The zpay32 package implements a basic scheme for the encoding of payment
requests between two lnd nodes within the Lightning Network. The zpay32
encoding scheme uses the
zbase32
scheme along with a checksum to encode a serialized payment request.
The payment request serialized by the package consist of: the destination's public key, the payment hash to use for the payment, and the value of payment to send.

Variables ¶
ErrCheckSumMismatch is returned byt he Decode function fi when decoding an encoded invoice, the checksum doesn't match indicating an error somewhere in the bitstream.
Functions ¶
func Encode ¶
func Encode(payReq *PaymentRequest) string
Encode encodes the passed payment request using zbase32 with an added 4-byte crc32 checksum. The resulting encoding is 77-bytes long and consists of 124 ASCII characters. TODO(roasbeef): add version byte?
Types ¶
type PaymentRequest ¶
type PaymentRequest struct {
// Destination is the public key of the node to be paid.
Destination *btcec.PublicKey
// PaymentHash is the has to use within the HTLC extended throughout
// the payment path to the destination.
PaymentHash [32]byte
// Amount is the amount to be sent to the destination expressed in
// satoshis.
Amount btcutil.Amount
}
PaymentRequest is a bare-bones invoice for a payment within the Lightning Network. With the details of the invoice, the sender has all the data necessary to send a payment to the recipient.
func Decode ¶
func Decode(payData string) (*PaymentRequest, error)
Decode attempts to decode the zbase32 encoded payment request. If the trailing checksum doesn't match, then an error is returned.
