Encode the following word (one letter at a time) using RSA with e = 5 and n = 101.

You're right.
Isn't n supposed to be the product of two primes though?
Also, do you want me to use A=0, B=1, C=2, D=3, ..., Z=25 or convert the letters to ASCII code?

Yeah my bad I just chose a random n. n=102 should work? (51*2) and yeah just convert the letters directly (A=0, B=1, etc).

49 17 24 24 18 (Interestingly, 17 and 18 encode to themselves?)
or I guess XRYYS

51 is not prime.

Riptide has left the server (UTF please ask a question so I can bury this mess) (also I got 4 for E not 24? but then again I clearly don't know RSA or math)
