Enum socket_collection::DecryptContext

pub enum DecryptContext {
    Null,
    Authenticated {
        shared_key: SharedSecretKey,
    },
    AnonymousDecrypt {
        our_pk: PublicEncryptKey,
        our_sk: SecretEncryptKey,
    },
}

Simplifies decryption by holding the necessary context - keys to decrypt data. Allows "null" decryption where data is only deserialized. See: null object pattern.

Variants

Null

No encryption.

Authenticated

Encryption + authentication

Fields of Authenticated

shared_key: SharedSecretKey

AnonymousDecrypt

No message authentication. Only decrypt operation is allowed.

Fields of AnonymousDecrypt

our_pk: PublicEncryptKey

Our private key.

our_sk: SecretEncryptKey

Our secret key.

Methods

impl DecryptContext

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_decrypt(     our_pk: PublicEncryptKey,     our_sk: SecretEncryptKey ) -> Self

Constructs crypto context that is only meant for unauthenticated decryption.

pub fn decrypt<T>(&self, msg: &[u8]) -> Res<T> where     T: Serialize + DeserializeOwned,

Decrypt given buffer and deserialize into structure.

pub fn encrypted_size_len(&self) -> usize

The length of encrypted size variable. The returned value must match EncryptContext::encrypted_size_len(), so that we could be able to decrypt it.

Trait Implementations

impl Clone for DecryptContext

fn clone(&self) -> DecryptContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for DecryptContext

fn default() -> Self

Default is "null" encryption.

impl Debug for DecryptContext

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

Formats the value using the given formatter.
