hcxtools - solution for capturing wlan traffic and conversion to hashcat formats

==========
hcxdumptool: added option to save GPS information to pcapng dumpfile
--nmea_pcapng                  : write GPS information to pcapng dump file

There are standard and non-standard (e.g. Kismet GPS data) message formats. Nearly all GPS receivers output NMEA data. The NMEA standard is formatted in lines of data called sentences. Each sentence contains various bits of data organized in comma delimited format (i.e. data separated by commas).

NME0183 GPRMC, GPGGA and GPWPL sentences are directly stored to a PCPNG CUSTOM BLOCK:

hcxpcapngtool detect the presence of NMEA 0183 (recorded by hcxdumptool) and store it either as NMEA 0183 or as CSV (both formats are very common and widely used):

Code:

--nmea=<file>                      : output GPS data in NMEA 0183 format
                                     format: NMEA 0183 $GPGGA, $GPRMC, $GPWPL
                                     to convert it to gpx, use GPSBabel:
                                     gpsbabel -i nmea -f hcxdumptool.nmea -o gpx,gpxver=1.1 -F hcxdumptool.gpx
                                     to display the track, open file.gpx with viking
--csv=<file>                       : output ACCESS POINT information in CSV format
                                     delimiter: tabulator (0x08)
                                     columns:
                                     YYYY-MM-DD HH:MM:SS MAC_AP ESSID ENC_TYPE CIPHER AKM COUNTRY_INFO CHANNEL RSSI GPS(DM.m) GPS(D.d) GPSFIX SATCOUNT HDOP ALTITUDE UNIT
                                     to convert it to other formats, use bash tools or scripting languages
                                     GPS FIX:
                                     0 = fix not available or invalid
                                     1 = fix valid (GPS SPS mode)
                                     2 = fix valid (differential GPS SPS Mode)
                                     3 = not supported
                                     4 = not supported
                                     5 = not supported
                                     6 = fix valid (Dead Reckoning Mode)

There is no plan to add an additional format, because the entire information is available in NMEA 0183 fields or CSV fields.
Conversion to whatever you want can be done by simple bash commands or tools like
gpsbabel
https://www.gpsbabel.org/
or online converters

Viking will show this e.g. by GPS babel converted data on a map:
