Detailed explanation-1: -The Caesar Cipher is not considered a strong method of encryption since it is easy to decode. Because of this, it is incorporated just as a part of complex encryption schemes. But even this basic level of encryption was certainly valuable, especially during Caesar’s campaigns of the 1st century BC.
Detailed explanation-2: -Caesar ciphers can be found today in children’s toys such as secret decoder rings. A Caesar shift of thirteen is also performed in the ROT13 algorithm, a simple method of obfuscating text used in some Internet forums to obscure text (such as joke punchlines and story spoilers), but not used as a method of encryption.
Detailed explanation-3: -As with all single-alphabet substitution ciphers, the Caesar cipher is easily broken and in modern practice offers essentially no communications security.
Detailed explanation-4: -Transposition cipher The Caesar Cipher is one of the most basic methods for encrypting and decrypting a text. The method is named after Julius Caesar (55BC) and is a substitution cipher in which each letter of the plaintext is shifted up or down the alphabet by a fixed number of positions.
