cmd - openssl hangs and does not exit

Question

I am trying to use openssl to get a certificate, and it seems to keep hanging. I have done a lot of research but not all of the available options seem to work on Windows.

openssl s_client -showcerts -connect google.com:443 > cert.txt

I have tried this:

openssl s_client -connect xyz:443 < quit.txt > cert.txt

Where quit.txt contains "quit " from http://bytes.com/topic/php/answers/8802-automate-openssl-s_client-command-batch-php-script

That did not work. I also looked at Openssl s_clinet -connect scripting. Force quit help

I have also tried -prexit

I have also looked into this as well and can't get it working: https://serverfault.com/questions/139728/how-to-download-ssl-certificate-from-a-website

I was doing so well! I managed to do something that I thought would be impossible and a simple thing like this bug managed to stop me for the time being :(

On windows, simply typing winpty before your openssl command will do the trick. So, for example, you could create a certificate like so:

winpty openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days XXX
