Kerberos

[BadWood17]

Good day, everyone!

I work with Kerberos authentication using wireshark to capture packets with information in it.
I want to hashcat Kerberos hashes, but have some problems with the template.

For example
 
Kerberos 5 AS-REQ Pre-Auth etype 23     
$krb5pa$23$user$realm$salt$4e751db65422b2117f7eac7b721932dc8aa0d9966785ecd958f971f622bf5c42dc0c70b532363138363631363132333238383835

This is an example from hashcat website.

The first question: $krb5pa - so in my wireshark traffick the field will be different? or i should leave it in that way?

The second question: $23 - what is this? should i find in packets another value? Look at the attachment, i have maybe different value? should i put 18 in the template?

To take the information for the template i have to look it up in this packets.

Which of the packet should i take?

Well, i try to find the answer, looking in one of them.
Look please at the attachment and answer the questions.

I want to make my own project using c++. Could u please tell me answers without JtR?

Thanks a lot!)

Please, tell me. Is it possible to take all required fields from 1 packet, or this information should be taken from many?
