Yes. And so does one byte. And so does 16 bytes. 4500 bytes goes to 4512.

incorrect, if you read any of my pervious posts you would know that i hve
said that i am not a cryptographer, this is my first attempt at a crypto
algorithm and that i am here asking for help in improving my algorithm. by
stating those three things i am taking any and all fault on myself and lack
of skill and understanding.

Yes, and you cut out what that was a reply to. You stated that blowfish
exploded the size of files. It does not. You kept insisting it does even
after others had pointed out it does not.

I have no idea how airplanes work. But I decided to build one in my
backyard. It has some novel idea taken from an F47 and a duck. I just
wanted to know if it would fly, and how to redesign it so it would fly
better. I am not interested in studying aerodynamics or any thing else,
but
want to sell this to home hobbyists.

bad analogy, i'm here to learn more than what i know from experts by putting
an algorithm i've devised up for comment and criticism. i did not mention
selling it to anyone either, this is a personal project to increase my
knowledge and understanding of crypto analysis and will remain so until i am
happy with it, which will probably be never. the challenge that was put
forward to me and others in my class back in college was to design a fast
algorithm that was at least 8-bit security, i've carried it past my studies
out of personal interest.

Fine. Remove the last half sentencei of my analogy.
Blowfish, AES,.... are well developed secure algorithms. Use them.
If you want to learn cryptography, then study it for a while before trying
to develope your own and casting aspersions on well developed algorithms.
I have no idea what your college class was, but if it was a class in
crypto, rather than physics or English, it should have taught you some of
the basics of cryptography before asking you to design even an 8 bit
algorithm.
