Encrypt MIME using a digital certificate to create PKCS7 encrypted S/MIME. Chilkat2 Java

        // See Global Unlock Sample for sample code.

        // A digital certificate is required to create PKCS7 encrypted MIME.
        // It can come from a variety of sources: .cer file, .pfx file, PEM files,
        // an in-memory representation, or directly from a Windows
        // registry-based certificate store.

        // This example will load a certificate object from a .cer file.
        // Note: Only the public-key is required to encrypt.  (Decryption
        // requires a private key.)
