Struct X25519Recipient 

pub struct X25519Recipient { /* private fields */ }

A local X25519 recipient: the materialized static private key (Zeroizing) plus its key id.

Implementations

impl X25519Recipient

pub const fn new(key_id: KeyId, private: Zeroizing<[u8; 32]>) -> Self

Build a recipient from the 32 private key bytes.

pub fn from_private_slice( key_id: KeyId, bytes: &[u8], ) -> Result<Self, KeyLengthError>

Wrap a raw private key slice, failing closed (never indexing) on a wrong length. The caller should hand the slice from a Zeroizing buffer; the copy taken here is itself Zeroizing.

Errors

KeyLengthError if bytes is not exactly 32 bytes.

pub fn public(&self) -> X25519RecipientPublic

The corresponding public half (derived; the private never leaves).

Trait Implementations

impl Recipient for X25519Recipient

fn key_id(&self) -> &KeyId

The recipient (static X25519) key id.

async fn open( &self, request: &OpenRequest<'_>, ) -> Result<Zeroizing<Vec<u8>>, OpenError>

Open the message, returning the plaintext in a zeroizing buffer.
