Inheritance diagram for CipherStream:

Public Member Functions
	CipherStream (IMCStream *baseStream, std::byte *key, std::byte *iv)
	Construct a new Cipher Stream object.
	~CipherStream ()
	Destroy the Cipher Stream object.
void	read (std::byte *buffer, std::size_t offset, std::size_t len) override
	Reads from an encrypted stream.
void	write (const std::byte *buffer, std::size_t offset, std::size_t len) override
	Writes to an encrypted stream.
size_t	available () override
	Gets the number of available bytes Returns the number of available bytes in the sub-stream. Not accurate as to the real length because it doesn't account for the encryption.
void	finishPacketWrite (const std::byte *packetData, size_t len) override
	Finishes to write the packet in a Minecrafty way.
void	flush () override
	Flushes the base stream.

Detailed Description

AES 128bit CFB8 Cipher stream.

Cipher stream for minecraft, is updates for every packet and not finalized then restarted.

Constructor & Destructor Documentation

CipherStream()

CipherStream::CipherStream	(	IMCStream *	baseStream,
		std::byte *	key,
		std::byte *	iv )

Construct a new Cipher Stream object.

Parameters

baseStream	the stream to IO on, the class takes ownership
key	the key for the AES cipher
iv	the IV for the AES cipher

Member Function Documentation

available()

size_t CipherStream::available ( )

overridevirtual

Gets the number of available bytes Returns the number of available bytes in the sub-stream. Not accurate as to the real length because it doesn't account for the encryption.

Warning

Only use to check if there are bytes to read.

Returns

size_t the number of available bytes

Implements IMCStream.

finishPacketWrite()

void CipherStream::finishPacketWrite ( const std::byte * packetData, size_t len )

overridevirtual

Finishes to write the packet in a Minecrafty way.

Parameters

packetData	the packet data
len	the length of the packet data

Implements IMCStream.

flush()

void CipherStream::flush ( )

overridevirtual

Flushes the base stream.

Implements IMCStream.

read()

void CipherStream::read ( std::byte * buffer, std::size_t offset, std::size_t len )

overridevirtual

Reads from an encrypted stream.

Parameters

buffer	the buffer to write to
offset	the offset to start writing to
len	the length to read from baseStream and write to buffer

Implements IMCStream.

write()

void CipherStream::write ( const std::byte * buffer, std::size_t offset, std::size_t len )

overridevirtual

Writes to an encrypted stream.

Parameters

buffer	the buffer to read from
offset	the offset to start reading from
len	the length to read from buffer

Implements IMCStream.
