pqbip39

A no_std compatible Rust implementation of the BIP-39 mnemonic code standard for generating and validating mnemonic phrases used in cryptocurrency wallets.

Features

• Supports 12 to 33-word mnemonic phrases
• Generates seeds from mnemonics using PBKDF2
• Validates checksums and word counts
• Converts between entropy and mnemonic phrases
• Compatible with no_std environments
• Optional std and zeroize features

Installation

Add the following to your Cargo.toml:

[dependencies]
pqbip39 = "0.1.0"

Usage

Generating a Mnemonic

use pqbip39::{Mnemonic, rng::Rng};
use rand::rngs::OsRng;

const EN_WORDS: [&str; 2048] = [/* English BIP-39 wordlist */];

let mut rng = OsRng;
let mnemonic = Mnemonic::generate(&mut rng, &EN_WORDS, 12).unwrap();
println!("{}", mnemonic); // e.g., "abandon ability able ..."

Parsing a Mnemonic

use pqbip39::Mnemonic;

const EN_WORDS: [&str; 2048] = [/* English BIP-39 wordlist */];

let phrase = "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about";
let mnemonic = Mnemonic::parse_str(&EN_WORDS, phrase).unwrap();

Converting to Seed

let seed = mnemonic.to_seed("TREZOR").unwrap();

Converting to Entropy

let entropy: Vec<u8> = mnemonic.to_entropy().collect();

Features

• std: Enables std library features like Unicode normalization (default).
• zeroize: Adds secure zeroing of sensitive data.

To disable std (for no_std):

[dependencies]
pqbip39 = { version = "0.1.0", default-features = false }

Testing

Run tests with:

cargo test

The library includes comprehensive tests for entropy conversion, checksum validation, and PBKDF2 seed generation, including BIP-39 test vectors.
