Converting a PFX to JKS in C# Using Bouncy Castle

  Converting a PFX to JKS in C# Using Bouncy Castle When working with cryptographic operations, you might encounter scenarios where you need to convert a certificate stored in PFX (Personal Information Exchange) format to a JKS (Java KeyStore) format. In this blog post, we'll explore how to achieve this conversion in C# using the Bouncy Castle library. Prerequisites Before we begin, make sure you have the following: The PFX file containing your certificate. The password for the PFX file. A development environment with C# support. Access to the Bouncy Castle library. Step 1: Set Up Your C# Project Start by creating a new C# console application in your preferred development environment. Ensure that you have added the Bouncy Castle library to your project. bash Copy code dotnet add package BouncyCastle.NetCore Step 2: Write the Conversion Code Now, let's write the C# code to convert the PFX to JKS using the Bouncy Castle library. csharp Copy code using System; using System.IO; usi...

Completing the SSL Certificate Request in C#

  Completing the SSL Certificate Request in C# with Certificate Reply from a Certificate Authority (CA) After generating a Certificate Signing Request (CSR), the next step is to complete the process by obtaining a signed certificate from a Certificate Authority (CA). In this blog post, we'll explore how to finalize the CSR using C# and integrate the CA's certificate reply into your application. Prerequisites Before you proceed, make sure you have: The CSR generated from the previous steps. Received the CA's certificate reply in PEM format. Step 1: Update Your C# Application Modify your existing C# console application to include the code for completing the CSR with the CA's certificate reply. csharp Copy code   using System; using System.Security.Cryptography.X509Certificates; class Program {     static void Main()     {         try         {             // Load the existing private key an...
