WebSep 27, 2024 · These five cryptograms are all letter substitution ciphers, at an Easy level. Each letter of the alphabet is substituted by another letter, and no letter is encrypted as itself. To start out on these puzzles, look for the most frequent letter in each cryptogram — you’ll find it’s almost always E. Single-letter words will be A or I. WebCryptography ensures confidentiality by encrypting sent messages using an algorithm with a key only known to the sender and recipient. A common example of this is the messaging …
