They claim that JTR can decrypt TGT of kerberos V5, but where can I get the AS_REP hex string to be decrypted? Instead the hex string of ticket in AS_REP always changes and the code entered in JTR must be static, I think.
So, any idea how to decrypt AS_REP to get the ticket by performing offline dictionary attack ?
