Hi! HIPL uses the OpenSSL toolkit which is covered by a mix of the Apache 1.1 license and a custom license. It has the usual requirements on copyright notices and disclaimers being present in derived work, but I could not find any of that in any part of HIPL. Also, the the GPLv2 license is incompatible at least with the Apache 1.1 license. I'm not sure what the implications of this situation are but it might scare off potential users of HIPL.
