Functions ¶

func GenerateIdentityKeyPair ¶

func GenerateIdentityKeyPair() (*identity.KeyPair, error)

GenerateIdentityKeyPair generates an identity keypair used for signing. Clients should only do this once at install time.

func GenerateLastResortKey ¶

func GenerateLastResortKey(serializer record.PreKeySerializer) (*record.PreKey, error)

GenerateLastResortKey will generate the last resort PreKey. Clients should do this only once, at install time, and durably store it for the length of the install.

func GeneratePreKeys ¶

func GeneratePreKeys(start int, count int, serializer record.PreKeySerializer) ([]*record.PreKey, error)

GeneratePreKeys generates a list of PreKeys. Client shsould do this at install time, and subsequently any time the list of PreKeys stored on the server runs low.

PreKeys IDs are shorts, so they will eventually be repeated. Clients should store PreKeys in a circular buffer, so that they are repeated as infrequently as possible.

func GenerateRegistrationID ¶

func GenerateRegistrationID() uint32

GenerateRegistrationID generates a registration ID. Clients should only do this once, at install time.

func GenerateSenderKey ¶

func GenerateSenderKey() []byte

func GenerateSenderKeyID ¶

func GenerateSenderKeyID() uint32

func GenerateSenderSigningKey ¶

func GenerateSenderSigningKey() (*ecc.ECKeyPair, error)

func GenerateSignedPreKey ¶

func GenerateSignedPreKey(identityKeyPair *identity.KeyPair, signedPreKeyID uint32, serializer record.SignedPreKeySerializer) (*record.SignedPreKey, error)

GenerateSignedPreKey generates a signed PreKey.
