Hello Panlst, The answer to your question is 'No' under your conditions. In general, following are the options: 1. Use a certificate signed by 3rd party vendor like Verisign, GoDaddy, etc. This is best solution as this cert will be trusted by all the browsers irrespective of the device. 2. Use a PAN self signed certificate or domain generated sub-ordinate certificate. Install its certificate authority on the client browsers. Though technically this will work, practically it is very difficult to implement this since typically you wouldn't be knowing which device the user will be using. So not scalable. Hope it helps. Regards, Dileep
