Functions ¶
func ChannelHash ¶
GenerateHash returns the hash for a given channel by XORing the channel name and PSK.
func CreateNonce ¶
CreateNonce creates a 128-bit nonce. It takes a uint32 packetId, converts it to a uint64, and a uint32 fromNode. The nonce is concatenated as [64-bit packetId][32-bit fromNode][32-bit block counter].
func GenerateByteSlices ¶
func GenerateByteSlices() [][]byte
GenerateByteSlices creates a bunch of weak keys for use when interfacing on MQTT. This creates 128, 192, and 256 bit AES keys with only a single byte specified
func ParseKey ¶
ParseKey converts the most common representation of a channel encryption key (URL encoded base64) to a byte slice
Types ¶
type Something ¶
type Something struct {
// contains filtered or unexported fields
}
Something is something created to track keys for packet decrypting
type Transport ¶
type Transport interface {
Connect() error
SendPacket(data []byte) error
RequestConfig() error
// Listen(ch chan)
Close() error
}
Transport defines methods required for communicating with a radio via serial, ble, or tcp Probably need to reevaluate this to just use the ToRadio and FromRadio protobufs
