PKI and Digital Certificates Project in .NET 8

🔒🔑🛡️

Welcome to the PKI and Digital Certificates Project, where security meets innovation through robust cryptographic algorithms.

Overview

This project focuses on the study and implementation of Public Key Infrastructure (PKI) for secure digital communications. It includes:

• Generation of RSA key pairs for asymmetric encryption.
• Implementation of Diffie-Hellman for session key exchange.
• Utilization of symmetric encryption for secure data transmission.
• Digital signatures for data integrity and authenticity.

Features

• RSA Encryption: Securely generate and manage RSA key pairs.
• Diffie-Hellman Key Exchange: Facilitate secure key exchange using Diffie-Hellman algorithm.
• Symmetric Encryption: Encrypt and decrypt data using symmetric encryption methods.
• Digital Signatures: Generate and verify digital signatures for data integrity.
• BouncyCastle Integration: Utilize BouncyCastle library for key generation and cryptographic operations.

Components

• Certificate Authority (CA): Issue and manage digital certificates.
• Online Certificate Status Protocol (OCSP): Verify certificate revocation status.
• Certificate Revocation Lists (CRLs): Maintain lists of revoked certificates.
• Authority Information Access (AIA): Provide access to additional certificate information.

Installation

To get started with this project:

1. Clone the repository.
2. Install dependencies using NuGet, particularly BouncyCastle.
3. Explore and modify cryptographic operations as needed.
