In ubuntu: ``` sudo apt install php7.0-gmp ``` ### From repository [](#from-repository) You also can clone git package with ``` git clone https://github.com/hdfchain/hdfchain-php-api.git ``` But still you will need to fetch library dependencies with [composer](https://getcomposer.org/doc/00-intro.md). ``` composer install --no-dev ``` Don't forget to include composer autoloader. ``` include __DIR__.'/../vendor/autoload.php'; ``` Usage examples -------------- [](#usage-examples) Library have wide functionality, so you could find usage examples in `examples` library or looking into PHPUnit tests. ### Generating seed [](#generating-seed) First of all we need to get Network intance to start working with library. ``` $testnet = \Hdfchain\TestNet::instance(); ``` And mainnet accordingly ``` $mainnet = \Hdfchain\MainNet::instance(); ``` Now lets generate a seed, that will be also verified for usage on testnet. Defaut account and branch address will be derivded to verify the seed. ``` $seed = \Hdfchain\Crypto\ExtendedKey::generateSeed($testnet); ``` ### HD Wallets [](#hd-wallets) When we have usable seed we can create HD master key. ``` $master = \Hdfchain\Crypto\ExtendedKey::newMaster($seed, $testnet); ``` `newMaster` method will return `ExtendedKey` object, that have variant API for working with HD wallets. #### `ExtendedKey::privateChildKey($index)` [](#extendedkeyprivatechildkeyindex) Derives HD private child key from parent HD private key, returns `ExtendedKey` object. #### `ExtendedKey::hardenedChildKey($index)` [](#extendedkeyhardenedchildkeyindex) Derives HD hardened child key from parent HD private key, returns `ExtendedKey` object. Can't be dervied from HD public key. #### `ExtendedKey::publicChildKey($index)` [](#extendedkeypublicchildkeyindex) Derives HD public child key from parent HD private or public key, returns `ExtendedKey` object. #### `ExtendedKey::neuter` [](#extendedkeyneuter) Verify that extended key is public, returns `ExtendedKey` object. ### Default account [](#default-account) Using this basic methods we can derive default account HD private and public keys accourding to [BIP44](https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki). HD path (m\\44'\\42'\\0') ``` $defaultAccountPrivateKey = $master ->hardenedChildKey(44) ->hardenedChildKey(42) ->hardenedChildKey(0); $defaultAccountPublicKey = $master->neuter(); ``` `ExtendedKey` implements `__toString()` method, so you can easily get Base58 representation of HD key. ``` echo sprintf("Default account HD private key: %s\n", $defaultAccountPrivateKey); echo sprintf("Default account HD public key: %s\n", $defaultAccountPublicKey); ``` From default account we can derive 0 branch and 0 index and the get default address. ``` $defaultAddress = $defaultAccountPublicKey ->publicChildKey(0) ->publicChildKey(0) ->getAddress(); echo sprintf("Default address: %s\n", $defaultAddress); ``` ### Health Score 23 — LowBetter than 27% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity6 Limited adoption so far Community9 Small or concentrated contributor base Maturity49 Maturing project, gaining track record Bus Factor1 Top contributor holds 75% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
