BIP39 (Mnemonic code for generating deterministic keys)
=======================================================

[](#bip39-mnemonic-code-for-generating-deterministic-keys)

PHP implementation of [BIP-0039](./bip-0039.mediawiki) supporting:

- Generate mnemonic (12–24 words) from secure random entropy
- Convert provided entropy (hex) to mnemonic
- Convert mnemonic back to original entropy (checksum verified)
- Derive seed (512-bit) from mnemonic + optional passphrase (PBKDF2-HMAC-SHA512 / 2048 rounds)
- Validate mnemonics
- All official BIP-39 wordlists (English, Chinese (Simplified & Traditional), Czech, French, Italian, Japanese, Korean, Portuguese, Spanish)
- Unicode NFKD normalization (when `ext-intl` is available)

Installation
------------

[](#installation)

```
composer require nyra/bip39
```

(For development / running tests clone the repo and run `composer install`.)

Optional: install `ext-intl` for full Unicode NFKD normalization; a graceful fallback is used if missing.
