title: rsa - calculating plaintext from ciphertext
body: <p>I was solving a crypto question but now I am stuck for a long time. 
  I have to calculate plaintext, when I am given ciphertext, n, and e only. How to do so?
  I don't have the totient otherwise it would have become easy.</p>
  
  <p>ciphertext: <code>107524013451079348539944510756143604203925717262185033799328445011792760545528944993719783392542163428637172323512252624567111110666168664743115203791510985709942366609626436995887781674651272233566303814979677507101168587739375699009734588985482369702634499544891509228440194615376339573685285125730286623323</code> </p>
