FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

BIP39 Mnemonic

Mnemonic BIP39 implementation in PHP

Installation

Prerequisite

Composer

composer require xiaohuasheng0x1/bip39-php

Mnemonic Object

This lib will create this Mnemonic object as a result:

Prop Data Description
entropy string Hexadecimal representation of binary Entropy bits
wordsCount int Number of words (12, 15,18, 21 or 24)
wordsIndex array Indexed array (of integers) indexes from wordlist
words array Indexed array of mnemonic codes
rawBinaryChunks array Indexed array of binary bits (1s and 0s) each containing 11 bits according to BIP39 Spec

Generate Mnemonic Codes (12, 15, 18, 21 or 24 words)

Generate mnemonic of 12, 15, 18, 21 or 24 words using an entropy driven from cryptographically secure pseudo-random bytes.

Generate Mnemonic using specified Entropy

Specify your own entropy to generate mnemonic codes:

Reverse (Mnemonic to Entropy)

Use mnemonic codes to find entropy. By default, lib will cross-check checksum therefore not using valid mnemonic codes will throw an exception.

Generate non-english mnemonic codes

Mnemonic codes may be generated in ALL languages supported in BIP39 spec. This example generates 12 mnemonic codes in Spanish language as an example, and it may be replaced with other any other language with wordlists in BIP39 spec, check here.
