Overview 📖

PassPhrase (PSPH) is a Rust library that empowers developers to elevate the security of their applications with ease. PSPH generates secure and strong passphrases using a unique combination of letters, numbers, cases, and symbols to form an unpredictable string of characters that doesn't resemble words or names with a high level of entropy.

Features ✨

PSPH uses the cmn crate for constants; the hsh crate for password hashing, and the vrd crate for random number generation.

The Password struct is the cornerstone of PSPH, storing the generated passphrase, as well as the optional special characters and separators to use. This struct also provides a range of functions for evaluating the security of the password, such as entropy calculation, hash generation, password validation, and much more.

  • Passphrase Generation: Generates random, secure passphrases consisting of multiple words separated by a specified separator.
  • Entropy Calculation: Calculates the entropy of a password based on its length, the number of unique characters used, and the number of bits of the hash generated from the password. The entropy value provides insight into the security of the password, with higher entropy values indicating stronger security.
  • Hash Generation: Returns the hash of the generated password,
  • enabling secure storage of the passphrase.
  • Hash Length Calculation: Evaluates the length of the hash generated from the password.
  • Passphrase Validation: Checks if the generated passphrase is empty, making sure that a secure password is always generated.
  • Passphrase Length Calculation: Evaluates the length of the generated passphrase, giving developers full control over password length.

Installation đŸ“Ļ

It takes just a few minutes to get up and running with psph.


psph requires Rust 1.67.0 or later.


ℹī¸ Info: Please check out our website for more information and find our documentation on, and

Usage 📖

To use psph in your project, add the following to your Cargo.toml file:

psph = "0.0.1"

Add the following to your file:

extern crate psph;
use psph::*;

then you can use the functions in your application code.


PSPH comes with a set of examples that you can use to get started. The examples are located in the examples directory of the project. To run the examples, clone the repository and run the following command in your terminal from the project root directory.

cargo run --example psph
