Question

Decrypt the following message that is encrypted with a basic alphabetic shift cipher. What is the shift?

OTPAYZOIK GTECNKXK OY G ZNXKGZ ZU PAYZOIK KBKXECNKXK. - SGXZOT RAZNKX QOTM PX.

Answer 1

Shift Cipher : The shift cipher encryption uses an alphabet and shifts the position of its letters.

For example : letter A stands in first position in alphabetical order. If we want to decrypt Letter A by applying Shift cipher of 3 to letter A, the result will be letter X. I.e. A is shifted by 3 letters which results in letter X.

Encrypted message : OTPAYZOIK GTECNKXK OY G ZNXKGZ ZU PAYZOIK KBKXECNKXK.

By applying Shift cipher, we get

The shift applied in above message if of 6 shifts.
