Bitwasp Php Generate Private Key

PHP libraries implementing bitcoin key functions, as well as BIP32 and electrum.

NB: This library is outdated, and no longer maintained. BC breaks will not be accepted for this reason. For a newer library, please see

The library intends to expose a lot of general functionality which isn'tavailable using the RPC (like deterministic addresses).

  • Currently I have some working php code to generate a private/public keypair and store them in two variables. These variables are strings, with one variable containing the private key, and the other containing the public key. I researched on stack overflow and I also found some code to convert a pem encoded key string to a der encoded key string.

Generating the Public/Private Key Pair The first thing you need to do is generate your public/private key pair. This can be done in PHP but the little documentation I could find about the process only worked in PHP 5.3.0 or greater and I happen to be using a slightly older version.

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.

  • 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)

Installing via Composer (recommended)

  1. Install Composer in your project:

    curl -s php

  2. Create a composer.json file in your project root:

    {'require': {'bitwasp/bitcoin-lib': '1.0.*'}}

  3. Install via Composer

    php composer.phar install

Mcrypt Extension (Random data)

The Mcrypt Extension is required for generating random data, it does this internallyby using /dev/urandom on unix or CryptGenRandom on windows.

GMP Extension (Math)

Bitwasp Php Generate Private Key Generator

The GMP Extension is required for the crypto math.

PECL intl extension (BIP39)

The PECL intl extension is required for BIP39 Mnemonic Seeds when a UTF-8 passphrase is used.

Mdanter's PHP Pure PHP Elliptic Curve Cryptography Library

mdanter/ecc is required for most of the crypto.
