Member Function Documentation

virtual int UT_BlowfishEncryptFilter::beginFilter	(	char *	buffer,
		int	buffer_size,
		int	stream_size
	)			[virtual]

Writes out the length of the original stream to the buffer. It is used when decrypting.

Reimplemented from UT_StreamBufferFilter.

virtual int UT_BlowfishEncryptFilter::doFilterChunk	(	char *	buffer,
		int	data_size,
		int	buffer_size
	)			[virtual]

Performs the encryption of the data in the buffer.

Implements UT_StreamBufferFilter.

virtual int UT_BlowfishEncryptFilter::endFilter	(	char *	buffer,
		int	buffer_size
	)			[virtual]

Writes out any remaining ciphertext that has not been written out yet, and concludes encryption.

Reimplemented from UT_StreamBufferFilter.

virtual int UT_BlowfishEncryptFilter::getDataChunkLength

(

int

buffer_size

)

[virtual]

This method returns the the maximum input size (no larger than the specified buffer size) with which the filter can work, given the buffer size.

Reimplemented from UT_StreamBufferFilter.

static int UT_BlowfishEncryptFilter::getFilteredSize

(

int

original_size

)

[static]
