Cygwin ran the gentls_cert scripts perfectly on Windows 7 using Cygwin 1.7.13-1 Thanks again Mitch! -----Original Message----- From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Mitch Capper Sent: Tuesday, April 10, 2012 11:52 PM To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] generating TLS client certificates on Windows It should not involve much reverse engineering as gentls_cert is pretty simple and the commands are the same in windows as linux. Also there is nothing magical about the certificates FS uses so googling: https://encrypted.google.com/search?q=openssl%20windows%20client%20certifica te&ie=UTF-8&oe=UTF-8 Should give decent results and guides, however to help I have attached the openssl config file that gentls_cert produces which should give you 90%. A fairly low bounty could probably get a .net openssl wrapper for certificate generation made also. Finally keep in mind cygwin with openssl would probably allow gentls to work out of the box too. ~Mitch
