Struct EncryptionKey 

pub struct EncryptionKey<CS: CipherSuite> { /* private fields */ }

The Device Encryption Key.

Implementations

impl<CS: CipherSuite> EncryptionKey<CS>

pub fn new<R: Csprng>(rng: &mut R) -> Self

Creates a random EncryptionKey

impl<CS: CipherSuite> EncryptionKey<CS>

pub fn id(&self) -> Result<EncryptionKeyId, IdError>

Uniquely identifies the EncryptionKey Two keys with the same ID are the same key.

pub fn public(&self) -> Result<EncryptionPublicKey<CS>, PkError>

Returns the public half of the key.

impl<CS: CipherSuite> EncryptionKey<CS>

pub fn open_group_key( &self, enc: &Encap<CS>, ciphertext: EncryptedGroupKey<CS>, group: GroupId, ) -> Result<GroupKey<CS>, Error>

Decrypts and authenticates a GroupKey received from a peer.

impl<CS: CipherSuite> EncryptionKey<CS>

pub fn seal_psk_seed<R: Csprng>( &self, rng: &mut R, seed: &PskSeed<CS>, peer_pk: &EncryptionPublicKey<CS>, group: &GroupId, ) -> Result<(Encap<CS>, EncryptedPskSeed<CS>), Error>

Available on crate feature tls only.

Uses self to encrypt and authenticate the PskSeed such that it can only be decrypted by the holder of the private half of peer_pk.

It is an error if pk is the public key for self.

pub fn open_psk_seed( &self, encap: &Encap<CS>, ciphertext: EncryptedPskSeed<CS>, peer_pk: &EncryptionPublicKey<CS>, group: &GroupId, ) -> Result<PskSeed<CS>, Error>

Available on crate feature tls only.

Uses self to decrypt and authenticate a PskSeed that was encrypted by peer_pk.

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<CS: CipherSuite> ConstantTimeEq for EncryptionKey<CS>

fn ct_eq(&self, other: &Self) -> Choice
