I copied the following sample of using openssl to encrypt data.
Cannot post url fully so had to cut it down to this:
rtfm.com/openssl-examples/

I compiled the files fine. I can run the wclient and wserver samples fine when i run the wclient like this
$./wclient -i
This -i option means that it doesn't require the server to present a certificate. The problem arises when i run the program without the -i option. The program gets an error when opening the client.pem file. Do you need some special program to read these types of files. If not what is to be the problem?.
