resending it here.

Hello mailing list,

I set up ESP deciphering/decoding preferences with following relevant
parameters in wireshark 4.4.6:

 -- attempt to check ESP Authentication -- off
 -- attempt to detect/decode NULL encrypted ESP payload -- off

then I entered ESP SAs with relevant IPs, SPIs and deciphering key, leaving
the authentication algorithm at NULL and wireshark did not decipher ESP
payload.
I set authentication algorithm to HMAC-SHA1-96 (RFC 2404) then, without
authentication key and wireshark did decipher as expected.

Question: why wireshark cares so much about authentication algorithm in
this scenario, shouldn't it just decipher with all the information for it
available or what goes on here as in "potential bug" ?

Kind Regards

Ariel Burbaickij
