3613 | | * is not a confidentiality-critical secret in the same sense as |
3614 | | * the traffic key; losing it does not compromise plaintext. |
3615 | | * |
3616 | | * Scope: |
3617 | | * - TLS 1.3 only. TLS 1.2 additionally reads |
3618 | | * keys->{client,server}_write_key for rehandshake/secure |
3619 | | * renegotiation flows. |
3620 | | * - Non-DTLS. Dtls13EpochCopyKeys (called from Dtls13NewEpoch) |
3621 | | * references keys->*_write_key for epoch switching; DTLS 1.3 |
3622 | | * needs separate analysis. |
3623 | | * - Non-QUIC. QUIC traffic secrets live outside these buffers |
3624 | | * but the interaction with stack-installed QUIC handlers has |
3625 | | * not been audited; exclude until it is. |
3626 | | * |
