Struct StreamCipher 

pub struct StreamCipher { /* private fields */ }

Stream cipher for large file encryption.

Each chunk is independently authenticated, allowing:

• Constant memory usage regardless of file size
• Early detection of tampering
• Potential for parallel processing

Implementations

impl StreamCipher

pub fn new(key: [u8; 32]) -> Self

Create a new stream cipher with the given key.

pub fn with_chunk_size(key: [u8; 32], chunk_size: usize) -> Self

Create with custom chunk size.

pub fn chunk_size(&self) -> usize

Get the chunk size.

pub fn encrypt_stream<'a>( &'a self, data: &'a [u8], ) -> Result<StreamEncryptor<'a>>

Encrypt a stream of data.

Returns an iterator over encrypted chunks. First chunk is the header containing stream salt.

pub fn decrypt_stream(&self, encrypted: &[u8]) -> Result<Vec<u8>>

Decrypt a stream of encrypted chunks.

pub fn encrypt(&self, data: &[u8]) -> Result<Vec<u8>>

Encrypt entire data at once (convenience method).

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

Decrypt entire data at once (convenience method).

Trait Implementations

impl Drop for StreamCipher

fn drop(&mut self)

Executes the destructor for this type.

impl Zeroize for StreamCipher

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
