OpenSSL is not the 3 clause BSD license, it also includes a number of
advertising clauses that the GPL has never liked -- GPL must not be
modified for derivatives but the advertising clauses are in addition to
the GPL, so it must be modified for the combination.

Exceptions exist in the GPL for libraries and tools included in the
operating system and this is enough in most cases. GPL applications on
Windows may have problems.

2. Can I use OpenSSL with GPL software?

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 an other 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.
