In this question, we have to decrypt the cipher text which is given to be p -e -g -x -a, h -w -d -l -t -g -g -h, which has been encrypted using caesar cipher.
00:15
So the cipher which is uses caesar cipher and the key is given to be 15.
00:21
Now we have to decipher this text.
00:24
So first of all, we will write all the letters.
00:27
A, b, c, d, e, f, g, g, h, i, j, k, l, m, n, o, p, q, r, s, u, v, w, w, x, y, z.
00:45
And since the key is given to be 15, we will shift these to 15 units.
00:50
So 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 13, 13, 13, 13, 13, 13, 13, 13, 14, 15.
00:59
Since 15 is here, we will shift our letters, 15 units.
01:05
So we will start from here...
