I have been fond of cryptography since childhood.
I was collecting various methods of secret writing, interesting from my point of view, and coming up with my own.
I had a special notebook in which about 100 ways to encrypt a message were described. I don鈥檛 know why it was interesting to me.

I bring to your attention the encryption. It is made using a simple but witty cipher as it seems to me, which I came up when I was maybe 12 years old.

If you manage to understand the meaning of what has been written, then hint in the comment below that you have found the answer :)

If you need a hint, I'll give it :)

Looks like I underestimated you :)
But the hint is very clear, rather a spoiler.

It's far too easy.

If you had written it as

ITHWA REERR HNEAY ETVBU ENFRF HHEUO .... AONTH EBSTO

you would have replicated a classical form of a transposition cipher.

That said, not bad for a 12 yo to come up with it independently.

Now solve this one. I will give you some clues. It is a simple substitution cipher. The message was sent to a unit engaged in Napoleon's Egyptian campaign in which one of the locals, a real PITA to the commanding officers by and large, had shown great bravery in the aid of the French army but in doing so had lost almost all his clothes and came in to the camp shivering with cold.

ABCD EFGHIJ K.L.M NOPQ, RST UV W.X.Y.Z

That is a famous one Jim Gillogly and I solved some years back. If you really can't do it yourself you may be able to find our solution on the net.

My apologies.

Edited to blank out the text so that those who have not yet seen the solution can try for themselves.

Here's one I solved a month ago. The prize was a free book just published by the author of the cryptogram

Clue: the solution is a single ten-letter English word.

I wonder what you think about Voynich manuscript. Surely you were interested in this.

This is a beautiful task, but rather non-trivial :) I found the answer on the net, I confess.

I really don't know what to make of it.

My front-runner hypotheses are that it is a clever fake with little or no underlying meaning ,or a text in an invented language.

The relatively common presence of tripled glyphs is most unusual in natural languages. Some examples in English are wallless, goddessship and headmistressship but there are very few others.

In German, where we have lots of compound nouns, there are still few of tripled glyphs. Since our othography changed ("neue deutsche Rechtschreibung") we got even more of them, but still few.

IIRC, the Voynich Manuscript contains three-letter-words that only consist of one distinct letter. This would be unheard of in German. For some languages, I think we can rule this out, too. But I'm not sure if this is true in general.
