    #
    #  - Signer certificates are used when loading data to check the digital
    #    signature. The signature associated with the serialized data needs
    #    to match with one of the signer certificates for loading to succeed.
    #
    #  - Recipient certificates are used when serializing data for encryption.
    #    Loading the data can only be done through serializers that have been
    #    initialized with a certificate that's in the recipient certificates if
    #    encryption is enabled.
