- $\begingroup$ This makes a good point, using a second encryption scheme which is a strong contender with AES would make sense to increase security significantly as opposed to re-inventing the wheel (or at least making my own "wheel"). Would +1 but can't due to rep. However, the linked post isn't quite accurate to the situation. They all deal with educated guessing or suspecting common phrases in the unencrypted text, where as I am encrypting something then performing a two+ pad on it. The underlying bits wouldn't really be "guessable" as far as I know? Still a good read, though. $\endgroup$Thomas F.– Thomas F.2014-07-17 19:29:00 +00:00Commented Jul 17, 2014 at 19:29
- $\begingroup$ Also should be noted I'm not interested in implementing this, and will more than likely just add another layer of security if I went that route (I trust AES so I don't really think it's a huge issue), but the way I see it still is even if they were able to get 100 of the files that were represented in the encrypted files as well (Through finding them on the drive, not decryption), it still wouldn't really help them break the XOR pad since there's still a layer of AES separating it. Or am I looking at that wrong? Thanks for the answer, as well! $\endgroup$Thomas F.– Thomas F.2014-07-17 19:32:17 +00:00Commented Jul 17, 2014 at 19:32
- $\begingroup$ @ThomasF., whether those attacks in particular would apply would depend on how AES would be broken. For example, if the attacker knew how to discern patterns in AES output, that might be analogous to knowing patterns in English. $\endgroup$otus– otus2014-07-17 19:32:51 +00:00Commented Jul 17, 2014 at 19:32
- $\begingroup$ That's true, in which case my previous (second) comment would be rendered moot as they could then use those 100 files to essentially guess between the layer of AES. $\endgroup$Thomas F.– Thomas F.2014-07-17 19:33:59 +00:00Commented Jul 17, 2014 at 19:33

How to Edit
- Correct minor typos or mistakes
- Clarify meaning without changing it
- Add related resources or links
- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
- create code fences with backticks ` or tildes ~ ```
like so
``` - add language identifier to highlight code ```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- quote by placing > at start of line
- to make links (use https whenever possible) <https://example.com>[example](https://example.com)<a href="https://example.com">example</a>
- MathJax equations
$\sin^2 \theta$
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. public-key), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
