A = C
B = D
C = E

X = Z
Y = A
Z = B
That in mind, try to figure out this simple message (Hint, it's a +4 shift and all letters are captial):

It shouldn't be too hard, since you know the encryption used. Now some might argue that is not encryption, since it is so weak, but it still is in the simplest form, encryption.
Once you get the idea, you will be able to understand other forms of encryption that are much more advanced and efficient.

You're on the right lines, but not shifting it enough. Hint: It's a phrase.
Symbols are just like any other character: They can be represented in the ASCII table. You just need to notice patterns in the encryption, and reverse it.

Not ROT13 is basically, shift 13 in any direction.
So by instance. If I type Tbbq Wbo in rot13; what does the message says?
