Functions ¶

func NewDos2UnixHash ¶

func NewDos2UnixHash(h hash.Hash) hash.Hash

NewDos2UnixHash returns a hash.Hash that wraps a hash.Hash while replacing '\r\n' with '\n' in the input. NOTE: calling Sum() will write '\r' if it was the last character seen. If an '\n' is written after the call to Sum() the output will be incorrect. Recommended to not write after Sum() is called.

Types ¶

type Hash ¶

type Hash struct {
	// contains filtered or unexported fields
}

Hash is a generic hash built from a hash.Hash and path transform function

func New ¶

func New(hasher func() hash.Hash) *Hash

New returns a Hash object given a hash.Hash generator and path transform function

func (*Hash) IsValidKey ¶

func (h *Hash) IsValidKey(key string) bool

IsValidKey return true if 'key' is a valid key to the hash

func (*Hash) New ¶

func (h *Hash) New() hash.Hash

New returns a new instance of the underlying hash.Hash

func (*Hash) Sum ¶

func (h *Hash) Sum(data []byte) (string, error)

Sum accepts a []byte of data and returns the sum

type Hasher ¶

type Hasher interface {
	IsValidKey(string) bool
	New() hash.Hash
	Sum([]byte) (string, error)
}

Hasher is an interface representing both the hash function (returned by New()) and methods to verify hash keys and transform them before accessing the backend storage.
