First we take the whole alphabet, alp = 'a, b, c, d, ...), etc., then, we get the user input, then we find these letters in alp, and +1 should go to each letter , i.e.
Modern encryption technology uses more sophisticated algorithms and larger key sizes to conceal encrypted data better. The larger the key size, the more possible combinations a brute force attack would have to run to decrypt the ciphertext successfully. ...
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 ...
Encryption algorithms use math to lock the data, but computers can be used to attack that math with brute force computing power. Weak passwords and short key lengths often allow quick results for brute force attacks that attempt to methodically guess the key to decrypt the data. ...
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...
