*Convert .pem certificate into .pfx
To convert a .pem certificate to .pfx, follow these steps:
1. Ensure you have OpenSSL installed.
2. Prepare the required files:
◦ .pem certificate file (certificate.pem)
◦ Private key file (privatekey.pem)
◦ (Optional) CA chain file (ca-chain.pem)
3. Run the following command to create the .pfx file:

openssl pkcs12 -export -out certificate.pfx -inkey privatekey.pem -in certificate.pem -certfile ca-chain.pem

4. When prompted, enter a password to secure the .pfx file.
5. Verify the .pfx file using:

openssl pkcs12 -info -in certificate.pfx

This process combines the certificate, private key, and CA chain (if provided) into a .pfx file, which is commonly used for secure applications like Windows servers or browser-based authentication.
