The OpenSSL (openssl) tool

The openssl command line tool creates certificates for the configuration of secured communications.

OpenSSL is provided in the FGLGWS package. To use it, you need to add its directory, $FGLDIR/web_utilities/tools, to your PATH environment variable.

The openssl tool has a default configuration file, openssl.cnf. It looks for the openssl.cnf file in the directory where it is executed; it stops if the file is not present. To use the openssl tool from any directory, set the OPENSSL_CONF environment variable to specify the location of the configuration file.

For information on how the openssl tool works, refer to the openssl documentation.
