If you implement RSA from the textbook, as a simple formula, you'll leave yourself vulnerable to padding based attacks that can recover the private key. It turns out that though the formulas are straightforward and the math can be explained after a decent undergraduate education, the implementation is still very subtle.

padding attacks are only really related to encrypting data not sharing the product of two very large primes. You clearly havent got the faintest idea what you are talking about.

Rather than putting the rest of us at risk by putting zero value on the security of anything you make and guessing someone [a spook] will do it for you, why dont you recommend everyone takes some time out to at least learn the basics.

Yes, there are several "mines" you need to be wary of.

But they all pale into insignificance compared to linking openssl and thinking you are done.
