Functions

func AnyOverlap

func AnyOverlap(x, y []byte) bool

AnyOverlap reports whether x and y share memory at any (not necessarily corresponding) index. The memory beyond the slice length is ignored.

func Bn2Bytes

func Bn2Bytes(bn *big.Int, bnLen int) []byte

func ComputeSessionKey

func ComputeSessionKey(clientPrivKey *DhKey, serverPubKey []byte) []byte

func InexactOverlap

func InexactOverlap(x, y []byte) bool

InexactOverlap reports whether x and y share memory at any non-corresponding index. The memory beyond the slice length is ignored. Note that x and y can have different lengths and still not have any inexact overlap.

InexactOverlap can be used to implement the requirements of the crypto/cipher AEAD, Block, BlockMode and Stream interfaces.

func NewECBDecrypter

func NewECBDecrypter(b cipher.Block) cipher.BlockMode

func NewECBEncrypter

func NewECBEncrypter(b cipher.Block) cipher.BlockMode

func NewTLSFromTCP

func NewTLSFromTCP(conn *net.TCPConn, sslCertPath string, sslKeyPath string, user string) (*tls.Conn, error)
