Detailed Description

Performs the traditional zip encryption.

bool CZipCrc32Cryptograph::CanHandle ( int iEncryptionMethod ) [inline, virtual]

Returns the value indicating whether the current compressor can handle the given encryption method.

Parameters:

iEncryptionMethod

The encryption method to test. Can be one of EncryptionMethod values.

Returns:: true, if the current compressor can handle the given encryption method; false otherwise.

Reimplemented from CZipCryptograph.

void CZipCrc32Cryptograph::Decode	(	char *	pBuffer,
		DWORD	uSize
	)			`[inline, virtual]`

Decodes the given data.

Parameters:

	pBuffer	The buffer that holds the data to decode and that receives the results.
	uSize	The size of pBuffer.

void CZipCrc32Cryptograph::Encode	(	char *	pBuffer,
		DWORD	uSize
	)			`[inline, virtual]`

Encodes the given data.

Parameters:

	pBuffer	The buffer that holds the data to encode and that receives the results.
	uSize	The size of pBuffer.

static const DWORD* CZipCrc32Cryptograph::GetCRCTable ( ) [inline, static]

Returns the CRC table.

static DWORD CZipCrc32Cryptograph::GetEncryptedInfoSizeAfterData ( ) [inline, static]

static DWORD CZipCrc32Cryptograph::GetEncryptedInfoSizeBeforeData ( ) [inline, static]

bool CZipCrc32Cryptograph::InitDecode	(	CZipAutoBuffer &	password,
		CZipFileHeader &	currentFile,
		CZipStorage &	storage
	)			`[virtual]`

The method called when an existing file is opened for extraction.

Parameters:

	password	The supplied password with the CZipArchive::SetPassword method.
	currentFile	The file being decoded and extracted.
	storage	The current CZipStorage.

Returns:: true, if the password is initially considered correct; false otherwise.

void CZipCrc32Cryptograph::InitEncode	(	CZipAutoBuffer &	password,
		CZipFileHeader &	currentFile,
		CZipStorage &	storage
	)			`[virtual]`

The method called when a new file is opened for compression.

Parameters:

	password	The supplied password with the CZipArchive::SetPassword method.
	currentFile	The file being compressed and encoded.
	storage	The current CZipStorage.
