How is NSA breaking so much crypto? (2015)

This comment boils down to: you're wrong and you're stupid.

Also, and quite ironically, you have misinterpreted and are misapplying the D.K. effect. Can you care to explain why the above wouldn't be true? Does an extra layer of bad crypto diminish the effectiveness of the good crypto? It doesn't seem like it would, and OPs statement reads more like a reasonable logical assumption, but I know very little about crypto, which is why I ask.

No, I'm not misapplying DK

Yes, you can find other children comment with specific examples.

> It doesn't seem like it would

More DK: you don't know enough to evaluate how much you know.

So rot13 will render my aes useless?

Possibly. If your rot13 takes longer to rotate a Z than it does and A, then it will leak your Zs through the AES. Similarly, you might accidentally write your own rot13 heartbleed.

So you just need to add an extra layer on another computer surely, or else I could MITM SSL by encrypting/unencrypting it

It might weaken it, yes.
