#### A1Z26 cipher - decoding tool

Tool to decode A1Z26 cipher. The A1Z26 cipher got its name from the way it works: A=1, B=2, ..., Z=26. It is simplest possible letters to numbers translation. Although the cipher is intended for the English alphabet, it can easily be used for other languages as well.

#### Anagrammer and word finder

Tool to solve and find anagrams. An anagram is a word, phrase or sentence that can be made by rearranging a collection of letters. Anagrams are used by many code-breaking puzzles as well as cryptic crosswords and games like Scrabble. A person who enjoys solving anagrams is called an anagrammer.

#### Ascii table, ASCII character codes hex, decimal, binary

Ascii table for all 7-bit printable characters. ASCII stands for American Standard Code for Information Interchange. It is a standard for character encoding in digital communications. This table contains the printable characters(letters, digits, punctuation characters and miscellaneous symbols).

#### Atbash cipher decoder, solver and encoder

Tool to decrypt Atbash cipher. The Atbash cipher is a simple substitution cipher, where each letters is replaced by its equivalent in a reverse alphabet. Atbash was originally used for encrypting the Hebrew alphabet, but the method can be used with any alphabet.

#### Barcode scanner and translator

#### Base64 decoder and encoder online

Base64 decoding and encoding tool. Base64 is an worldwide standard encoding to represent binary data in an ASCII string. Each Base64 character represents exactly 6 bits of data.Therefore, four Base64 characters represent three bytes of data.

#### Baudot code, Baudot-Murray code - decoder and encoder

Baudot code decoding tool. The original Baudot code was invented by Émelie Baudot in 1870. It was a 5-bit code that became known as the International Telegraph Alphabet No 1(ITA1). In 1901, the code was improved by Donald Murray. Murray designed the code to minimize the wear on the machinery.

#### Beaufort cipher decoder and encoder

Tool to decrypt Beaufort ciphers. The Beaufort cipher is named after Sir Francis Beaufort. It is similar to the Vigenère, but the encryption and decryption is reciprocal (the encryption and decryption algorithms are the same). The Beaufort cipher is a polyalphabetic cipher.

#### Braille alphabet - decoder, translator

Tool to translate the Braille alphabet. Braille is a tactile writing system for visually impaired people. It was created by Lous Braille, a Frenchman who lost his sight because of a childhood accident.

#### Caesar cipher decoder, solver and encoder

Tool to decrypt Caesar cipher. The Caesar cipher is a very basic substitution cipher. It is also known as a shift cipher or Caesar shift. The cipher is named after Julius Caesar, who used it in his private communications.

#### Dancing men cipher - decoder, translator

Tool to decrypt Dancing Men cipher. Dancing Men cipher was invented by Sir Arthur Conan Doyle and appeared in his story The Adventure of the Dancing Men. In this story, Sherlock Holmes discovers that the dancing figures is a secret cipher and cracks the code.

#### Encodings code-breaking resources

Overview of encodings and decoding tools for solving escape room games, geocaching mystery caches, CTFs and more.

#### Encryptions and ciphers code-breaking resources

Overview of encryption methods and ciphers for solving logic puzzles, geocaching mystery caches, CTFs and more.

#### Gronsfeld cipher decoder and encoder

Tool to decrypt Gronsfeld ciphers. The Gronsfeld cipher, also called Bronckhorst cipher, was invented by José de Bronckhorst (earl of Gronsfeld) in 1744. It is similar to the Vigenère cipher, but uses digits instead of letters in the key.

#### Hexahue alphabet - decoder, translator

Tool to decrypt Hexahue code. Hexahue, and variants of it, are used occasionally in geocaching mystery caches, CTFs and logic puzzles. Look specifically for the color combinations to recognize it.

#### Code-Breaking, Cipher and Logic Puzzle solving tools

Free tools for code-breaking, solving ciphers and logic puzzles, room escape games, CTFs, Cicada 3301 and more.

#### International Code of Signals maritime flags

International Code of Signals maritime flags were first drafted by the British Board of Trade in 1855 and adopted as a world-wide standard on 1 January 1901. It is used for communications with ships.

#### Letters to numbers - numbers to letters - converter

Tool to convert letters to numbers (or numbers to letters). Numbering the letters so A=1, B=2, etc is the simplest way of converting them to numbers. This is called the A1Z26 cipher or simply letters to numbers. However, the numbering can also start somewhere else than at 1.

#### Morse code - translator, decoder, alphabet

Tool to translate Morse code. Morse code is named after Samuel Morse, one of the inventors of the telegraph. Morse code can be transmitted used sounds or light, making it useful at sea. It is a highly reliable communications method even during difficult environments.

#### Number systems code-breaking resources

Overview of number systems commonly used in logic puzzles, geocaching mystery caches, etc.

#### Masonic/pigpen cipher - decoder, translator

Tool to decrypt pigpen cipher. Pigpen cipher is a monoalphabetic substitution cipher, where the letters are replaced by geometric symbols. It is also known as masonic cipher, Freemason's ciper, Napoleon cipher and tic-tac-toe cipher.

#### Playfair cipher decoder and encoder

Tool to decrypt Playfair ciphers. The Playfair cipher was invented in 1854 by Charles Wheatstone, but named after lord Playfair who heavily promoted the use of the cipher. It is a polygraphic substitution cipher, which encrypts pair of letters instead of single letters.

#### QR Code scanner and translator

QR Code scanner and translation tool. The QR Code was invented by Japanese company Denso Wave Inc in 1994. It can store data efficiently and also handle scanning errors due to the Reed - Solomon error correction. The QR Code is one of the most popular two-dimensional bar - codes.

#### Rail fence cipher decoder and encoder

Tool to decode rail fence ciphers. The rail fence cipher is a simple transposition cipher. It is also known as a zigzag cipher. In a rail fence cipher, the plaintext letters are written diagonally in a up-down pattern from left to right.

#### ROT13 cipher decoder, solver and encoder

Tool to decode ROT13. ROT is a basic substitution cipher, where each letter is replaced by another letter 13 steps down the alphabet. It is a special case of the Caesar cipher. Since there are 26 letters (2 x 13) in the English alphabet, the shift direction does not matter.

#### Semaphore flags - decoder, translator

Tool to translate flag semaphores. Semaphore flags is a telegraphy system to communicate at a distance by means of visual signals. It can use hand-held flags, rods, disks, paddles, or occasionally bare or gloved hands.

#### Steganography code-breaking resources

Overview of steganographic tools used by logic puzzles, geocaching mystery caches, or even the Cicada 3301 challenges.

#### Text and word tools code-breaking resources

Overview of text tools for helping solving CTFs, logic puzzles, geocaching mystery caches and more.

#### Unicode utf-8 decoder online

Unicode is the worldwide standard for encoding and representing text in most of the world's writing languages, maintained by the Unicode Consortium. Currently Unicode has over 137000 different characters, covering both modern and historical languages as well as symbols and emojis.

#### Upside down text, flip text [uʍop ǝpᴉsdn]

This free online tool turns your text into upside down text that can be pasted into Facebook, Twitter, blogs, forums and more. The tool uses the Unicode alphabet to play this visual trick. The upside down text can either be presented as rotated or mirrored.

#### Variant Beaufort cipher decoder and encoder

Tool to decrypt variant Beaufort ciphers. In the variant Beaufort cipher, encryption is performed like decryption in the Vigenère cipher, and decryption is performed like encryption in the Vigenère cipher, so it is in practice a "variant Vigenère cipher".

#### Vigenère cipher decoder and encoder

Tool to decode Vigenère ciphers. The Vigenère cipher is named after Blaise de Vigenère, but it probably was invented by Giovan Battista Bellaso around 1553. The cipher is easy to understand and use, but it was considered unbreakable for three centuries.
