Configure PDA for SSL
In Windows Mobile-based PDA's you also need to add the CA Certificate to the Trusted Root
Certificates store if you don't have a certificate of one of the Certified Authorities describe in the first
chapter.
The certificates should be in DER format to install it on the PDA. By default the generated SSL
certificates on Linux are in PEM format. The DER certificate is a base64 encoded PEM certificate.
You can convert the certificate type by the following commands:Code: Select all
openssl x509 -in ca.crt -inform PEM -out ca.cer -outform DER
openssl x509 -in host.crt -inform PEM -out host.cer -outform DER
After converting both certificates you need to copy them to the PDA.
By selecting the certificates on your PDA they will be stored in the Trusted Root Certificates store of
your PDA.
In my case only the second (host.crt) key was required to get it work.
