CE 4.1 and higher does support SSL Client certificates. For more information see this MSDN page.
Another option is to use OpenSSL, which is a GPL library from OpenSSL.org. ADS doesn't provide support for OpenSSL, but as a convenience to our customers, we have gone through the process of building the CE DLLs (version 0.9.7c) for the ARM architecture as documented in the OpenSSL readmes. modified Oct 16, 03 (ctacke): added header files to zip
We are using AGX with WinCE v4.20.8 and VB.NET. How can we add/renew the SSL root certificate? For example, the GTE Cyber Trust Root certificate is going to expire on 2/23/2006. If we want to put a new one on the system, what shall we do to let the system recognise it? Please kindly advise.
