Functions ¶
func RegisterHash ¶
func RegisterHash(h Hash, f func() ResumableHash)
RegisterHash registers a function that returns a new instance of the given hash function. This is intended to be called from the init function in packages that implement hash functions.
Types ¶
type Hash ¶
type Hash uint
Hash identifies a cryptographic hash function that is implemented in another package.
func (Hash) Available ¶
Available reports whether the given hash function is linked into the binary.
func (Hash) HashFunc ¶
HashFunc simply returns the value of h so that Hash implements SignerOpts.
func (Hash) New ¶
func (h Hash) New() ResumableHash
New returns a new ResumableHash calculating the given hash function. New panics if the hash function is not linked into the binary.
type ResumableHash ¶
type ResumableHash interface {
// ResumableHash is a superset of hash.Hash
hash.Hash
// Len returns the number of bytes written to the Hash so far.
Len() uint64
// State returns a snapshot of the state of the Hash.
State() ([]byte, error)
// Restore resets the Hash to the given state.
Restore(state []byte) error
}
ResumableHash is the common interface implemented by all resumable hash functions.
