Orpheus

Orpheus is a wrapper for a modified version of Impacket's GetUserSPNs.py and kerberosv5.py which alters the KDC Options (Ticket Options) and the Encryption Type for Kerberoasting.

Side Note: Orpheus is named after the Greek god that was able to get past Cerberus (the three headed dog) to get into Hades.
