"sekurlsa::tickets /export" seems to corrupt (at least) one byte in resulting ccache file #414

I compared two ticket dumps, one with Rubeus (Rubeus.exe monitor /interval:1 /filteruser:DC01$), one with mimikatz (sekurlsa::minidump lsass.DMP sekurlsa::tickets /export). The resulting ccache file (impacket-ticketConverter) is almost identical, but - in my example - one byte is corrupt and prevents proper usage with, e.g., export KRB5CCNAME=

xxd dc01.ccache.rubeus rubeus.hex
xxd dc01.ccache.mimikatz mimikatz.hex

diff rubeus.hex mimikatz.hex

May also be the "fault" of impacket-ticketConverter - however it works with Rubeus...
