what is the difference between propaganda and hoax?

I was looking for definitions of propaganda and hoax. The problem is that people in the internet are trying to post their own definitions without a clarification.

At the end I chose these following definitions:

Propaganda: is a fabricated story spread to manipulate readers and to harm the interest of a particular party.

Hoax: is similar to propaganda but the main aim of the author is not to manipulate readers’ opinions but to convince them of the validity of a paranoia-fueled story.

Do you think that they are correct/clear?
