();
    let separator = Some('_');
    let word_case = Some(true);
    let passphrase_gen = PassphraseGen::new(length, wordlist, separator, word_case)?;
    let passphrase = passphrase_gen.generate();
    println!("Generated Passphrase: {}", passphrase);

    Ok(())
}
