Trait serde_encrypt::AsSharedKey [−][src]
pub trait AsSharedKey { type R: RngSingleton; fn from_array(key: [u8; 32]) -> Self; fn as_slice(&self) -> &[u8]; fn generate() -> Self { ... } fn to_chacha_key(
&self

Expand description
32-byte key shared among sender and receiver secretly.
The reason why this is not a struct but a trait is:
- shared key should be serialized and encrypted in order to be shared among peers
- but this -core trait is serialization agnostic.
So, implementators of this trait is expected to have serde::{Serialize, Deserialize}
and SerdeSerializePublicKey
trait bounds.
Associated Types
type R: RngSingleton
type R: RngSingleton
RNG singleton
Required methods
fn from_array(key: [u8; 32]) -> Self
fn from_array(key: [u8; 32]) -> Self
Constructor from secret bytes.
Provided methods
Generates secure random key.
Random number generator which implements CryptRng
is used internally.
