The key is how many spots in the alphabet you must move to find the original letter or set of letters in a word to decrypt the message. The key was three in this version of Caesar cipher, in which case you would substitute the letter D for letter A, H for E, and so on. ...
The Caesar cipher was once state-of-the-art in keeping messages secret by substituting one letter for another. It is now reduced to a cryptogram game that my 96-year-old grandmother tackles daily. We’ve come a long way since Caesar ciphers were state-of-the-art, but ...
When encrypted data is intercepted by an unauthorized entity, the intruder has to guess which cipher was used to encrypt the data and what key is required to decrypt the data. The time and difficulty of guessing this information is what makes encryption such a valuable security tool. The more...
To ensure secure file access, data encryption has evolved significantly from ancient techniques like the Caesar Cipher to sophisticated algorithms that are in use today. Modern encryption makes use of complex algorithms that shuffle file contents, with decryption relying on a provided key. ...

One of the ways it’s different gets around a somewhat obvious problem with the Caesar cipher: you have to somehow let your recipient know the key used to encode the encrypted message. PKI gets its name because each participant in a secured communications channel has two keys. There...
