Struct SphinxPacket 

pub struct SphinxPacket(/* private fields */);

Fixed-size (32KB) encrypted packet: [Header: 1024][Nonce: 12][Ciphertext + Tag].

Implementations

impl SphinxPacket

pub fn new( payload: &[u8], key: &[u8; 32], nonce: &[u8; 12], ) -> Result<Self, PacketError>

Encrypts a variable-length payload into a fixed-size 32KB packet.

pub fn unwrap(&self, key: &[u8; 32]) -> Result<Vec<u8>, PacketError>

Decrypts and unpads the packet to recover the original payload.

pub fn as_bytes(&self) -> &[u8]

Returns the raw packet bytes (always exactly PACKET_SIZE).

pub fn into_bytes(self) -> Vec<u8>

Consumes the packet, returning the underlying buffer.

pub fn from_bytes(bytes: Vec<u8>) -> Result<Self, PacketError>

Creates a SphinxPacket from raw bytes. Fails if not exactly PACKET_SIZE.

pub fn header_mut(&mut self) -> &mut [u8]

Mutable access to the header section for Sphinx routing info.

pub fn header(&self) -> &[u8]

Read access to the header section.
