We are compiling stunnel source without any
modification for different platform supported of our product. Then we are
running stunnel as a standalone process after making changes to stunnel.conf
file. In stunnel.conf file we are providing location of certificates and ports to
be used
We would distribute stunnel binary along with our product.
Given the scenario I have mentioned do you foresee legal problems in usage of
stunnel.
I understand that OpenSSL uses OpenSSL license but I
got this for openssl website.
====================================================
On many systems including the major
Linux and BSD distributions, yes (the GPL does not place restrictions on using
libraries that are part of the normal operating system distribution).
On other systems, the situation is
less clear. Some GPL software copyright holders claim that you infringe on
their rights if you use OpenSSL with their software on operating systems that
don't normally include OpenSSL.
If you develop open source software
that uses OpenSSL, you may find it useful to choose another license than the
GPL, or state explicitly that "This program is released under the GPL with
the additional exemption that compiling, linking, and/or using OpenSSL is
allowed." If you are using GPL software developed by others, you may want
to ask the copyright holder for permission to use their software with OpenSSL.
=====================================================
Specifically I am concerned if Stunnel states that compiling,
linking, and/or using OpenSSL is allowed

Subject: Stunnel License
Hi,
We are planning to use Stunnel to
encrypt traffic between Apache mod_jk and AJP connector of JBoss Tomcat.
It seems that Stunnel uses OpenSSL APIs.
Since Stunnel is available under GPL license, the license terms prevents us
from using Stunnel in our product since it exposes OpenSSL which is also
available under GPL license.
I would like to know if there is also a
commercial license available for stunnel? I would appreciate if you can throw
pointers on how to package Stunnel with a commercial product.
Thank
Gaurav
