Types

type Envelope

type Envelope struct {
	Version byte   // current version
	Dsa     string // digital signature algorithm
	Cipher  string // symmetric-key algorithm
	Payload []byte // symmetric encryped content
	Mac     []byte // mac to verify decrypted plain content
	Key     []byte // public key encryped symmetric-key
	Iv      []byte // iv of cipher
	Sig     []byte // signature signed by sender with field above
}

func DecodeFromRLPBytes

func DecodeFromRLPBytes(raw []byte) (*Envelope, error)

DecodeFromRLPBytes unmarshal raw to an Envelope

func NewEnvelope

func NewEnvelope(content, pub []byte, dsa, cipher string) (e *Envelope, err error)

NewEnvelope create an envelope, with content and public key of receiver

func (*Envelope) Decrypt

func (e *Envelope) Decrypt(prv []byte) ([]byte, error)

Decrypt decrypt envelope with your private key

func (*Envelope) EncodeToRLPBytes

func (e *Envelope) EncodeToRLPBytes(prv *ecdsa.PrivateKey) ([]byte, error)

EncodeToRLPBytes marshal an Envelope to raw with signature
