Use the attached project for generating a pkcs#10 certificate signing request, to be submitted to an external Certification Authority.
The CA will issue a certificate that, together with the private key priv.pvk also created by the CSRCreator project, and any intermediate CA certificates from the CA, can be assembled into a pkcs#12 PFX file, using the PFXAssembler demo project, which is already included in ST 4.0.
