func VerifySignature

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

VerifySignature verifies an Ed25519 signature.

func VerifySignatureJSON

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.
