I need to be able to install a .p12 client side certificate to be sent to the admin section of my company's site to authenticate me as an employee. In FireFox for PC there is the ability to install this client certificate. In the mobile I cannot figure out how to get this to work. I just bought an Asus Transformer Android Tablet running Honeycomb. I have tried the following method below: http://support.mozilla.com/en-US/questions/786035 I get to the screen where I am able to present and choose a certificate but I still get the (Error code: ssl_error_handshake_failure_alert). Now that Android is really picking up steam, there needs to be a way to install client side certificates to present to sites requesting them. Is there another way to hack the system to allow or install a client side certificate in .p12 format?
