WebApr 3, 2015 · (Definition) The Letter-to-Number Cipher (or Number-to-Letter Cipher or numbered alphabet) consists in replacing each letter by its position in the alphabet, for example A=1, B=2, Z=26, hence its over name A1Z26. How to encrypt using Letter-to-Number/A1Z26 cipher? A1Z26 encryption requires to count the positions/ranks of letters … WebSep 27, 2024 · Cryptography 101: Basic solving techniques for substitution ciphers. It doesn’t matter whether a cryptogram presents you with letters, numbers, arcane symbols, lines and dots, or weird alien squiggles — if you’re asked to replace each letter in the alphabet with another symbol, you’re dealing with a simple substitution cipher.

Classical ciphers are often divided into transposition ciphers and substitution ciphers, but there are also concealment ciphers. (Main article: Substitution cipher) In a substitution cipher, letters (or groups of letters) are systematically replaced throughout the message for other letters (or groups of letters).
