RSA Encryption and Decryption

Try RSA with Toy Key

1. Using the key pair [ (, ); (, ) ]

2. Encrypt the message T=20. What is the cyphertext (C = T³⁷ mod 77)?

   Use this tool to computer powers of T mod 77.

   × mod 77

3. Take your value C and perform the decryption: (C¹³ mod 77). Do you get 20 back?
