If we want to decrypt this message here using the caesar cipher, well, if we have just the original alphabet, what the caesar cipher does with this p plus 3, it shifts all the letters 3 to the right.
00:25
So like a would go to 1, 2, 3d, b would go to 1, 2, 3e, and so on and so forth.
00:34
So let's just go ahead and do that really quickly.
00:36
So we already said a gets translated to 1, 2, 3d, and then we could just write down the alphabet as we normally would.
00:44
So it would go d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, w, x, y, z.
01:02
And then we restart.
01:03
Then go to a, b, c.
01:07
Okay.
01:09
So what we now need to do is, well, we have the ciphered message here.
01:15
So this is the cipher.
01:18
And to figure out the original, we just need to look down at the cipher and see what letter matches up with it.
01:26
So w is here, so that matches up with t.
01:32
So w gets translated to t.
01:35
I'll just cross this off, so i know where we are.
01:39
So we need to come down here...
