public int getHandshakeTimeoutMillis()

setHandshakeTimeoutMillis

public void setHandshakeTimeoutMillis(int handshakeTimeoutMillis)

getMySessionKey

public SymmetricKey getMySessionKey()

getRemoteSessionKey

public SymmetricKey getRemoteSessionKey()

setRemoteKey

public void setRemoteKey(@org.checkerframework.checker.nullness.qual.NonNull byte[] packedKey)
                  throws EncryptionError

Unpack the remote public key, check if it is trusted, if the remoteKey is null, saves new value, otherwise checks that it is the same key, or throws IllegalArgumentException.

Set the remote key and accurately check that it was not spoofed, e.g. only one key could be set event several times. Because of the p2p nature of the connection we have no guarantee which way the remote key will arrive first (in the "hello" command from the remote or from the hello answer from the remote), this method allows to set the remote key in right mode.

Parameters:

packedKey - packed remoteKey

Throws:

java.lang.IllegalArgumentException - if the remoteKey is already set to a different key.
