Struct holochain::prelude::kitsune_p2p::dependencies::kitsune_p2p_types::dependencies::rustls::quic::HeaderProtectionKey

pub struct HeaderProtectionKey(_);

A QUIC header protection key

Implementations

impl HeaderProtectionKey

pub fn encrypt_in_place(
    &self,
    sample: &[u8],
    first: &mut u8,
    packet_number: &mut [u8]
) -> Result<(), Error>

Adds QUIC Header Protection.

sample must contain the sample of encrypted payload; see Header Protection Sample.

first must reference the first byte of the header, referred to as packet[0] in Header Protection Application.

packet_number must reference the Packet Number field; this is packet[pn_offset:pn_offset+pn_length] in Header Protection Application.

Returns an error without modifying anything if sample is not the correct length (see Header Protection Sample and Self::sample_len()), or packet_number is longer than allowed (see Packet Number Encoding and Decoding).

Otherwise, first and packet_number will have the header protection added.

pub fn decrypt_in_place(
    &self,
    sample: &[u8],
    first: &mut u8,
    packet_number: &mut [u8]
) -> Result<(), Error>

Removes QUIC Header Protection.

sample must contain the sample of encrypted payload; see Header Protection Sample.

first must reference the first byte of the header, referred to as packet[0] in Header Protection Application.

packet_number must reference the Packet Number field; this is packet[pn_offset:pn_offset+pn_length] in Header Protection Application.

Returns an error without modifying anything if sample is not the correct length (see Header Protection Sample and Self::sample_len()), or packet_number is longer than allowed (see Packet Number Encoding and Decoding).

Otherwise, first and packet_number will have the header protection removed.
