Functions

func CreateSessionId 

func CreateSessionId() string

CreateSessionId creates & returns unique session ID string

func EncodeMsMppeKey 

func EncodeMsMppeKey(salt, key, authenticatorKey, sharedSecret []byte) []byte

EncodeMsMppeKey implements RFC 2048 encoding for MS-MPPE-Send-Key & MS-MPPE-Recv-Key radius keys, returns padded & encoded key. See: https://www.ietf.org/rfc/rfc2548.txt 2.4.2, 2.4.3

func NewAttribute 

func NewAttribute(typ AttrType, data []byte) attribute

NewAttribute creates and returns new attribute of given type (typ) & value the new attribute is padded with zeros to 4 byte boundary

func NewAttributeScanner 

func NewAttributeScanner(eapData Packet) (*attributeScanner, error)

func NewDuplicateDetector 

func NewDuplicateDetector(bitLen uint) *duplicateDetector

NewDuplicateDetector returns a new detector supporting bitLen possible combinations

func NewRawAttribute 

func NewRawAttribute(data []byte) attribute

NewRawAttribute 'casts' given slice to Attribute type without any validations

func XorBytes 

func XorBytes(a, b []byte) []byte

XorBytes returns a new byte slice c where c[i] = a[i] ^ b[i]

Types

type AttrType 

type AttrType uint8

type Attribute 

type Attribute interface {
	Type() AttrType
	Value() []byte
	String() string
	Len() int
	AttrLen() uint8
	Marshaled() []byte
}

attribute EAP Method's attribute implementation attribute provides the following interface:

type Packet 

type Packet []byte

Packet represents EAP Packet

func NewPacket 

func NewPacket(code, identifier uint8, data []byte, additionalCapacity ...uint) Packet

NewPacket creates an EAP Packet with initialized header and appends provided data if additionalCapacity is specified, NewPacket reserves extra additionalCapacity bytes capacity in the returned packet byte slice

func NewPreallocatedPacket 

func NewPreallocatedPacket(identifier uint8, data []byte) (Packet, error)

NewPreallocatedPacket creates an EAP Packet from/in passed data slice & initializes its header

func (Packet) Append 

func (eap Packet) Append(a Attribute) (Packet, error)

Append adds given Attribute to EAP Packet and amends the packet's header to reflect the new EAP packet size

func (Packet) Code 

func (p Packet) Code() uint8

Code returns EAP Packet Message Code

func (Packet) Failure 

func (p Packet) Failure() Packet

Failure returns RFC 3748, 4.2 Failure packet with Identifier set from p

func (Packet) Identifier 

func (p Packet) Identifier() uint8

Identifier returns EAP Message Identifier

func (Packet) IsSuccess 

func (p Packet) IsSuccess() bool

IsSuccess returns if the EAP Packet Code is Success (3)

func (Packet) Len 

func (p Packet) Len() int

Len returns EAP Packet length derived from its header (vs. len of []byte)

func (Packet) Truncate 

func (p Packet) Truncate() Packet

Truncate truncates EAP Packet to its header defined length

func (Packet) Type 

func (p Packet) Type() uint8

Type returns EAP Method Type or 0 - reserved if not available

func (Packet) TypeData 

func (p Packet) TypeData() []byte

TypeData returns EAP Packet Type data part

func (Packet) TypeDataUnsafe 

func (p Packet) TypeDataUnsafe() []byte

TypeDataUnsafe - same as TypeData, but doesn't check the packet length

func (Packet) Validate 

func (p Packet) Validate() error

Validate verifies that the packet is not nil & it's length is correct
