Struct Encryptor 

pub struct Encryptor<W: Write> { /* private fields */ }

A Writer that symmetrically encrypts data as it is written.

Implementations

impl<W: Write> Encryptor<W>

pub fn new( algo: SymmetricAlgorithm, mode: BlockCipherMode, padding: PaddingMode, key: &SessionKey, iv: Option<&[u8]>, sink: W, ) -> Result<Self>

Instantiate a new symmetric encryptor.

If iv is None, and the given mode requires an IV, an all-zero IV is used.

pub fn finalize(self) -> Result<W>

Finish encryption and write last partial block.

Trait Implementations

impl<W: Write> Drop for Encryptor<W>

fn drop(&mut self)

Executes the destructor for this type.

impl<W: Write> Write for Encryptor<W>

fn write(&mut self, buf: &[u8]) -> Result<usize>

Writes a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
