Types ¶
type Verifier ¶
type Verifier struct {
// contains filtered or unexported fields
}
Verifier verifies that a given postback data matches its signature
func NewLegacyVerifier ¶
func NewLegacyVerifier() *Verifier
NewLegacyVerifier can be used for postbacks versions 1.0 and 2.0. Google's certificate-transparency-go does not work with ApplePublicKeyLegacy but we can create it manually.
func NewVerifier ¶
func NewVerifier() *Verifier
NewVerifier is used to create an instance of Verifier for postback versions 2.1 and later.
func (*Verifier) VerifySignature ¶
VerifySignature verifies a given postback data and signature The parameter data is expected to be a byte array. If string array is given, the function will use the correct delimiter to create the byte array needed to verify the signature against.
