1. Reverse the alphabet to create a basic cipher alphabet. Substitution ciphers work by creating a disordered alphabet, allowing you to substitute letters for other letters. For a straightforward substitution cipher, simply use the alphabet backwards, so that “a” becomes “z,” “b” becomes “y,” “c” becomes “x,” and so on. [1]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 essentially a standard … Four-square cipher. The four-square cipher is a manual symmetric encryption technique. [1] It was invented by the French cryptographer Felix Delastelle . The technique encrypts pairs of letters ( digraphs ), and thus falls into a category of ciphers known as polygraphic substitution ciphers. This adds significant strength to the encryption when ...

Encoding each letter by its numerical position in the alphabet a = 1, b=2 and so on, the shift cipher is obtained by addition modulo 26. So a shift by 3 sends 7 to 7+3=10, which corresponds to mapping g to J. At the end of the alphabet we have. Learn how to encrypt and decrypt messages using a random order of ciphertext letters created by a keyword or keyphrase. The Mixed Alphabet Cipher is a Monoalphabetic Substitution Cipher that uses a keyword or keyphrase to generate a random ciphertext alphabet. ROT13 is a shift cipher, that’s a simple kind of encryption where the ciphertext is created by taking the plain text message and shifting (moving forward in the alphabet) by a certain number of letters. The name is a shorthand version of ‘rotation 13’. It’s also a type of substitution cipher, because one letter is substituted for another.The Vigenère cipher is a polyalphabetic substitution cipher that was invented by Giovan Battista Bellaso in 1553. It is named after Blaise de Vigenère, who introduced the concept of using a series of different Caesar ciphers, with different shift values, to encode text in 16th century France. The Vigenère cipher uses a 26-letter alphabet (A-Z).Monoalphabetic cipher is a substitution cipher in which for a given key, the cipher alphabet for each plain alphabet is fixed throughout the encryption process. For example, if ‘A’ is encrypted as ‘D’, for any number of occurrence in that plaintext, ‘A’ will always get encrypted to ‘D’.The Author cipher (from Gravity Falls) has its own alphabet of 26 symbols and their correspondance with the classic letters of the Latin alphabet. The Author decryption consists in replacing these symbols to get the original plain message. Example: is …The Standard Galactic alphabet (also abbreviated SGA) is a series of 26 symbols replacing the 26 letters of the classic Latin alphabet. The writing of a text in English is satisfied with a replacement character by character. Example: STANDARD s'écrit. The numbers 0-9 are not intended to be translated into the Standard Galactic Alphabet.The Caesar Cipher is based on the simple principle of shifting each letter of the original text a fixed number of positions in the alphabet. Mathematically, this can be expressed as: E n ( x) = ( x + n) mod 26. where E n ( x) is the encrypted letter, x is the alphabetical index of the letter, and n is the magnitude of the shift.
