This package provides easy-to-use methods for securing your data through signatures, ensuring authenticity and integrity. Installation ------------ [](#installation) You can install the package via Composer by running the following command in your Laravel project: ``` composer require jmrashed/laravel-cryptographic-signatures ``` ### Publishing Configuration [](#publishing-configuration) Publish the package's configuration file to customize your keys: ``` php artisan vendor:publish --provider="Jmrashed\LaravelCryptographicSignatures\Providers\CryptoSignaturesServiceProvider" --tag="config" ``` This will create a `cryptosignature.php` file in the `config/` directory, where you can specify the paths to your private and public keys. ### Configuration [](#configuration) In your `.env` file, set the paths to your private and public keys: ``` CRYPTO_PRIVATE_KEY=storage/keys/private.key CRYPTO_PUBLIC_KEY=storage/keys/public.key ``` How to generate RSA keys: storage/keys/private.key and storage/keys/public.key ``` openssl genrsa -out storage/keys/private.key 2048 openssl rsa -in storage/keys/private.key -pubout -out storage/keys/public.key ``` Make sure your keys are stored securely in the specified paths. ### How to publish config and keys [](#how-to-publish-config-and-keys) ``` php artisan vendor:publish --provider="Jmrashed\LaravelCryptographicSignatures\Providers\CryptoSignaturesServiceProvider" --tag="config" php artisan vendor:publish --provider="Jmrashed\LaravelCryptographicSignatures\Providers\CryptoSignaturesServiceProvider" --tag="keys" ``` Usage ----- [](#usage) Once the package is installed and configured, you can easily generate and verify cryptographic signatures. ### Generating a Signature [](#generating-a-signature) Use the `CryptoSignature` facade to generate a signature for your data. ``` use Jmrashed\LaravelCryptographicSignatures\Facades\CryptoSignature; $data = 'Sensitive data to be signed'; $signature = CryptoSignature::generateSignature($data); echo "Generated Signature: " . $signature; ``` ### Verifying a Signature [](#verifying-a-signature) You can also verify a signature to ensure the integrity and authenticity of the data. ``` use Jmrashed\LaravelCryptographicSignatures\Facades\CryptoSignature; $data = 'Sensitive data to be verified'; $signature = 'previouslyGeneratedSignature'; $isVerified = CryptoSignature::verifySignature($data, $signature); if ($isVerified) { echo "The signature is valid!"; } else { echo "The signature is invalid!"; } ``` Features -------- [](#features) - **Generate cryptographic signatures**: Safely sign your data with a private key. - **Verify signatures**: Ensure the authenticity and integrity of data with a public key. - **Flexible configuration**: Easily set custom key paths through Laravel’s config system. Example ------- [](#example) Here’s a complete example that demonstrates generating and verifying a signature: ``` use Jmrashed\LaravelCryptographicSignatures\Facades\CryptoSignature; $data = 'Sensitive data to be signed'; // Generate the signature $signature = CryptoSignature::generateSignature($data); // Verify the signature $isVerified = CryptoSignature::verifySignature($data, $signature); if ($isVerified) { echo "The data is verified!"; } else { echo "Signature verification failed!"; } ``` Testing ------- [](#testing) To run tests for the package, use the following command: ``` php artisan test ``` Make sure your keys are properly configured in the `.env` file before running the tests. License ------- [](#license) The package is open-sourced software licensed under the [MIT license](LICENSE). Contributing ------------ [](#contributing) Contributions are welcome!
