This SDK provides functionality to sign messages and more. Requirements ------------ [](#requirements) - PHP 7.4 or higher - Composer for managing dependencies - The `kornrunner/keccak` library for hashing - The `simplito/elliptic-php` library for elliptic curve operations Installation ------------ [](#installation) To use the Certhis SDK in your project, you'll need to install it via Composer. If you don't have Composer installed, you can download it from [getcomposer.org](https://getcomposer.org). ``` composer require "certhis/sdk" ``` ### 1. `Web3Helper::__construct($privateKey)` [](#1-web3helper__constructprivatekey) - **Purpose**: Initializes the `Web3Helper` instance with a given private key. This key is used for cryptographic operations such as signing messages. - **Parameters**: - `$privateKey`: A string representing the private key used for cryptographic operations. ### 2. `Web3Helper::getPublicKey()` [](#2-web3helpergetpublickey) - **Purpose**: Retrieves the public address associated with the private key provided during the initialization of the `Web3Helper` instance. - **Returns**: A string representing the public address. ### 3. `Certhis::__construct($api = 'https://api.certhis.io', $apikey = null)` [](#3-certhis__constructapi--httpsapicerthisio-apikey--null) - **Purpose**: Initializes the `Certhis` class, which serves as the main entry point for interacting with the Certhis API. - **Parameters**: - `$api` (optional): The base URL of the Certhis API. Defaults to `'https://api.certhis.io'`. - `$apikey` (optional): The API key used for authentication when making requests to the Certhis API. If not provided, the API key must be set later or within the environment. ### 4. `Sign::__construct($certhis)` [](#4-sign__constructcerthis) - **Purpose**: Initializes the `Sign` class, responsible for handling the signing and verification processes. - **Parameters**: - `$certhis`: An instance of the `Certhis` class, used to interact with the Certhis API. ### 5. `Sign::get($wallet)` [](#5-signgetwallet) - **Purpose**: Retrieves a signature from the Certhis API for a given wallet (public address). - **Parameters**: - `$wallet`: The public address for which the signature is requested. - **Returns**: An associative array containing the signature. ### 6. `Web3Helper::signMessage($message)` [](#6-web3helpersignmessagemessage) - **Purpose**: Signs a message using the private key associated with the `Web3Helper` instance. - **Parameters**: - `$message`: The message string to be signed. - **Returns**: The signed message. ### 7. `Sign::check($wallet, $signedMessage)` [](#7-signcheckwallet-signedmessage) - **Purpose**: Verifies that the signed message corresponds to the original signature retrieved from the Certhis API. - **Parameters**: - `$wallet`: The public address used to generate the original signature. - `$signedMessage`: The signed message to be verified. - **Returns**: A boolean value indicating whether the signed message is valid. Integration Example ------------------- [](#integration-example) Below is an example of how to integrate the Certhis SDK into your PHP project: ``` require '../vendor/autoload.php'; use Certhis\Sdk\Web3Helper; use Certhis\Sdk\Certhis; use Certhis\Sdk\Sign; // Initialize the Web3Helper instance with a private key $web3Helper = new Web3Helper('0xfc3f00a1acf34b12b38a91c89fc502b4851ed6f053be087b88286490966c7db0'); echo "Public address: " . $web3Helper->getPublicKey() . "\n"; // Initialize the Certhis class with an API key $certhis = new Certhis('https://api.certhis.io', 'your_api_key'); // Initialize the Sign class with the Certhis instance $sign = new Sign($certhis); // Get the public address from the Web3Helper $wallet = $web3Helper->getPublicKey(); // Retrieve a signature from Certhis API for the given wallet $get_sign = $sign->get($wallet); echo "Signature from Certhis: " . $get_sign["signature"] . "\n"; // Sign the retrieved message using Web3Helper $signed = $web3Helper->signMessage($get_sign["signature"]); echo "Signed Message: " . $signed . "\n"; // Verify the signed message using the Certhis Sign class $check = $sign->check($wallet, $signed); echo "Signature Verification Result: " . ($check ? "Valid" : "Invalid") . "\n"; ``` ### Health Score 19 — LowBetter than 9% of packages Maintenance33 Infrequent updates — may be unmaintained Popularity4 Limited adoption so far Community6 Small or concentrated contributor base Maturity30 Early-stage or recently created project Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
