‣ The Caesar Cipher, also known as a shift cipher invented by Julius Caesar, is one of the oldest and simplest forms of encrypting a message.
It is a type of substitution cipher where each letter in the original message (which in cryptography is called the plaintext) is replaced with a letter corresponding to a certain number of letters shifted up or down in the alphabet. For example with a shift of 1, A would be replaced by B, B would become C, and so on.
Examples:
↳ Text: AVEFELLOWWELLMET
Shift: 1
Cipher: BWFGFMMPXXFMMNFU
↳ Text: AVEFELLOWWELLMET
Shift: 2
Cipher: CXGHGNNQYYGNNOGV
↳ Text: AVEFELLOWWELLMET
Shift: 3
Cipher: DYHIHOORZZHOOPHW
↳ Text: AVEFELLOWWELLMET
Shift: 4
Cipher: EZIJIPPSAAIPPQIX
↳ Text: AVEFELLOWWELLMET
Shift: 10
Cipher: KFOPOVVYGGOVVWOD
↳ Text: AVEFELLOWWELLMET
Shift: 13
Cipher: NIRSRYYBJJRYYZRG
↳ Text: AVEFELLOWWELLMET
Shift: 20
Cipher: UPYZYFFIQQYFFGYN
↳ Text : ABCDEFGHIJKLMNO
Shift: 23
Cipher: XYZABCDEFGHIJKL
↳ Text: AVEFELLOWWELLMET
Shift: 25
Cipher: ZUDEDKKNVVDKKLDS
To decipher a message, you just need to offset the key shifted up in the plaintext on each letter of the alphabet. The Rot Cipher is almost the same as the Caesar Cipher.
