Alphabet cipher tool

So G is decrypted with D. So A is decrypted X. A message encoded with the Caesar cipher has a shift in its frequency analysis diagram equal to the selected shift and a coincidence index similar to the one of the plain text.

Any reference to Caesar, emperor of Rome, or more generally to antiquity and the Roman Empire are clues. Caesar cipher is best known with a shift of 3, all other shifts are possible. Some shifts are known with other cipher names. Caesar cipher is applicable only to letters of the alphabet.

There are, however, several solutions to crypt numbers:. Caesar Caius Iulius Caesar used this technique for some correspondences, especially military, for example with Cicerone shift of 3. Caesar cipher is also known as Shift Cipher. This shifting property can be hidden in the name of Caesar variants, eg.

Any 2-letter code that can give an association between a crypted char and the plain one see gramograms. ROT5 code for digits, the shift is 5 and reversible. Write the letter with rank R2 in the alphabet. The code was named after Julius Caesar who was born in BCE the first man which has testimonies like Suetonius proving that he used this type of substitution to protect his military communications. The exact date of creation and its real author are unknown. With no key needed to translate it, it is easily broken with just a pen and paper.

Rather than using a word in its normal form, and at full power, they will encrypt it to change the numerical value of it which then reduces its impact. Atbash in its regular form only encrypts the letters A-Z, leaving numbers and punctuation as plain text. Variant forms of the cipher do exist which include numbers and the most common punctuation symbols. As the first cipher used, we can forgive Atbash for its simplicity.

It was invented in days gone by, when far less people were literate and there were no computers who could flip the text with ease. Code-breaking is not only fun, but also a very good exercise for your brain and cognitive skills. Atbash Cipher Tool You must enter the message.

Instructions You can decode decrypt or encode encrypt your message with your key. Settings Language : The language determines the letters and statistics used for decoding, encoding and auto solving. Max Results : This is the maximum number of results you will get from auto solving.

Spacing Mode : This is about the spaces word breaks in the text. It is stronger than an ordinary Playfair cipher, but still easier to use than the four-square cipher. Depending on the orientation of the squares, horizontal or vertical, the cipher behaves slightly different. It is a digraph cipher, where each pair of letters in the ciphertext depends on a pair of letters in the plaintext.

It uses four 5x5 squares to translate each digraph. Base64 is another favorite among puzzle makers. Not seldom will the contents need further decoding. Base64 is easy to recognize. Morse Code is a highly reliable communications method, that can be transmitted in many ways, even during difficult and noisy environments. That makes it especially useful for puzzle games, where it is sometimes not fully obvious that a code is a Morse Code.

Morse Code can be recognized by the typical pattern: small groups of short and long signals. These signals could be actual tones, or other means such as lines, colors, letters or symbols. They can also represent the output of Hash functions or modern crypto algorithms like RSA, AES, etc, even if they usually are presented in hexadecimal or binary format. It was invented by Lieutenant Fritz Nebel and is a fractionating transposition cipher which combines a Polybius square with a columnar transposition.

Secret messages can be hidden within plaintext, or something that looks like plaintext, using steganography techniques. Some of the most common steganigraphy techniques are the so called NULL cipher and the baconian cipher. Other possibilities are that the text is a riddle or using anagrams.
