Struct magic_wormhole::Key

pub struct Key<P: KeyPurpose>(pub Box<Key>, _);

The symmetric encryption key used to communicate with the other side.

You don’t need to do any crypto, but you might need it to derive subkeys for sub-protocols.

Tuple Fields

0: Box<Key>

Implementations

impl Key<WormholeKey>

pub fn derive_transit_key(&self, appid: &AppID) -> Key<TransitKey>

Derive the sub-key used for transit

This one’s a bit special, since the Wormhole’s AppID is included in the purpose. Different kinds of applications can’t talk to each other, not even accidentally, by design.

The new key is derived with the "{appid}/transit-key" purpose.

impl<P: KeyPurpose> Key<P>

pub fn new(key: Box<Key>) -> Self

pub fn to_hex(&self) -> String

pub fn derive_subkey_from_purpose<NewP: KeyPurpose>( &self, purpose: &str ) -> Key<NewP>

Derive a new sub-key from this one

Trait Implementations

impl<P: Clone + KeyPurpose> Clone for Key<P>

fn clone(&self) -> Key<P>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

where Box<Key>: Deref,

type Target = <Box<GenericArray<u8, UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>>> as Deref>::Target

The resulting type after dereferencing.

Dereferences the value.
