If you encrypted the word lesson using a Caesar cypher with a key of 1 which would it be?
A
mgvvqr
B
mfttpo
C
kdttph
D
kjdfkj
Explanation: 

Detailed explanation-1: -The Caesar cipher shifts all the letters in a piece of text by a certain number of places. The key for this cipher is a letter which represents the number of place for the shift. So, for example, a key D means “shift 3 places” and a key M means “shift 12 places”.

Detailed explanation-3: -To encrypt a message, enter the message in the Plaintext textbox, specify the shift, and click Encrypt. To decrypt a message, enter the message in the Ciphertext textbox, specify the shift, and click Decrypt.

Detailed explanation-4: -The following word was encrypted using a Caesar cipher with a shift of 2: ecguct. What word is it? To decrypt a message, we need to move the alphabet backwards by 2. E will become C, C become A, G become E, U become S, C become A, T become R.
