impl SealingKey
sourcepub fn new(key_material: &[u8; 64]) -> SealingKey
pub fn new(key_material: &[u8; 64]) -> SealingKey
Constructs a new SealingKey
.
sourcepub fn seal_in_place(
&self,
sequence_number: u32,
plaintext_in_ciphertext_out: &mut [u8],
tag_out: &mut [u8; 16]
)
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
.
