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. WebIt is a 5 letter text. To break the ciphertext by brute force, you need to try all possibilities of keys and conduct computation for (26 x 26 x 26 x 26 x 26) = 26 5 = 11881376 times. That’s for a message with 5 alphabets. Thus, for a longer message, the computation grows exponentially with every additional alphabet.
