This project is intended to create a free Windows based UI for command line openssl operations. Currently a UI has been developed with Windows WPF. Existing code needs some code cleanups. The source and binaries are available for download.
Thanks for this tool.
For your information, the current release (2013-04-09) does not manage
CA certificate creation (and possibly others) if the name have a space in it.
Using the command line, you probably just need to add quotes to the argument passed as parameter to solve this issue.
