The Answer

Encryption type:
 Caesar cipher or Additive cipher

 Our Slogan  is “we are leading the future”

How we solve it? Caesar cipher is to think of cycling the position of the letters. In a Caesar cipher with a shift of 20, c becomes w, and when reaching the end of the alphabet it cycles around, so k becomes e and so on.
