You can generate a self-signed certificate for development purposes using tools like OpenSSL or PowerShell on Windows, or even .NET's own APIs if you’re building the certificate within your .NET code. Here’s how to generate a self-signed certificate using these methods: Method 1: Generate a Self-Signed Certificate with OpenSSL Prerequisites: Make sure you have OpenSSL installed on your system. Generate a Private Key: openssl genpkey -algorithm RSA -out private.key -pkeyopt rsa_keygen_bits:2048 Generate a Ce
