Struct ffsend_api::pipe::crypto::ece::EceCrypt

pub struct EceCrypt { /* fields omitted */ }

Something that can encrypt or decrypt given data using ECE.

Methods

impl EceCrypt

pub fn new(
    mode: CryptMode,
    len: usize,
    ikm: Vec<u8>,
    salt: Option<Vec<u8>>
) -> Self

Construct a new ECE crypter pipe.

It is highly recommended to use the encrypt() and decrypt() methods instead for constructing a new crypter.

The size in bytes of the plaintext data must be given as len. The input key material must be given as ikm. When encrypting, a salt must be specified.

pub fn encrypt(len: usize, ikm: Vec<u8>, salt: Option<Vec<u8>>) -> Self

Create an ECE encryptor.

The size in bytes of the plaintext data that is encrypted decrypt must be given as len. The input key material must be given as ikm. The salt is optional and will be randomly generated if None.

pub fn decrypt(len: usize, ikm: Vec<u8>) -> Self

Create an ECE decryptor.

The size in bytes of the plaintext data that is decrypted decrypt must be given as len. The input key material must be given as ikm.

Trait Implementations

impl Crypt for EceCrypt

fn crypt(&mut self, input: &[u8]) -> (usize, Option<Vec<u8>>)

Encrypt/decrypt bytes from input, return the result.

impl Pipe for EceCrypt

type Reader = EceReader

The wrapping reader type used for this pipe.

type Writer = EceWriter

The wrapping writer type used for this pipe.

fn pipe(&mut self, input: &[u8]) -> (usize, Option<Vec<u8>>)

Pipe bytes from input, monitor/transform it, return the output.

fn reader(self, inner: Box<dyn Read>) -> Self::Reader

Wrap the inner reader, bytes that are read are transformed through this pipe.

fn writer(self, inner: Box<dyn Write>) -> Self::Writer

Wrap the inner writer, bytes that are read are transformed through this pipe.

fn pipe_transparent(&self, input: &[u8]) -> (usize, Option<Vec<u8>>)

Transparently pipe input by immediately returning it.

impl PipeRead<EceCrypt> for EceReader

fn new(crypt: EceCrypt, inner: Box<dyn Read>) -> Self

Wrap the given inner reader, transform data using crypt.

impl PipeWrite<EceCrypt> for EceWriter

fn new(crypt: EceCrypt, inner: Box<dyn Write>) -> Self

Wrap the given inner writer, transform data using crypt.

impl PipeLen for EceCrypt

fn len_in(&self) -> usize

The number of bytes that are transfered into the pipe if fixed.

fn len_out(&self) -> usize

The number of bytes that are transfered out of the pipe if fixed.
