Struct AesGcmFileWrite 

pub struct AesGcmFileWrite { /* private fields */ }

Transparent encryption of AGS1 stream-encrypted files.

Implements the FileWrite trait, buffering plaintext and emitting encrypted AGS1 blocks. This is the streaming write counterpart to AesGcmFileRead.

Usage

// (ignored: requires async runtime and concrete FileRead/FileWrite impls)
let writer = AesGcmFileWrite::new(
    inner_writer,       // Box<dyn FileWrite> for the output file
    cipher,             // Arc<AesGcmCipher> with the DEK
    aad_prefix.to_vec(),
);

writer.write(plaintext_chunk).await?;
writer.close().await?;

Implementations

impl AesGcmFileWrite

pub fn new( inner: Box<dyn FileWrite>, cipher: Arc<AesGcmCipher>, aad_prefix: impl Into<Box<[u8]>>, ) -> Self

Creates a new AesGcmFileWrite for encrypting to AGS1 format.

No I/O is performed until write() or close() is called.

Trait Implementations

impl FileWrite for AesGcmFileWrite

fn write<'life0, 'async_trait>( &'life0 mut self, bs: Bytes, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Write bytes to file.

fn close<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,
