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?)

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)

Here's an excerpt from the lab I did in chem class today, encoded as a Caesar cipher:
