Buffering may be causing you issues. Perhaps it would be easier to
prototype your code with strings:
StringSource( plainText, true,
new StreamTransformationFilter(
Encryptor,
new StringSink( cipherText )
) // StreamTransformationFilter
); // StringSource
With strings working, then attempt to isolate the istream issue. I
can't speak about Borland, but I know Microsoft streams have some
interesting side effects at times.
