You're making the argument "If I apply good crypto plus crypto which might or might not be good, the worst case scenario is that I end up with crypto which is at least as good as the good crypto."
You're the perfect example of Dunning-Kruger, where your skills at crypto are really bad so lack the knowledge to evaluate your crypto skills. You're exactly the kind of person that advice is aimed at.
- Helmet 10y agoThis 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.

- sbov 10y agoSo rot13 will render my aes useless?
- whatshisface 10y agoPossibly. 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.
- ENGNR 10y agoSo you just need to add an extra layer on another computer surely, or else I could MITM SSL by encrypting/unencrypting it
- rahrahrah 10y agoIt might weaken it, yes.

- rahrahrah 10y agoI thought that was what he was saying. Maybe I misunderstood it.
