For the purposes of cryptograms it is customary to treat n and ñ as distinct letters, but a and á are the same letter. Likewise for e and é, and i

and í. In other words, all the accent marks get amputated when working with cryptograms. Also, while some older Spanish dictionaries consider

ch, ll, and rr, to be their own letters—this has fallen out of modern usage. Accordingly, “burro” is considered as five letters: “b-u-r-r-o” and not as

four letters “b-u-rr-o.”

Famous Phrases Gettysburg address

POLITICAL BANDS WHICH HAVE CONNECTED THEM WITH ANOTHER AND TO ASSUME AMONG THE POWERS OF THE

EARTH, THE SEPARATE AND EQUAL STATION TO WHICH THE LAWS OF NATURE AND OF NATURE'S GOD ENTITLE

THEM, A DECENT RESPECT TO THE OPINIONS OF MANKIND REQUIRES THAT THEY SHOULD DECLARE THE CAUSES

WHICH IMPEL THEM TO THE SEPARATION.

17) [450 points] Ella and Isabella are accountants for a very large bank, and have started a friendship. They communicate via email, because

they live thousands of miles apart. Isabella gets curious and asks Ella the year that they were born. Ella doesn’t mind telling Isabella, but they

know that the bank monitors all employee emails, and is afraid of being the victim of age discrimination. Therefore, Isabella suggests that they

use RSA, and they provides their public key: (201277, 101639). Ella replies with the ciphertext 174071. Isabella’s private key is 92999. In what

year was Ella born?
