Functions

func CreateFingerprint

func CreateFingerprint(version uint32, localStableIdentifier []byte, localIdentityKeys []axolotl.ECPublicKey, remoteStableIdentifier []byte, remoteIdentityKeys []axolotl.ECPublicKey) ([]string, []byte, error)

https://github.com/signalapp/libsignal-protocol-java/blob/fde96d22004f32a391554e4991e4e1f0a14c2d50/java/src/main/java/org/whispersystems/libsignal/fingerprint/NumericFingerprintGenerator.java#L85 returns: the fingerprint in blocks of five digits

func CreateFingerprintNumbers

func CreateFingerprintNumbers(localFingerprint []byte, remoteFingerprint []byte) []string

func CreateFingerprintSimple

func CreateFingerprintSimple(version uint32, local string, localKey []byte, remote string, remoteKey []byte) ([]string, []byte, error)

I'm not particular happy with the name "CreateFingerprintSimple"

func CreateQRFingerprint

func CreateQRFingerprint(version uint32, localFingerprint []byte, remoteFingerprint []byte) ([]byte, error)
