testing - How do I test the quality of an encryption algorithm? -


I want to test encryption algorithms for strength. It does not have to be strong, it is only to resist accidental cracking and to say, a determined hacker who has been done to waste 10 hours. (I have written. Yes, I know that this is usually a bad idea, but I think that I have good reason.)

How should I check? So far I have tried to do this:

  • Generate random A.
  • Flip a random bit of A to make B.
  • (A) XOR encrypt in 1A encryption (B) leaves a poseon distribution (except that the XOR output is never done).

Any other suggested test?

About encryption

This is a standard fiesta cipher Designed to run in 3ns and completely Be Organizing, No Registered. (It is an order of greater intensity than DES / AES / etc.) I do the rounds as much as I can in 3ns, which is about 6 only.

First I sort the order of input bits.

Then the output of the F function for each bit of I's x-ray on the left half of the input is 3-bit and output is 1-bit. 3 input bits are selected from the right half of the input. The output of F is a permutation of {00001111}, so F is balanced 3 input bits are chosen from the bits on the right half so that the use of each bit on the right half is equal to the time (or as close to as possible). Each "F" is generated randomly and freely once.

Next I swap left and right part of the result and do it again. Then, new "F" for each bit with new input

It's all a round, I do it six times, take a random, independently created F function 6 rounds 3ns, I tried to change the number of fodder and the number of f is.

The strength of your encryption algorithm

Keep in mind that this is likely to be a one-stop use, at least spend in those two years for: -)

html - CSS autoheight, but fit content to height of div -

I have a div in which there are three children- div in the left and middle div: float: left while true: float: true because it is my layout Actually will spoil, I've used ClearFix Hack: .cf {zoom: 1; }. Cf: First,. Cf: {content: ""; Display: Table; }. Cf: After {clear: both; } It still works, but I want to be the right div an indicator. So it should fill 100% of the parent unit of height. How can I complete this? PS is the full code: & Lt; / Div & gt; & Lt; Div class = "mobile_content" & gt; & Lt; H5 & gt; {{Data.titel}} & lt; / H5> & Lt; Table & gt; & Lt; TR & gt; & Lt; Th & gt; Komponist: & lt; / Th & gt; & Lt; TD & gt; {{Data.komponist}} & lt; / TD & gt; & Lt; / TR & gt; & Lt; TR & gt; & Lt; Th & gt; Instrument: & lt; / Th & gt; & Lt; TD & gt; {{Data.instrumente}} & lt; / TD & gt; & Lt; / TR & gt;...

qt - How to prevent QAudioInput from automatically boosting the master volume to 100%? -

I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%. How can I prevent QAudioInput from changing the master volume? My current development platform is Linux with PalsAdio (with flat audio disabled). How can I use QAudioInput : QAudioDeviceInfo device_info = QAudioDeviceInfo :: defaultInputDevice (); QAudio format format; Format.setSampleRate (44100); Format.setChannelCount (1); Format.setSampleSize (16); Format.setCodec ("Audio / PCM"); Format.setSampleType (QAudioFormat :: SignedInt); Format.setByteOrder (QAudioFormat :: LittleEndian); Std :: cout & lt; & Lt; Device_info.deviceName (). ToUtf8 (). ConstData () & lt; & Lt; Std :: endl; QAudioInput * default_device = new QAudioInput (device_info, format); QIODevice * default_io_device = default_device-> Start (); a QAudioInput.setVolume () method is not you I ...
