Affine Cypher Define an encryption function f as below. f(p) = (3p + 17) mod 26 Use this function to encrypt the message "BEWARE OF ROGUE MANDRILLS" Find the decryption function and use it to decrypt the message WMD APTXQDWD ADTKDQRAHT RQD HE WH LHZ" (Include both the decryption function and the decrypted message in your report.] An affine cipher, in general, uses a function of the form f(p) = (ap + b) mod 26 with gcd(a, 26) = 1. The message below was encrypted with some affine cypher. Can you crack the code and find the function that encrypted it? [Include both the encryption function and the decrypted message in your report.] "SRVYLOYBV VNY BELYRVNYQYQ TYHSFYLU VWRSINV" RSA Cryptosystem Suppose an RSA-style cryptosystem is set up with public key (3247, 13) and private key (3247, 1637). Use the public key to encrypt the message "NUECES". Use the private key to decrypt the message 1014 2914 858. Alice, Bob, Chanique, and Daisuke all have the following public keys.
