Making symmetric cipher encryption strong again [updated]

When students in the 2nd semester in year 1992 type on the laptop during the lecture or start talking, Professor Gerd Baron always repeated very loudly that's what's all about:

We have a universe here and 
it's all about of the number of arrangements in a finite set.

Professor Gerd Baron of Mathematics modified math lecture for computer scientists, where he claimed graph theory and combinatorics and weighted models (for traveling salesmen or ip routing) to understand better things we will need later (like equal costs => multipath).

Easiest way to scale up AES: combination & permutation

plain text ⟶ 3DES PBox → AES → 2blowfish ⟶ cipher text
cipher text ⟶ 2blowfish → AES → 3DES SBox ⟶ plain text

plain text ⟶ AES ⟶ 2blowfish ⟶ 3DES PBox (scrambled) ⟶ cipher text
cipher text ⟶ 3DES  SBox(scrambled) → 2blowfish → AES ⟶ plain text

you also can remix it per good random numbers like
3DES = 0x1
AES = 0x2
2Fish = 0x4
Serpent = 0x8

So 0xBC for encryption would mean 0xCB for decryption
plain ⟶ (3DES→AES→Serpent) ⟶ (2Fish→Serpent) ⟶ encrypted
encrypted ⟶ (Serpent→2Fish) ⟶ (Serpent→AES→3DES) ⟶ plain 

with 2 bytes strong keys (negoatiated randomized at handshake) you're quiet secure.

A simple matrix encryption algorithm by myself:

I found a simple matrix symmetric encryption algorithm, that works similiar to 3DES,
with NxN Matrix trans, after asking that question here on  math.stackexchange.com/questions/4915786/ 

R3 ➝ R3: v(3) x M(3,3) = v(3)

⎡ 1 ⎤    ⎡ 0 1 0 ⎤    ⎡ 2 ⎤ 
⎢ 2 ⎥ x  ⎢ 0 0 1 ⎥ =  ⎢ 3 ⎥  
⎣ 3 ⎦    ⎣ 1 0 0 ⎦    ⎣ 1 ⎦ 
The inverse matrix for reverse symmetric encryption would be:
⎡ 2 ⎤    ⎡ 0 0 1 ⎤    ⎡ 1 ⎤ 
⎢ 3 ⎥ x  ⎢ 1 0 0 ⎥ =  ⎢ 2 ⎥  
⎣ 1 ⎦    ⎣ 0 1 0 ⎦    ⎣ 3 ⎦

More symmetric cipher algos are now availible!

Area23.At.Mono already contained:

3DES, 2FISH, 3FISH, AES, Rijndael (same as AES), Serpent and new ZenMatrix.

The following symmetric cipher encryption / decryption algorirhms have now been added:

Camellia, Cast[56], Gost28147, Idea, RC[26], RC532, Seed, Skipjack, Tea, Tnepres, XTea.

Why I'm publishing this article?

Unfortunately, since I catched a schizoaffective disorder 2007, I have sometimes the tendency to talk loudly and am often paranoid about being wiretapped.

Existing even bigger companies, were I was employed, (I told them about my problem since 2007) meaned, that I didn't break the compliance in that case, because I can assume that we have not the GDR with Stasi here and loudly repeating fraud detection rules at home isn't a crime. Once I feeled very painful and a spoke out loudly my idea of better AES. To avoid, that only some people could get it, I wrote a simple prototype and then sended this article to old friends, who work at US companies.
