Ok I'm only getting the CURLE_SSL_CERTPROBLEM when i use the crypto engine. When i don't
and i use my own key i get an exception thrown (5, access denied).

I have successfully used openssl to create my pem file, using switch:-

openssl pkcs12 -in henry.pfx -out henry.pem

This created me a pem file, with a rsa private key and a certificate inside it.

Took your advice here and am using the ca-bundle.crt file.

Set this to be the same as pCertFile. So "Henry.pem"

Set this to be "PEM"

I'm just trying to connect to any SSL server at the mo and trying to connect to
just as a test. When i browse to this site with IE it doesn't ask me to Ok any
certs so i presume that the ca-bundle will work in cURLs case.
