Implementation of raw transactions in bitcoin, HD wallets, Electrum wallets, and other fun stuff.

bitcoin-lib-php

PHP libraries implementing bitcoin key functions, as well as BIP32 and electrum., _(*1)

, _(*2)

NB: This library is outdated, and no longer maintained. BC breaks will not be accepted for this reason. For a newer library, please see https://github.com/Bit-Wasp/bitcoin-php, _(*3)

The library intends to expose a lot of general functionality which isn't available using the RPC (like deterministic addresses)., _(*4)

It also allows you to reduce the number of queries that are made to bitcoind, such as createrawtransaction/signrawtransaction/decoderawtransaction. As such, such, use of bitcoin RPC functionality can be kept to a minimum., _(*5)

Libraries

• Raw Transactions: create, sign, validate, with support for P2SH.
• Create multi-signature addresses, create redeeming transactions.
• BIP32: Functions for generating BIP32 deterministic keys.
• Electrum: Create seed from mnemonic, create MPK from seed, derive public keys from MPK, or private keys from seed.
• BitcoinLib: The core class, with key functionality, encoding/decoding & validation functions, etc.
• BIP39: Functions for generating Mnemonic code for generating deterministic keys (possibly password protected)

If this library powers your project and you're feeling tipsy, buy me lunch some day! 1sCVtkEhQmvp3D4K22Pw9xhFPTDWFh8SZ, _(*6)

Installation

Installing via Composer (recommended)

1. Install Composer in your project:, _(*7)

   curl -s http://getcomposer.org/installer | php, _(*8)

2. Create a composer.json file in your project root:, _(*9)

   { "require": { "bitwasp/bitcoin-lib": "1.0.*" } }, _(*10)

3. Install via Composer, _(*11)

   php composer.phar install, _(*12)

Dependencies

Mcrypt Extension (Random data)

The Mcrypt Extension is required for generating random data, it does this internally by using /dev/urandom on unix or CryptGenRandom on windows., _(*13)

GMP Extension (Math)

The GMP Extension is required for the crypto math., _(*14)

PECL intl extension (BIP39)

The PECL intl extension is required for BIP39 Mnemonic Seeds when a UTF-8 passphrase is used., _(*15)

Mdanter's PHP Pure PHP Elliptic Curve Cryptography Library

mdanter/ecc is required for most of the crypto., _(*16)
