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.

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.
