/**
	 * Creates a pcks7 file from the certificate and key files.
	 * @param certFile The X509 DER encoded certificate file.
	 * @param keyFile The PCKS8 DER encoded private key file.
	 * @param password Option password for the private key file.  This is required if the private key file is encrypted.  Should be null or empty
	 * if the private key file is not encrypted.
	 * @param createFile Optional file descriptor for the output file of the pkcs12 file.  If this is null, the file name is based on the 
	 * certificate file name.
	 * @return File descriptor of the created pcks7 file.  Null if an error occurred.
