Would you like to have a special way of communicating that only you and your kids understand?The Shifted Alphabet Code is very very easy to do. Begin by writing down the alphabet in order on a piece of paper or use the one below. Now pick a number between 1 and Got it?
I picked the number 3. Then, since the next letter is I, find the I and count forward to get the letter L. Keep going through the whole message like that. Uh oh Just leave that exactly the way it is. Uh oh again! I can't count forward 3 letters, because there aren't enough letters in the alphabet! That's okay So Y becomes B! Get the idea? Now you can try the Encoder at the top of the page. Is this code difficult to decode? Because, in order to decode it, you need to know how many letters the message was shifted in the first place!
No, they don't. Because it's too easy to decode.
But it's still fun to play with. The Problem Site. Quote Puzzler. Tile Puzzler. Loading profile Logged in as:.

Imagine being able to write notes to each other that no one else can read! We started out with mouse… I mean morse code because my 7 year old had read about it in a Horrible HIstories book affiliate link.
Morse code uses dots, dashes and spaces to represent letters numbers and symbols. You can write morse code, or send it with flashes of light or sounds. Once a prisoner of war even sent a message in morse code by blinking his eyes! We even had a go at using a flashlight to send morse code but that was pretty tricky! You can download the free printable Morse code sheet here. The Pigpen cipher is a really old code that is really fun to write. I left my boys a secret message in pigpen for them to decode when they woke up one morning!
6 Amazing Secret Codes Your Kids Will Really Enjoy
After that first message I suddenly started to get little notes written in Pigpen, so I had to keep my decoder sheet handy so I could work out what they said! You can download the free printable pigpen secret code sheet here. Now that we had the hang of this cool secret code thing, it was time for us to try making our own! We learned that it is important to make the symbols and drawings we used to represent each letter quite simple, and easy to reproduce accurately.
If you make them too complicated it will be impossible to write a coded message that someone else can decipher! I made up a simple sheet with letters, numbers a couple of punctuation marks and a few blank spaces so we could create as many new secret codes as we wanted! This printable is an A4 sized pdf file, you will need a pdf reader such as adobe acrobat to open it. Please remember that the printables at picklebums.

The empowering concept here is the fact that you can change the text selection color and background-color in modern browsers. Then we have a little UI system for marking individual letters.
All that does is toggle a specific class name on those spans. Non-marked spans have a color and background-color of white, which means they effectively disappear when selected. The marked spans change color. So when the whole block is highlighted, the secretly marked letters reveal themselves. Like about everything fancy we do around here, it uses jQuery. A way finally dawned on me…. When that fires, set some data to indicate that the mouse is currently down.
At the moment this only works for turning on cells not mass-erasingbut it could probably be tweaked to do that too. I set the text selection color the standard way, for both rendering engines. Firefox respects it, Opera respects it, but neither of the big WebKit browsers will. Frontend Masters is the best place to get it. As for the WebKit selection background, background:transparent; should work fine. It does for me anyway. I just did something very similar to your toggle a few weeks ago for a dwarf fortress thing.
I can provide some code if you want. I literally squealed with joy.During these challenging times, we guarantee we will work tirelessly to support you.

We will get through this together. Updated: March 9, References. Codes are a way of altering a message so the original meaning is hidden. Generally, this requires a code book or word. Ciphers are processes that are applied to a message to hide or encipher information.
These process are reversed to translate or decipher the message. Note: Though this code can be easily solved, but it can be useful if you think someone is trying to peek at your message. Tip: To strengthen your encoding ability, you may want to invite your friends to join an amateur code making group. Pass messages to improve your skills. Tip: Different editions of books might use different page numbers.
To ensure the right book is used as a key, include publication information, like edition, year published, and so on with your book key.
TIp: Amateur cryptography clubs are popular online. Many of these are free and offer primers in the basics of modern ciphering. Note: Transposition ciphers generally treat messages or the formation of letters visually.
The image of the message is transformed to hide its meaning. To create a secret code or cipher, start by writing the letters A through M in one row and the letters N through Z in another row underneath.

Do this each time until you see intelligible words. Then, with your left mouse button held down, drag across all the text to highlight it, press Ctrl C, paste into Notepad and print. A letter offset code is very straightforward. Imagine that you have the alphabet printed out twice, as two lines on a long strip of paper. If you cut the two apart and push the bottom piece of paper a little to the left, the A on the top line will be directly above the B on the second line.
Now suppose that you write the letter from the bottom line each time you mean a letter on the top line. Obviously, there are 25 different Offset Letter Codes. Even though they are simple they can be very puzzling indeed. Without a decoding program such as this one, the code solver must use some ingenuity.
Always look for single letter words. There are only two in every-day English, "I" and "a". Look for three letter words that are used often. They are quite likely to be "the" or "and". Also notice which letters are used most frequently.
The letter "e" occurs more often in English than any other letter, and more words begin with "s" than with any other. All words must have vowels—but remember that "y" can be a vowel too. It may take some time, but you can always crack an offset code if you stick at it.
One very easy way to make up a code is to draw three copies of the grid that we use to play "Noughts and Crosses" or "Tic Tac Toe". Leave the first grid blank, put circles or dots into the second, and put crosses into the third. Write the letters of the alphabet at random in the three grids. You can then write words by drawing the shapes that are associated with the individual letters, like this:.
You can make variations of this idea. Instead of putting symbols in the grids, you could draw one grid with single lines, one with double lines, and one with wavy lines. Book codes are much harder to crack, because there is no logical order in the encoded material. Each person—the one sending the message and the one reading it—has a copy of the same book.
