Enum socket_collection::EncryptContext

pub enum EncryptContext {
    Null,
    Authenticated {
        shared_key: SharedSecretKey,
    },
    AnonymousEncrypt {
        their_pk: PublicEncryptKey,
    },
}

Simplifies encryption by holding the necessary context - encryption keys. Allows "null" encryption where data is only serialized. See: null object pattern.

Variants

Null

No encryption.

Authenticated

Encryption + authentication

Fields of Authenticated

shared_key: SharedSecretKey

AnonymousEncrypt

No message authentication. Only encrypt operation is allowed.

Fields of AnonymousEncrypt

their_pk: PublicEncryptKey

Their public key.

Methods

impl EncryptContext

pub fn null() -> Self

Contructs "null" encryption context which actually does no encryption. In this case data is simply serialized but not encrypted.

pub fn authenticated(shared_key: SharedSecretKey) -> Self

Construct crypto context that encrypts and authenticate messages.

pub fn anonymous_encrypt(their_pk: PublicEncryptKey) -> Self

Constructs crypto context that is only meant for unauthenticated encryption.

pub fn encrypt<T: Serialize>(&self, msg: &T) -> Res<Vec<u8>>

Serialize given structure and encrypt it.

pub fn encrypted_size_len(&self) -> usize

Our data size is 32 bit number. When we encrypt this number with safe_crypto, we get a constant size byte array. This size depends on encryption variation though.

Trait Implementations

impl Clone for EncryptContext

fn clone(&self) -> EncryptContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for EncryptContext

fn default() -> Self

Default is "null" encryption.

impl Debug for EncryptContext

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
