We are using theatobmethod to decode a string of Base64-encoded data. An alternative is to use some basic encryption algorithm like theCaesar cipher, which is fairly straightforward to implement in JavaScript. Pros: It’s more complicated for bots to get the email address, especially if you ...
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 is fun to play around with for an introduction to cryptography. While the Caesar cipher is rarely used on its own, it’s the basis for more complex substitution ciphers. In the next section, you’ll look at one of the Caesar cipher’s descendants, the Vigenère cipher....
Both of these systems, the Polybius Square and the Caesar Shift, formed the basis of many future cipher systems. In the next section, we'll look at a few of these more advanced methods of encryption. Deciphering the Language Toenciphera message means to replace the letters in the text with...
A variant of Caesar's cipher, called the Shift cipher, was introduced, where the amount of shift from the plain text to the cipher text varies, and this amount of shift can act as a key. Although this solved the immediate problem, it wasn't practical enough as the key could be guessed...

In the time of Julius Caesar (100-44 B.C.), the Romans used a similar substitution, known today as the “Caesar Shift Cipher.” Instead of reversing the alphabet, the Romans used a pre-agreed shift of the letters – only the person who knew about the agreed shift of letters could dec...
Throughout history, with the exception of the past 40 years, people have used symmetric encryption with a single key to protect information. Countless algorithms of this sort have been created (including the famousCaesar cipher), and the history of theirdevelopmentis very e...
