Property Type Description
AESAuthCode byte[]
baseOutputStream_ Stream
deflater_ ICSharpCode.SharpZipLib.Zip.Compression.Deflater

Public Methods

Method Description
DeflaterOutputStream ( Stream baseOutputStream ) : System

Creates a new DeflaterOutputStream with a default Deflater and default buffer size.

DeflaterOutputStream ( Stream baseOutputStream, Deflater deflater ) : System

Creates a new DeflaterOutputStream with the given Deflater and default buffer size.

DeflaterOutputStream ( Stream baseOutputStream, Deflater deflater, int bufferSize ) : System

Creates a new DeflaterOutputStream with the given Deflater and buffer size.

Finish ( ) : void

Finishes the stream by calling finish() on the deflater.

Flush ( ) : void

Flushes the stream by calling Flush on the deflater and then on the underlying stream. This ensures that all bytes are flushed.

Read ( byte buffer, int offset, int count ) : int

Read a block of bytes from stream

ReadByte ( ) : int

Read a byte from stream advancing position by one

Seek ( long offset, SeekOrigin origin ) : long

Sets the current position of this stream to the given value. Not supported by this class!

SetLength ( long value ) : void

Sets the length of this stream to the given value. Not supported by this class!

Write ( byte buffer, int offset, int count ) : void

Writes bytes from an array to the compressed stream.

WriteByte ( byte value ) : void

Writes a single byte to the compressed output stream.

Protected Methods

Method Description
Deflate ( ) : void

Deflates everything in the input buffers. This will call def.deflate() until all bytes from the input buffers are processed.

Dispose ( bool disposing ) : void

Calls Finish and closes the underlying stream when is true.

EncryptBlock ( byte buffer, int offset, int length ) : void

Encrypt a block of data

InitializeAESPassword ( ZipEntry entry, string rawPassword, byte &salt, byte &pwdVerifier ) : void

Initializes encryption keys based on given password.

InitializePassword ( string password ) : void

Initializes encryption keys based on given password.

Private Methods

Method Description
GetAuthCodeIfAES ( ) : void
