Please buy yourself a book about cryptopraphic methods. You will see, that
3DES is a symmetric cipher. Symmetric ciphers are working on chunks of a given
size (determined by the block length, which is corresponding to the key
length).
Therefore you will receive an encrypted length of 12,000bytes plus some
bytes for padding.
