source · 
pub struct SealingKey { /* private fields */ }
Expand description

A key for sealing packets.

Implementations§

source§

impl SealingKey

source

pub fn new(key_material: &[u8; 64]) -> Self

Constructs a new SealingKey.

source

pub fn seal_in_place( &self, sequence_number: u32, plaintext_in_ciphertext_out: &mut [u8], tag_out: &mut [u8; 16], )

Seals (encrypts and signs) a packet.

On input, plaintext_in_ciphertext_out must contain the unencrypted packet_length||plaintext where plaintext is the padding_length||payload||random padding. It will be overwritten by encrypted_packet_length||ciphertext, where encrypted_packet_length is encrypted with K_1 and ciphertext is encrypted by K_2.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
