From the developer: "Chilkat Certificate is an ActiveX control that makes it easy for your applications to get information about the security certificates that are stored on your computer. Locate and examine certificates in file or registry-based stores. Move certificates from one store to another. Import the following types of certificates into certificate stores: DER encoded binary X.509 (.CER), Base-64 encoded X.509 (.CER), Cryptographic Message Syntax Standard - PKCS #7 Certificates (.P7B), PEM format. Also hooks in with other Chilkat components such as Mail, S/MIME, and Crypt."
