Forum OpenACS Q&A: Re: AOLserver 4 not yet ready for prime time if you need SSL

nsopenssl is available from SourceForge CVS.  There are changes and bugfixes in HEAD that are newer than the tarballs that are on Scott's site.  You can view the ChangeLog and most recent sources online, see for example:
http://cvs.sourceforge.net/viewcvs.py/aolserver/nsopenssl/ChangeLog?view=markup

The SourceForge bug tracker for AOLserver has some nsopenssl items that are not fixed in even the HEAD sources.
