EphemeralSecret

✓ use x25519_dalek::{EphemeralSecret, PublicKey};

Performs X25519 key exchange between two parties.

use x25519_dalek::{EphemeralSecret, PublicKey}; use rand::rngs::OsRng; let alice_secret = EphemeralSecret::new(OsRng); let alice_public = PublicKey::from(&alice_secret); let bob_secret = EphemeralSecret::new(OsRng); let bob_public = PublicKey::from(&bob_secret); let alice_shared = alice_secret.diffie_hellman(&bob_public); let bob_shared = bob_secret.diffie_hellman(&alice_public); assert_eq!(alice_shared.as_bytes(), bob_shared.as_bytes());

Debug

Known issues

gotchaEphemeralSecret should not be reused; use StaticSecret for long-term keys.

fix

Use `StaticSecret` instead of `EphemeralSecret` for persistent keys.
