类型
type SHA3
type SHA3 struct {
// contains filtered or unexported fields
}
SHA3 is an instance of a SHA-3 hash. It implements hash.Hash.
func New224
func New224() *SHA3
New224 creates a new SHA3-224 hash.
func New256
func New256() *SHA3
New256 creates a new SHA3-256 hash.
func New384
func New384() *SHA3
New384 creates a new SHA3-384 hash.
func New512
func New512() *SHA3
New512 creates a new SHA3-512 hash.
(*SHA3) AppendBinary
func (s *SHA3) AppendBinary(p []byte) ([]byte, error)
AppendBinary implements encoding.BinaryAppender.
(*SHA3) BlockSize
func (s *SHA3) BlockSize() int
BlockSize returns the hash’s rate.
(*SHA3) MarshalBinary
func (s *SHA3) MarshalBinary() ([]byte, error)
MarshalBinary implements encoding.BinaryMarshaler.
(*SHA3) Reset
func (s *SHA3) Reset()
Reset resets the hash to its initial state.
(*SHA3) Size
func (s *SHA3) Size() int
Size returns the number of bytes Sum will produce.
(*SHA3) Sum
func (s *SHA3) Sum(b []byte) []byte
Sum appends the current hash to b and returns the resulting slice.
(*SHA3) UnmarshalBinary
func (s *SHA3) UnmarshalBinary(data []byte) error
UnmarshalBinary implements encoding.BinaryUnmarshaler.
(*SHA3) Write
func (s *SHA3) Write(p []byte) (n int, err error)
Write absorbs more data into the hash’s state.
type SHAKE
type SHAKE struct {
// contains filtered or unexported fields
}
SHAKE is an instance of a SHAKE extendable output function.
func NewCSHAKE128
func NewCSHAKE128(N, S []byte) *SHAKE
NewCSHAKE128 creates a new cSHAKE128 XOF.
N is used to define functions based on cSHAKE, it can be empty when plain cSHAKE is desired. S is a customization byte string used for domain separation. When N and S are both empty, this is equivalent to NewSHAKE128.
func NewCSHAKE256
func NewCSHAKE256(N, S []byte) *SHAKE
NewCSHAKE256 creates a new cSHAKE256 XOF.
N is used to define functions based on cSHAKE, it can be empty when plain cSHAKE is desired. S is a customization byte string used for domain separation. When N and S are both empty, this is equivalent to NewSHAKE256.
func NewSHAKE128
func NewSHAKE128() *SHAKE
NewSHAKE128 creates a new SHAKE128 XOF.
func NewSHAKE256
func NewSHAKE256() *SHAKE
NewSHAKE256 creates a new SHAKE256 XOF.
(*SHAKE) AppendBinary
func (s *SHAKE) AppendBinary(p []byte) ([]byte, error)
AppendBinary implements encoding.BinaryAppender.
(*SHAKE) BlockSize
func (s *SHAKE) BlockSize() int
BlockSize returns the rate of the XOF.
(*SHAKE) MarshalBinary
func (s *SHAKE) MarshalBinary() ([]byte, error)
MarshalBinary implements encoding.BinaryMarshaler.
(*SHAKE) Read
func (s *SHAKE) Read(p []byte) (n int, err error)
Read squeezes more output from the XOF.
Any call to Write after a call to Read will panic.
(*SHAKE) Reset
func (s *SHAKE) Reset()
Reset resets the XOF to its initial state.
(*SHAKE) UnmarshalBinary
func (s *SHAKE) UnmarshalBinary(data []byte) error
UnmarshalBinary implements encoding.BinaryUnmarshaler.
(*SHAKE) Write
func (s *SHAKE) Write(p []byte) (n int, err error)
Write absorbs more data into the XOF’s state.
It panics if any output has already been read.
