Step 2: Create a private key
For this example, we are going to create a private key called usoftca.key. Note that in this version, if you make your own key you must also use this file name:
Open a DOS (command prompt) window and change directory to \openssl\bin or the \bin subfolder of your OpenSSL installation location.
openssl genrsa -des3 -out usoftca.key 4096
NOTE: You must use the filenames specified in these examples.
You should see something like the following:
Provide a pass phrase, and remember it! You will need it later in the procedure.
You should now have a file called usoftca.key in the \bin subfolder of your OpenSSL installation location.
