Types ¶
type LogRootVerifier ¶
type LogRootVerifier interface {
// VerifyRoot checks the signature of newRoot and the consistency proof if trusted.TreeSize != 0.
VerifyRoot(trusted *types.LogRootV1, newRoot *tpb.SignedLogRoot, proof [][]byte) (*types.LogRootV1, error)
}
LogRootVerifier verifies a Trillian Log Root.
type LogTracker ¶
type LogTracker struct {
// contains filtered or unexported fields
}
LogTracker tracks a series of consistent log roots.
func NewFromSaved ¶
func NewFromSaved(lv LogRootVerifier, lr types.LogRootV1) *LogTracker
NewFromSaved creates a log tracker from a previously saved trusted root.
func NewSynchronous ¶
func NewSynchronous(lv LogRootVerifier) *LogTracker
NewSynchronous creates a log tracker from no trusted root.
func (*LogTracker) LastVerifiedLogRoot ¶
func (l *LogTracker) LastVerifiedLogRoot() *pb.LogRootRequest
LastVerifiedLogRoot retrieves the tree size of the latest log root.
func (*LogTracker) SetUpdatePredicate ¶
func (l *LogTracker) SetUpdatePredicate(f UpdateTrustedPredicate)
SetUpdatePredicate allows relying parties to have finer grained control over when the trusted root is updated. It is legal to set the predicate at any time, but it makes the most sense to do so before any other calls.
func (*LogTracker) VerifyLogRoot ¶
func (l *LogTracker) VerifyLogRoot(state *pb.LogRootRequest, root *pb.LogRoot) (*types.LogRootV1, error)
VerifyLogRoot verifies root and updates the trusted root if it is newer. state must be equal to the most recent value from LastVerifiedLogRoot(). If two clients race to VerifyLogRoot at the same time, if one of them updates the root, the other will fail.
type UpdateTrustedPredicate ¶
UpdateTrustedPredicate returns a bool indicating whether the local reference for the latest SignedLogRoot should be updated.
