Functions

func NewConn

func NewConn(connection net.Conn, aead aeadCipher, saltFilter SaltFilter) net.Conn

NewConn wraps a stream net.Conn connection with a cipher.

func NewPacketConn

func NewPacketConn(connection net.PacketConn, aead aeadCipher, saltFilter SaltFilter) net.PacketConn

NewPacketConn wraps a net.PacketConn with a cipher.

Types

type AEADCipherAdapter

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

func AESGCM

func AESGCM(preSharedKey []byte) *AEADCipherAdapter

AESGCM creates a new Cipher with a pre-shared key of 16 or 32 bytes.

func Chacha20Poly1305

func Chacha20Poly1305(preSharedKey []byte) *AEADCipherAdapter

Chacha20Poly1305 creates a new Cipher with a pre-shared key of 32 bytes.

func (*AEADCipherAdapter) Crypt

func (c *AEADCipherAdapter) Crypt(salt []byte) (cipher.AEAD, error)

func (*AEADCipherAdapter) GetSaltSize

func (c *AEADCipherAdapter) GetSaltSize() int

type SaltFilter

type SaltFilter interface {
	AddSalt(b []byte)
	IsSaltRepeated(b []byte) bool
}

SaltFilter is used to mitigate replay attacks by detecting repeated salts.
