    Caesar cipher. The action of a Caesar cipher is to replace each plaintext letter with a different one a fixed number of places down the alphabet. The cipher illustrated here uses a left shift of 3, so that (for example) each occurrence of E in the plaintext becomes B in the ciphertext. In cryptography, a Caesar cipher, also known as Caesar's ...

    Affine cipher. The affine cipher is a type of monoalphabetic substitution cipher, where each letter in an alphabet is mapped to its numeric equivalent, encrypted using a simple mathematical function, and converted back to a letter. The formula used means that each letter encrypts to one other letter, and back again, meaning the cipher is ...

  7. Substitution cipher - Wikipedia

    en.wikipedia.org/wiki/Substitution_cipher

    t. e. In cryptography, a substitution cipher is a method of encrypting in which units of plaintext are replaced with the ciphertext, in a defined manner, with the help of a key; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth. The receiver deciphers the text by ...

    Aztec was pictographic and ideographic proto-writing, augmented by phonetic rebuses. It also contained syllabic signs and logograms. There was no alphabet, but puns also contributed to recording sounds of the Aztec language. While some scholars have understood the system not to be considered a complete writing system, this is disputed by others.
