Interface QuicTokenHandler

All Known Implementing Classes:

InsecureQuicTokenHandler

public interface QuicTokenHandler

Handle token related operations.

Method Summary

Modifier and Type	Method and Description
int	maxTokenLength() Return the maximal token length.
int	validateToken(io.netty.buffer.ByteBuf token, java.net.InetSocketAddress address) Validate the token and return the offset, -1 is returned if the token is not valid.
boolean	writeToken(io.netty.buffer.ByteBuf out, io.netty.buffer.ByteBuf dcid, java.net.InetSocketAddress address) Generate a new token for the given destination connection id and address.

Method Detail

writeToken

boolean writeToken(io.netty.buffer.ByteBuf out,
                   io.netty.buffer.ByteBuf dcid,
                   java.net.InetSocketAddress address)

Generate a new token for the given destination connection id and address. This token is written to out. If no token should be generated and so no token validation should take place at all this method should return false.

Parameters:

out - ByteBuf into which the token will be written.

dcid - the destination connection id. The ByteBuf.readableBytes() will be at most Quic.MAX_CONN_ID_LEN.

address - the InetSocketAddress of the sender.

Returns:

true if a token was written and so validation should happen, false otherwise.

validateToken

int validateToken(io.netty.buffer.ByteBuf token,
                  java.net.InetSocketAddress address)

Validate the token and return the offset, -1 is returned if the token is not valid.

Parameters:

token - the ByteBuf that contains the token. The ownership is not transferred.

address - the InetSocketAddress of the sender.

Returns:

the start index after the token or -1 if the token was not valid.

maxTokenLength

int maxTokenLength()

Return the maximal token length.

Returns:

the maximal supported token length.
