The openssl.exe utility is installed by default in the directory: %ProgramFiles(x86)%\Micro Focus\DemoCA (Windows) or /opt/microfocus/DemoCA or $COBSSL (if set) (UNIX). This directory is pointed to by the SSLDIR environment variable, which is created when you install this pack (Windows). 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 are subject to patents or other legal restrictions have been excluded. See Supported Algorithms in the Readme for a list of the supported algorithms.
You can run openssl from the command line.
For details of the OpenSSL utility, see www.openssl.org and www.mkssoftware.com.
