Enum p2p::CryptoContext

pub enum CryptoContext {
    Null,
    Authenticated {
        their_pk: PublicKey,
        our_sk: SecretKey,
    },
    AnonymousDecrypt {
        our_pk: PublicKey,
        our_sk: SecretKey,
    },
    AnonymousEncrypt {
        their_pk: PublicKey,
    },
}

Simplifies encryption/decryption 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

their_pk: PublicKey	Their public key.
our_sk: SecretKey	Our secret key.

AnonymousDecrypt

No message authentication. Only decrypt operation is allowed.

Fields of AnonymousDecrypt

our_pk: PublicKey	Our private key.
our_sk: SecretKey	Our secret key.

AnonymousEncrypt

No message authentication. Only encrypt operation is allowed.

Fields of AnonymousEncrypt

their_pk: PublicKey

Their public key.

Methods

impl CryptoContext

pub fn authenticated(their_pk: PublicKey, our_sk: SecretKey) -> Self

Construct crypto context that encrypts and authenticate messages.

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 anonymous_decrypt(our_pk: PublicKey, our_sk: SecretKey) -> Self

Constructs crypto context that is only meant for unauthenticated deryption.

pub fn anonymous_encrypt(their_pk: PublicKey) -> Self

Constructs crypto context that is only meant for unauthenticated encryption.

pub fn encrypt<T: Serialize>(&self, msg: &T) -> Result<BytesMut, CryptoError>

Serialize given structure and encrypt it.

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

Decrypt given buffer and deserialize into structure.

Trait Implementations

impl Clone for CryptoContext

fn clone(&self) -> CryptoContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CryptoContext

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

Formats the value using the given formatter.
