Types

type Entry

type Entry struct {
	Principal Principal
	Timestamp time.Time
	KVNO8     uint8
	Key       types.EncryptionKey
	KVNO      uint32
}

Keytab Entry struct.

func (*Entry) Bytes

func (entry *Entry) Bytes() []byte

func (*Entry) KeyVersionNumber

func (entry *Entry) KeyVersionNumber() int

The 32-bit key version overrides the 8-bit key version.

type Keytab

type Keytab struct {
	Version uint16
	Entries []Entry
}

Keytab struct.

func Load

func Load(ktPath string) (kt Keytab, err error)

Load a Keytab file into a Keytab type.

func NewKeytab

func NewKeytab() Keytab

NewKeytab creates new, empty Keytab type.

func Parse

func Parse(b []byte) (kt Keytab, err error)

Parse byte slice of Keytab data into Keytab type.

func (*Keytab) Bytes

func (kt *Keytab) Bytes() []byte

func (*Keytab) GetEncryptionKey

func (kt *Keytab) GetEncryptionKey(nameString []string, realm string, kvno, etype int) (types.EncryptionKey, error)

GetEncryptionKey returns the EncryptionKey from the Keytab for the newest entry with the required kvno, etype and matching principal.

type Principal

type Principal struct {
	NumComponents int16
	Realm         string
	Components    []string
	NameType      int32
}

Keytab entry principal struct.

func (*Principal) Bytes

func (principal *Principal) Bytes() []byte

func (*Principal) Name

func (principal *Principal) Name() string
