Question

Given that the Caesar's cipher was used, find the plaintext that corresponds to the following ciphertext: VSRQJHEREVTXDUHSDQWV Find the plaintext and the key, given the ciphertext CSYEVIXIVQMREXIH The weak ciphers used during the election of 1879 employed a fixed permutation of the words for a given let sentence. To see that this is weak, find the permutation of (1, 2, 3, 4,...., 10) that was used to produce the scramb sentences below, where "San Francisco" is treated as a single word. Note that the same permutation was used for three sentences.

Explanation / Answer

PLEASE POST AS SEPARATE QUESTIONS (WILL DO 1st and 2nd)

1) Since this is Caesar's cipher. let us try to solve by using shift key <=3

v   s   r   q   j   h   e   r   e   v   t   x   d   u   h   s   d   q   w   v
u   r   q   p   i   g   d   q   d   u   s   w   c   t   g   r   c   p   v   u
t   q   p   o   h   f   c   p   c   t   r   v   b   s   f   q   b   o   u   t
s   p   o   n   g   e   b   o   b   s   q   u   a   r   e   p   a   n   t   s

at shift key = 3

plaintext is: s   p   o   n   g   e   b   o   b   s   q   u   a   r   e   p   a   n   t   s

2) Since this is Caesar's cipher. let us try to solve by using shift key <=4

c   s   y   e   v   i   x   i   v   q   m   r   e   x   i   h                                      
b   r   x   d   u   h   w   h   u   p   l   q   d   w   h   g                                      
a   q   w   c   t   g   v   g   t   o   k   p   c   v   g   f                                      
z   p   v   b   s   f   u   f   s   n   j   o   b   u   f   e                                      
y   o   u   a   r   e   t   e   r   m   i   n   a   t   e   d                      

So the key is +4

plaintext is: y   o   u   a   r   e   t   e   r   m   i   n   a   t   e   d
