Delphi - Load PFX Certificates without installing it on Windows using CAPICOM

Question

I'm using CAPICOM to load a certificate needed by a WebService client.

I need to have the certificate installed in Windows, and then open it from the certificate file itself, which I think is "kinda stupid".

Is there any way to either (in order of preference):

• Save the PFX File contents to a memo field in the database, and load it from there, without installing it on Windows?

• Load the PFX File from the file itself, without installing it on Windows

I'm using Delphi XE3, LibEay32 and Capicom 2.0

Answer 1

If you want to install the certificate in Windows you will ALWAYS get a popup asking the user for permission, unless the certificate comes from a root that is already trusted. If you don't want that the only option is to use the PFX contents from a memo field each time you need the certificate.

I have no experience with Capicom, but from what I read it is a Microsoft DLL that you use?

If you are having problems with Capicom and LibEay32 you might want to check out the Eldos Secure BlackBox components. I have very good experiences with those and their support is great.
