Saves the current Keyring to disk.
This method saves the current keyring to disk. There are two output options. The keyring may either be saved to a single key file or may be saved to a directory.
To save the keyring to a directory set KeyringPath to the path. The directory must already exist. The class will create a "pubring.gpg" and "secring.gpg" file in the specified directory. If the files already exist they will be overwritten.
To save the keyring to a key file set KeyringPath to a path and file name. If the file already exists it will be overwritten.
