Member Function Documentation

bool UT_BlowfishStreamDecryptor::decrypt	(	const uint8 *	input,
		uint8 *	output,
		int	input_size
	)

Decrypts the input buffer into output buffer. See UT_Blowfish::decrypt() for details.

static int UT_BlowfishStreamDecryptor::getBlockSize ( )

static

Wrapper for UT_Blowfish::getBlockSize()

static int UT_BlowfishStreamDecryptor::getCryptBufferSize ( int  max_buffer_size )

static

Wrapper for UT_Blowfish::getCryptBufferSize()

static int UT_BlowfishStreamDecryptor::getEncryptedSize ( int  plain_text_size )

int64 UT_BlowfishStreamDecryptor::getMemoryUsage

(

bool

inclusive

)

const

Gets the amount of memory owned by this UT_BlowfishStreamDecryptor.

static bool UT_BlowfishStreamDecryptor::getPlainTextLength ( const char *  preamble, int  preamble_length, int64 &  length  )

static

Obtains the plain-text length that is encoded in the cipher.

static int UT_BlowfishStreamDecryptor::getPreambleSize ( )

static

Gets the preamble size. The pramble contains some meta-data such as plain-text size, encryption version, and magic number.

static bool UT_BlowfishStreamDecryptor::getVersion ( const char *  preamble, int  preamble_length, int &  version  )

static

Obtains the blowfish algorithm version used for the stream.
