However, the Greeks weren't alone in developing primitive cryptography methods. The Romans followed suit by introducing what came to be known as "Caesar's cipher," a substitution cipher that involved substituting a letter for another letter shifted further down the alphabet. For example, if the ...
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. write the letter one forward, change it to the one in front and so each letter, dep...
Encryption can be applied to protect data but relies upon the rest of the security stack to protect the encryption keys, computers, and network equipment used to encrypt, decrypt, and send encryption-protected data. Organizations should apply encryption solutions that enhance and complement existing ...
In symmetric-key encryption, each computer has a secret key (code) that it can use to encrypt a packet of information before it is sent over the network to another computer. Symmetric-key requires that you know which computers will be talking to each other so you can install the key on ...
The best way to understand simple cryptography is to look at one of its earliest forms, the Caesar cipher. Julius Caesar used it to encrypt confidential correspondence between him and his officials. Caesar encrypted his messages by changing the order of the alphabetical letters. In order to decry...

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 ...
Like caesar_cipher(), vigenere_cipher() iterates over each letter of the input text to encrypt or decrypt it: Python for i, char in enumerate(text): current_key = key[i % len(key)] In the above code, you can see the function’s first use of the modulo operator: Python curren...
