* QUIC Stateless Reset Token Generator
|
|
* ====================================
|
|
*
|
|
* This generates 16-byte QUIC Stateless Reset Tokens given a secret symmetric
|
|
* key and a DCID. Because the output is deterministic with regards to these
|
|
* inputs, assuming the same key is used between invocations of a process, we
|
|
* are able to generate the same stateless reset token in a subsequent process,
|
|
* thereby allowing us to achieve stateless reset of a peer which still thinks
|
|
* it is connected to a past process at the same UDP address.
