I decided to switch to pcapng, because it has many advantages. New attack modes requiere to calculate pre-hashes and nonces during runtime of the dumper. pcapng format is able to handle comments, and we can store this values within the comment field, to provide the following conversiontool with this values. I don't like the idea to use separate files or incredibly long commandlines for this purpose.
You can download first hcxdumptool testversion here:
https://github.com/ZerBea/hcxdumptool_bleeding_testing
This is a bleeding version. So expect compiler warnings and missing functions as well as some (heavy) bugs!
Latest update hcxpcaptool is able to evaluate pcapng options:
$ hcxpcaptool -o test.hccapx sae_simple_psk.pcapng
start reading from sae_simple_psk.pcapng

hcxdumptool will save the interface name and the first three bytes of the capture device mac (OUI), too, to identify faulty vendor drivers. Also pre-hashed data like client based calculated authenticationkeys and nonces are saved in the comment fields.
