Functions

func FormatCheckpoint

func FormatCheckpoint(c Checkpoint) string

func NewVerifierFromSigner

func NewVerifierFromSigner(skey string) (note.Verifier, error)

func RightEdge

func RightEdge(n int64) []int64

RightEdge returns the stored hash indexes of the right edge of a tree of size n. These are the same hashes that are combined into a tlog.TreeHash and allow producing record and tree proofs for any size bigger than n. See tlog.StoredHashIndex for the definition of stored hash indexes.

Types

type Checkpoint

type Checkpoint struct {
	Origin string
	tlog.Tree

	// Extension is empty or a sequence of non-empty lines,
	// each terminated by a newline character.
	Extension string
}

A Checkpoint is a tree head to be formatted according to c2sp.org/checkpoint.

A checkpoint looks like this:

example.com/origin
923748
nND/nri/U0xuHUrYSy0HtMeal2vzD9V4k/BO79C+QeI=

It can be followed by extra extension lines.

func ParseCheckpoint

func ParseCheckpoint(text string) (Checkpoint, error)

type CosignatureV1Signer

type CosignatureV1Signer struct {
	// contains filtered or unexported fields
}

func NewCosignatureV1Signer

func NewCosignatureV1Signer(name string, key crypto.Signer) (*CosignatureV1Signer, error)

NewCosignatureV1Signer constructs a new CosignatureV1Signer that produces timestamped cosignature/v1 signatures from an Ed25519 private key.

func (*CosignatureV1Signer) KeyHash

func (v *CosignatureV1Signer) KeyHash() uint32

func (*CosignatureV1Signer) Name

func (v *CosignatureV1Signer) Name() string

func (*CosignatureV1Signer) Sign

func (s *CosignatureV1Signer) Sign(msg []byte) ([]byte, error)

func (*CosignatureV1Signer) Verifier

func (s *CosignatureV1Signer) Verifier() note.Verifier

func (*CosignatureV1Signer) VerifierKey

func (v *CosignatureV1Signer) VerifierKey() string

func (*CosignatureV1Signer) Verify

func (v *CosignatureV1Signer) Verify(msg, sig []byte) bool
