const Size = sha256.Size

Size is the number of bytes in a hash.

This section is empty.

func BytesString(hash []byte) string

BytesString returns a string representation of the hash that is represented in bytes.

type Hash [Size]byte // SHA-256 hash always 32 bytes

Hash represents a SHA-256 hash code. It is always 32 bytes long. Its representation is an array so it can be treated as a value.

var ZeroHash Hash

ZeroHash is the zero-valued hash.

func Of(data []byte) (hash Hash)

Of returns the SHA-256 hash of the data, as a Hash. The odd name works well in the client: sha256key.Of.

func Parse(str string) (hash Hash, err error)

Parse returns the hash whose standard format (possibly absent the brackets) is the value of str.

func (hash Hash) EqualString(b string) bool

EqualString compares the byte-level representation of a hash with its hex string representation, avoiding allocation.

func (hash Hash) String() string

String returns a hexadecimal representation of the hash.
