Struct PacketKey

pub(crate) struct PacketKey {
    key: LessSafeKey,
    iv: Iv,
    confidentiality_limit: u64,

}

Fields

key: LessSafeKey

Encrypts or decrypts a packet’s payload

iv: Iv

Computes unique nonces for each packet

confidentiality_limit: u64

Confidentiality limit (see quic::PacketKey::confidentiality_limit)

integrity_limit: u64

Integrity limit (see quic::PacketKey::integrity_limit)

Implementations

impl PacketKey

pub(crate) fn new( key: AeadKey, iv: Iv, confidentiality_limit: u64, integrity_limit: u64, aead_algorithm: &'static Algorithm, ) -> Self

Trait Implementations

impl PacketKey for PacketKey

fn decrypt_in_place<'a>( &self, packet_number: u64, header: &[u8], payload: &'a mut [u8], ) -> Result<&'a [u8], Error>

Decrypt a QUIC packet

Takes the packet header, which is used as the additional authenticated data, and the payload, which includes the authentication tag.

If the return value is Ok, the decrypted payload can be found in payload, up to the length found in the return value.

fn tag_len(&self) -> usize

Tag length for the underlying AEAD algorithm

fn confidentiality_limit(&self) -> u64

Confidentiality limit (see quic::PacketKey::confidentiality_limit)

fn integrity_limit(&self) -> u64

Integrity limit (see quic::PacketKey::integrity_limit)

fn encrypt_in_place( &self, packet_number: u64, header: &[u8], payload: &mut [u8], ) -> Result<Tag, Error>

Encrypt a QUIC packet
