- * and additional messages (unsigned or signed).

+ * instead to ensure you are only reading signed data.
+ *
+ * The method does not return, but has some noteable exit-codes:
+ * 111 signals an internal error like the inability to execute gpgv,
+ * 112 indicates a clear-signed file which doesn't include a message,
+ * which can happen if APT is run while on a network requiring
+ * authentication before usage (e.g. in hotels)
+ * All other exit-codes are passed-through from gpgv.
*
