Types

type Cipher

type Cipher struct {
	// contains filtered or unexported fields
}

A Cipher is an instance of Blowfish encryption using a particular key.

type KeySizeError

type KeySizeError int

func (KeySizeError) Error

func (k KeySizeError) Error() string

type PCCrypt

type PCCrypt struct {
	// contains filtered or unexported fields
}

type PCKeySizeError

type PCKeySizeError int

func (PCKeySizeError) Error

func (k PCKeySizeError) Error() string

type PSOCrypt

type PSOCrypt struct {
	Vector []uint8
	// contains filtered or unexported fields
}

PSOCrypt object to be used per-client for crypto.

func NewBBCrypt

func NewBBCrypt() *PSOCrypt

Returns a newly allocated PSOCrypt with randomly generated, appropriately sized keys for encrypting packets over PSOBB connections.

func NewPCCrypt

func NewPCCrypt() *PSOCrypt

Returns a newly allocated PSOCrypt with randomly generated, appropriately sized keys for encrypting packets over PSOPC connections.

func (*PSOCrypt) Decrypt

func (crypt *PSOCrypt) Decrypt(data []byte, size uint32)

Decrypt a block of data in place.

func (*PSOCrypt) Encrypt

func (crypt *PSOCrypt) Encrypt(data []byte, size uint32)

Encrypt a block of data in place.
