Struct ssh_cipher::Decryptor

pub struct Decryptor { /* private fields */ }

Available on crate features aes-cbc or aes-ctr or tdes only.

Stateful decryptor object for unauthenticated SSH symmetric ciphers.

Note that this deliberately does not support AEAD modes such as AES-GCM and ChaCha20Poly1305, which are one-shot by design.

Implementations

impl Decryptor

pub fn new(cipher: Cipher, key: &[u8], iv: &[u8]) -> Result<Self>

Create a new decryptor object with the given Cipher, key, and IV.

pub fn cipher(&self) -> Cipher

Get the cipher for this decryptor.

pub fn decrypt(&mut self, buffer: &mut [u8]) -> Result<()>

Decrypt the given buffer in place.

Returns Error::Length in the event that buffer is not a multiple of the cipher’s block size.

pub fn peek_decrypt(&self, buffer: &mut [u8]) -> Result<()>

Decrypt the given buffer in place without altering the internal state

Returns Error::Length in the event that buffer is not a multiple of the cipher’s block size.
