Q: decrypt the message

MPFOAIMSTTAITLEYRO

there is no any other hint.

That is why I dont know how to decrypt it..

please figure it out with showing your method.

Answer 1

we will do with the help of cryptography.

The given message in the question is cipher text(after transformation to a secret form a message is called cipher text) .we nee to decrypt it .The process of changing from cipher text back to plain text (the information to be concealed is plain text) is called decrypting or deciphering.

We will use the method Caesar Cipher,

One of the earliest cryptographic system was used by Roman emperor Julius Caesar around 50 BC.Caesar wrote to Marcus Cicero using a rudimentary substitution cipher in which each letter of the alphabet is replaced by the letter that occurs three places down the alphabet,with the last three letters cycled back to the first three letters.If we write the cipher text equivalent underneath the plaintext letter, the substitution alphabet for Caesar Cipher is given by ,

Plain text : A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

Cipher text : D E F G H I J K L M N O P Q R S T U V W X Y Z A B C

here the given cipher text is,

we are going to decrypt it with the help of above mentioned cipher text and plain text
