ClientModul Project

Overview

The ClientModul project is designed to filter out unnecessary RSA certificates from a list of certificates. It ensures that if an ECC certificate from the same SMC-B is present, the corresponding RSA certificate is removed.

Features

• Filters RSA certificates if an ECC certificate with the same ICCSN is present.
• Handles certificates based on their validFrom date to ensure they are within a specified time window.
• Provides utility methods to handle certificate comparisons and filtering.

Prerequisites

• Java
• Gradle
• IntelliJ IDEA (recommended)

Getting Started

1. Clone the repository:

   git clone <repository-url>
   cd <repository-directory>

2. Open the project in IntelliJ IDEA:

   • Open IntelliJ IDEA.
   • Select File > Open and choose the cloned repository directory.

3. Build the project:

   ./gradlew build

4. Run the tests:

   ./gradlew test

Usage

To use the ClientModul class in the desired variant, instantiate it and call the weedOutUnnecessaryRsaCerts method with a list of certificates:

def clientModul = new ClientModul_<VariantNumber>()
def filteredCerts = clientModul.weedOutUnnecessaryRsaCerts(certs)
