Trait PacketKey 

pub trait PacketKey: Send {
    // Required methods
    fn seal(&self, pn: u64, header: &[u8], payload: &mut [u8], tag: &mut [u8]);
    fn open(
        &self,
        pn: u64,
        header: &[u8],

    ) -> Result<usize, ()>;
    fn tag_len(&self) -> usize;
    fn confidentiality_limit(&self) -> u64;
    fn integrity_limit(&self) -> u64;
}

AEAD packet protection for one direction.

Required Methods

fn seal(&self, pn: u64, header: &[u8], payload: &mut [u8], tag: &mut [u8])

Encrypts payload in place and writes the tag (tag_len() bytes) to tag.

fn open( &self, pn: u64, header: &[u8], payload_and_tag: &mut [u8], ) -> Result<usize, ()>

Decrypts payload_and_tag in place; returns the plaintext length.

fn tag_len(&self) -> usize

fn confidentiality_limit(&self) -> u64

Packets that may be sealed before a key update is required (RFC 9001 §6.6).

fn integrity_limit(&self) -> u64

Failed decryptions tolerated before the connection must close (RFC 9001 §6.6).

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
