Overview ▾

Package verifier is designed to verify the signatures produced by a witness.

type WitnessVerifier

WitnessVerifier consists of a CT signature verifier. 

type WitnessVerifier struct {
    SigVerifier *ct.SignatureVerifier
}

func NewWitnessVerifier 

func NewWitnessVerifier(pk crypto.PublicKey) (*WitnessVerifier, error)

NewWitnessVerifier creates a witness signature verifier from a public key.

func (WitnessVerifier) VerifySignature 

func (wv WitnessVerifier) VerifySignature(sth api.CosignedSTH) error

VerifySignature finds and verifies this witness' signature on a cosigned STH. This may mean that there are other witness signatures that remain unverified, so future implementations may want to take in multiple signature verifiers like in the Note package (https://pkg.go.dev/golang.org/x/mod/sumdb/note).
