Kerberos V5

Implements parts of:

Kerberos Network Authentication Service (V5): RFC4120
Kerberos Version 5 GSS-API: RFC1964, RFC4121
Kerberos Pre-Authentication: RFC6113 (FAST)

You will find more complete documentation for this layer over Kerberos

Kerberos AS-Req

参数:

upn -- the user principal name formatted as "DOMAINuser" or "user@DOMAIN"
ip -- the KDC ip
key -- (optional) pass the Key object
password -- (optional) otherwise, pass the user's password

返回:

returns a named tuple (asrep=<...>, sessionkey=<...>)

Example:

>>> # The KDC is on 192.168.122.17, we ask a TGT for user1
>>> krb_as_req("user1@DOMAIN.LOCAL", "192.168.122.17", password="Password1")

Equivalent:

>>> from scapy.libs.rfc3961 import Key, EncryptionType
>>> key = Key(EncryptionType.AES256, key=hex_bytes("6d0748c546f4e99205
...: e78f8da7681d4ec5520ae4815543720c2a647c1ae814c9"))
>>> krb_as_req("user1@DOMAIN.LOCAL", "192.168.122.17", key=key)
