Types

type Instance

type Instance struct {
	crypto.Hash
	Digest string
}

Instance consists of the hash type and an internal digest value

func (*Instance) Calculate

func (d *Instance) Calculate(b []byte) string

Calculate but do not update the internal digest value for b. Subsequent calls to MarshalText, String, etc will not use the returned value.

func (*Instance) MarshalText

func (d *Instance) MarshalText() (text []byte, err error)

MarshalText returns the marshalled digest in HTTP Digest header format

func (*Instance) String

func (d *Instance) String() string

Return a string representation digest in HTTP Digest header format

func (*Instance) UnmarshalText

func (d *Instance) UnmarshalText(text []byte) (err error)

UnmarshalText parses the digest from HTTP Digest header format

func (*Instance) Update

func (d *Instance) Update(b []byte)

Update (after calculating) the internal digest value for b. Subsequent calls to MarshalText, String, etc will use the updated value.

func (*Instance) Verify

func (d *Instance) Verify(b []byte) bool

Verify by calculating the digest value for b and checking against the internal digest value. Returns true if the digest values match.
