Trait serde_encrypt::AsSharedKey

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
    ) -> &GenericArray<u8, UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>> { ... }
}

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

RNG singleton

Required methods

fn from_array(key: [u8; 32]) -> Self

Constructor from secret bytes.

fn as_slice(&self) -> &[u8]

Ref to 32-byte slice

Provided methods

fn generate() -> Self

Generates secure random key.

Random number generator which implements CryptRng is used internally.

fn to_chacha_key(
    &self
) -> &GenericArray<u8, UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>>

Makes chacha20poly1305::Key
