Types

type ECDSASignature

type ECDSASignature struct {
	R, S *big.Int
}

Represents the two mathematical components of an ECDSA signature once decomposed.

type Envelope

type Envelope struct {
	RawMessage json.RawMessage `json:"message"`
	Message    interface{}     `json:"-"`
	Signature  string          `json:"signature"`
}

Encapsulates the overall message we're trying to decode and validate.

func NewEnvelopeFromJSON

func NewEnvelopeFromJSON(s string) (*Envelope, error)

Attempts to create a new envelope structure from the given JSON string.

func (*Envelope) Validate

func (e *Envelope) Validate(publicKey *ecdsa.PublicKey) error

The central validation routine that validates this message against the given public key. On success, returns nil, on failure returns a relevant error.

type MessageBody

type MessageBody struct {
	Type        string          `json:"type"`
	UserID      uint32          `json:"userId"`
	Transaction json.RawMessage `json:"transaction"`
}

The body of the message to be contained in the Message field of our Envelope structure.
