What are some good secret codes?

7 Secret Spy Codes for Kids with Printable List | Cryptography for kids

  • Morse Code. Morse code was invented in the early 1800s by Samuel Morse.
  • Pigpen Cipher.
  • Phonetic Alphabet.
  • Tap Code.
  • Letters for Numbers.
  • Substitution Ciphers.
  • American Sign Language.

Is Morse code a code or cipher?

One of the most famous examples of a cipher in regular use is Morse Code (which is not a code, but rather a cipher). Morse Code has the benefit that it can be transmitted in several ways, such as written, by sound or by light. Each letter is replaced by a series of dots and dashes as given by the key below.

What is the hardest code to decipher?

Here are 5 of the world’s hardest codes to crack

  1. Rosetta Stone. The Rosetta Stone dates back to 196 BC, but in the modern day we rediscovered it in 1799 – inscribed in three different scripts, it provided an excellent puzzle for archaeologists.
  2. Voynich manuscript.
  3. Phaistos Disc.
  4. The Shugborough Inscription.
  5. Mayan script.

Is it safe to create your own cipher?

Given even a few sentences of ciphertext is likely enough to fully recover every plaintext. The fact that you don’t know how to break it is irrelevant. It’s trivial to create a cipher that you yourself can’t break, but it’s another thing entirely to create a cipher that others can’t break.

What’s the difference between a code and a cypher?

Ciphers vs. Codes. Codes substitute arbitrary symbols—typically, letters or numbers—for the components of the original message. Ciphers use algorithms to transform a message into an apparently random string of characters.

What is a Pollux cipher?

Pollux cipher is a super-encryption system (tomogrammic) based on Morse code and replacing the dashes, dots and space by alphanumeric characters.

What is the most secret code?

These are some of history’s most famous codes.

  • The Caesar shift. Named after Julius Caesar, who used it to encode his military messages, the Caesar shift is as simple as a cipher gets.
  • Alberti’s disk.
  • The Vigenère square.
  • The Shugborough inscription.
  • The Voynich manuscript.
  • Hieroglyphs.
  • The Enigma machine.
  • Kryptos.
