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.

Go to Step 3: Create a master certificate based on private key
