comment Why are primes important for encryption
The statement you made "It is very easy, even trivial, to find a factor of it, but not all factors" seems to be incorrect, or at least misleading. Since there's only two factors, either of which would be difficult to find.

Just write a loop, try to decrypt, if it decrypted successfully, you have the correct key.

This property of hashes' is called the "Avalanche effect": en.wikipedia.org/wiki/Avalanche_effect

I am using the default values provided by the .NET implementation, which I believe is CBC with PKCS7 padding.

Thank you, your last line "Knowing something about the plaintext does not help the adversary." was what I was looking for.
