It's just basic RSA, I kept the ciphertext as an integer here because some parts of the text got encrypted into non-printable characters. Single-letter blocks were used where the alphabet is CP-1252 ("extended ASCII").

The deciphering key is:

I just came across RSA in a number theory book and am wondering if im doing it right. Also any resources would be nice, this stuff is actually kinda interesting. Will probably move on to elliptic curve cryptography soon.
