Functions

func VerifySignature

func VerifySignature(message []byte, key id.Ed25519, signature []byte) (ok bool, err error)

VerifySignature verifies an Ed25519 signature.

func VerifySignatureJSON

func VerifySignatureJSON(obj any, userID id.UserID, keyName string, key id.Ed25519) (bool, error)

VerifySignatureJSON verifies the signature in the given JSON object "obj" as described in Appendix 3 of the Matrix Spec.

This function is a wrapper over [Utility.VerifySignatureJSON] that creates and destroys the [Utility] object transparently.

If the "obj" is not already a json.RawMessage, it will re-encoded as JSON for the verification, so "json" tags will be honored.

Types

type Signatures

type Signatures map[id.UserID]map[id.KeyID]string

Signatures represents a set of signatures for some data from multiple users and keys.

func NewSingleSignature

func NewSingleSignature(userID id.UserID, algorithm id.KeyAlgorithm, keyID string, signature string) Signatures

NewSingleSignature creates a new Signatures object with a single signature.
