This article introduces the relevant knowledge of "how to use the ethernet mnemonic PHP development kit". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. Overview of the development package

The ethernet mnemonic PHP package mainly includes the following features:

Generate mnemonic words that conform to the BIP39 standard

Convert BIP39 mnemonic words to hierarchical determination keys that conform to the BIP32 standard

Support BIP44 multi-currency level deterministic wallet specification

Mnemonic words and key / address conversion compatible with imtoken, metamask and other common wallets

2. Instructions for using the core class

The Mnemonic class is the entry class of the Ethernet mnemonic PHP package, which is used to generate mnemonic words that conform to the BIP39 standard, or to convert existing mnemonic words into corresponding random entropy values for the generation of private keys.

The Mnemonic class provides the following static methods for instantiation:

New (): create a new Mnemonic object

FromWords (): instantiate Mnemonic objects with existing mnemonics

FromEntropy (): instantiates Mnemonic objects using existing random entropy

Mnemonic examples provide the following methods to obtain random entropy and mnemonics of their representations:

GetEntropy (): get random entropy

GetWords (): get mnemonic words

The HDKey class is used to create a hierarchical determination key that supports the BIP32/BIP44 standard and provides the following static method instantiation:

FromMnemonic (): use mnemonics to create levels to determine the master key

FromSeed (): use seed data to create a hierarchy to determine the master key

The HDKey instance object provides the following methods to derive descendant HDKey:

DeriveChild (): derives the subkey of the specified sequence number

DerivePath (): derives the descendant key of the specified hierarchical path

3. Sample code: generate new mnemonic words

The following code uses the static method new () of the Mnemonic class to generate new mnemonics, and then outputs and displays the generated mnemonics and their corresponding random entropy:

Use EthTool\ Mnemonic;$mnemonic = Mnemonic::new (); / * create a new mnemonic * / echo 'mnemonic = >'. $mnemonic- > getWords (). PHP_EOL; / * displays the mnemonic * / echo 'entropy = >'. $mnemonic- > getEntropy (). PHP_EOL; / * shows the corresponding random entropy * /

Use mnemonics to generate a hierarchical master key and determine the wallet's first Ethernet Fong key and address according to the BIP44 convention generation level:

$master = HDKey::fromMnemonic ($mnemonic- > getWords ()); / * generate the BIP32 hierarchical master key using mnemonics * / $key0 = $master- > derive ("m _ max 44 cents / 60 cents); / * generate the first hierarchical key corresponding to the Ethernet Fong key path of the BIP44 agreement * / echo 'key = >'. $key0- > privateKey. PHP_EOL; / * displays the private key corresponding to the hierarchical key, hexadecimal string * / echo 'address = >'. $key0- > address. PHP_EOL; / * display the ethernet address corresponding to the hierarchical key * / 4, sample code: import existing mnemonics

The following code uses the static method fromWords () of the Menmonic class to import the existing mnemonic, and then uses the mnemonic to generate the corresponding hierarchical key and BIP44 ethernet wallet address:

Use EthTool\ HDKey;// mnemonic $words = 'moral predict wash pledge hybrid box virtual length clap volcano shadow notice';$master = HDKey::fromMnemonic ($words); / * use mnemonics to generate a BIP32-level master key * / $key0 = $master- > derive ("m-pinch-44-pound-60-pound-0-pound-0-pound"); / * generate the first hierarchical key corresponding to the Ethernet Fong key path of the BIP44 agreement * / echo' private key = >'. $key0- > privateKey. PHP_EOL; / * displays the private key corresponding to the hierarchical key, hexadecimal string * / echo 'address = >'. $key0- > address. PHP_EOL; / * shows the Ethernet Square address corresponding to the hierarchical key * / "how to use the Ethernet Square mnemonic PHP Development Kit". Thank you for your reading.
