Not true at all.  The RSA algorithm is patented and can't be used without  
paying royalties to the patent holders.  Otherwise, it's stealing another  
persons ideas.  You are welcome to get a PhD in Math and come up with a  
different algorithm that is simple, easy to implement, and relatively secure.   
Then you can give it away, or patent it and make money on it.
