Detailed Description

Simple rotary encrypt/decrypt interface. Fast and cheap. no BlockAlignSize.

Constructor & Destructor Documentation

Member Function Documentation

◆ Cipher()

HRESULT GrayLib::cCipherRotary::Cipher	(	BYTE *	pOutput,
		const BYTE *	pInput,
		size_t	nSizeBytes
	)

overridevirtual

Symmetric cipher.

Note: pOutput == pInput is OK.

Returns: <0 = error. Amount of data i could actually process (some may be dropped for alignment)

Reimplemented from GrayLib::cCipherBase.

◆ InitCryptMasterKey()

bool GrayLib::cCipherRotary::InitCryptMasterKey	(	UINT32	dwVersion,
		UINT32	dwKeyHi,
		UINT32	dwKeyLo
	)

protected

◆ isMasterKeySet()

bool GrayLib::cCipherRotary::isMasterKeySet ( ) const

inlineprotected

◆ put_CipherKey()

HRESULT GrayLib::cCipherRotary::put_CipherKey ( UINT32 uSeed )

protected

Generate the decrypt key based on the uSeed/IP we get from the client.

uSeed is usually an IP address for the connection.

◆ SetCipherKey()

HRESULT GrayLib::cCipherRotary::SetCipherKey	(	const void *	pKeyData = `nullptr`,
		size_t	nKeySize = `0`
	)

overridevirtual

Reimplemented from GrayLib::cCipherBase.

◆ UNITTEST_FRIEND()

GrayLib::cCipherRotary::UNITTEST_FRIEND ( cCipherRotary )
