Functions ¶

func New ¶

func New() hash.Hash

New returns a new hash.Hash that calculates the Tiger/192 hash digest.

Types ¶

type Hash ¶

type Hash [Size]byte

Hash is a tiger hash value.

func HashBytes ¶

func HashBytes(b []byte) (out Hash)

HashBytes calculates the tiger hash of a byte slice.

func MustParseBase32 ¶

func MustParseBase32(s string) (out Hash)

MustParseBase32 parses the tiger hash from base32 encoding and panics on error.

func TreeHash ¶

func TreeHash(r io.Reader) (root Hash, err error)

TreeHash calculates a Tiger Tree Hash of a reader.

func (Hash) Base32 ¶

func (h Hash) Base32() string

Base32 returns base32 representation of the hash.

func (Hash) Bytes ¶

func (h Hash) Bytes() []byte

Bytes returns byte slice from the hash. Same as h[:].

func (*Hash) FromBase32 ¶

func (h *Hash) FromBase32(s string) error

FromBase32 parses hash from base32 encoding.

func (Hash) Hex ¶

func (h Hash) Hex() string

Hex returns hexadecimal representation of the hash.

func (Hash) IsZero ¶

func (h Hash) IsZero() bool

IsZero check if hash value is zero.

func (Hash) MarshalADC ¶ added in v0.9.0

func (h Hash) MarshalADC(buf *bytes.Buffer) error

MarshalADC implements adc.Marshaler.

func (Hash) MarshalBase32 ¶ added in v0.6.2

func (h Hash) MarshalBase32(buf []byte) error

MarshalBase32 encodes the hash to a given buffer. Buffer should be at least Base32Len.

func (Hash) MarshalText ¶

func (h Hash) MarshalText() ([]byte, error)

MarshalText implements encoding.TextMarshaler.

func (Hash) String ¶

func (h Hash) String() string

String returns base32 representation of the hash.

func (*Hash) UnmarshalADC ¶ added in v0.9.0

func (h *Hash) UnmarshalADC(buf []byte) error

UnmarshalADC implements adc.Unmarshaler.

func (*Hash) UnmarshalBase32 ¶ added in v0.6.2

func (h *Hash) UnmarshalBase32(buf []byte) error

UnmarshalBase32 decodes the hash from a given buffer.

func (*Hash) UnmarshalText ¶

func (h *Hash) UnmarshalText(text []byte) error

UnmarshalText implements encoding.TextUnmarshaler.

type Leaves ¶ added in v0.3.2

type Leaves []Hash

Leaves are a sequence of concatenated hashes that can be used to validate the single parts of a certain file.

func TreeLeaves ¶ added in v0.3.2

func TreeLeaves(r io.Reader) (lvl Leaves, err error)

TreeLeaves computes the TTH leaves of a reader.

func (Leaves) TreeHash ¶ added in v0.4.0

func (in Leaves) TreeHash() Hash

TreeHash converts leaves into a hash.
