[][src]Struct sequoia_openpgp::crypto::SessionKey

pub struct SessionKey(_);

Holds a session key.

The session key is cleared when dropped. Sequoia uses this type to ensure that session keys are not left in memory returned to the allocator.

Session keys can be generated using SessionKey::new, or converted from various types using From.

Methods

impl SessionKey[src]

pub fn new(size: usize) -> Self[src]

Creates a new session key.

Creates a new session key size bytes in length initialized using a strong cryptographic number generator.

Examples

This creates a session key and encrypts it for a given recipient key producing a PKESK packet.

use sequoia_openpgp as openpgp;
use openpgp::types::{Curve, SymmetricAlgorithm};
use openpgp::crypto::SessionKey;
use openpgp::packet::prelude::*;

let cipher = SymmetricAlgorithm::AES256;
let sk = SessionKey::new(cipher.key_size().unwrap());

let key: Key<key::SecretParts, key::UnspecifiedRole> =
    Key4::generate_ecc(false, Curve::Cv25519)?.into();

let pkesk: PKESK =
    PKESK3::for_recipient(cipher, &sk, &key)?.into();
