Converting PFX File to PEM file using OpenSSL in Windows 10

I am converting PFX File to .Pem file using OpenSSL in Windows 10.

Some Applications never allow .pfx files to import directly. Running the Ubuntu Bash shell becomes much simpler in Windows 10

In Windows 10, you can have a Linux subsystem. It’s a great feature for sys admins for these sorts of tasks.

Start – Run – Appwiz.cpl – Turn Windows Features on or off.

To Export the private key from the Pfx File and Make .PEM file –

openssl pkcs12 -in mycert.pfx -nocerts -out key.pem -nodes

To Export Certificate from the Pfx file to .PEM file –

openssl pkcs12 -in mycert.pfx -nokeys -out cert.pem
image

Remove the Passphrase from Key.Pem File (Optional) –

openssl rsa -in key.pem -out server.key

To Export to .crt

openssl pkcs12 -in mycert.pfx -clcerts -nokeys -out mycert.crt

Remove the Passphrase from Key.Pem File (Optional) –

You can see below files  –
