* A QUIC client sends its first INITIAL packet with a random DCID, which
|
|
* is used to compute the secrets used for INITIAL packet encryption in both
|
|
* directions (both client-to-server and server-to-client).
|
|
*
|
|
* This function performs the necessary DCID-based key derivation, and then
|
|
* provides the derived key material for the INITIAL encryption level to a QRX
|
|
* instance, a QTX instance, or both.
|
|
*
|
|
* This function derives the necessary key material and then:
|
|
* - if qrx is non-NULL, provides the appropriate secret to it;
|
|
* - if qtx is non-NULL, provides the appropriate secret to it.
|
|
*
|
|
* If both qrx and qtx are NULL, this is a no-op. This function is equivalent to
|
|
* making the appropriate calls to ossl_qrx_provide_secret() and
|
|
* ossl_qtx_provide_secret().
|
|
*
|
|
* It is possible to use a QRX or QTX without ever calling this, for example if
|
|
* there is no desire to handle INITIAL packets (e.g. if a QRX/QTX is
|
|
* instantiated to succeed a previous QRX/QTX and handle a connection which is
|
|
* already established). However in this case you should make sure you call
|
|
* ossl_qrx_discard_enc_level(); see the header for that function for more
|
|
* details. Calling ossl_qtx_discard_enc_level() is not essential but could
|
|
* protect against programming errors.
|
|
*
|
|
* Returns 1 on success or 0 on error.
