Struct miscreant::stream::Decryptor

pub struct Decryptor<A: Aead> { /* fields omitted */ }

A STREAM decryptor with a 32-bit counter, generalized for any AEAD algorithm

This corresponds to the 𝒟 stream decryptor object as defined in the paper Online Authenticated-Encryption and its Nonce-Reuse Misuse-Resistance

Implementations

impl<A: Aead> Decryptor<A>

pub fn new(key: &[u8], nonce: &[u8]) -> Self

Create a new STREAM decryptor, initialized with a given key and nonce.

Panics if the key or nonce is the wrong size.

pub fn decrypt_next_in_place<'a>(
    &mut self,
    ad: &[u8],
    buffer: &'a mut [u8]
) -> Result<&'a [u8], Error>

Decrypt the next message in the stream in-place

pub fn decrypt_last_in_place<'a>(
    self,
    ad: &[u8],
    buffer: &'a mut [u8]
) -> Result<&'a [u8], Error>

Decrypt the final message in-place, consuming the stream decryptor

pub fn decrypt_next(
    &mut self,
    ad: &[u8],
    ciphertext: &[u8]
) -> Result<Vec<u8>, Error>

Decrypt the next message in the stream, allocating and returning a Vec<u8> for the plaintext

pub fn decrypt_last(
    self,
    ad: &[u8],
    ciphertext: &[u8]
) -> Result<Vec<u8>, Error>

Decrypt the next message in the stream, allocating and returning a Vec<u8> for the plaintext
