The openssl.exe utility is installed by default in the directory Program Files\Micro Focus\DemoCA (Windows) or .The Windows directory is pointed to by the SSLDIR environment variable, which is created when you install this pack. The directory is not automatically added to your path, but you might find it useful to add it.
The openssl utility supplied with this pack is a full implementation of the utility, except that certain algorithms that we believe to be subject to patents or other legal restrictions have been excluded.
You run openssl from the command line.
