Hello people again, I wrote my last post about crypto about 10 months ago, now I will introduce something not fresh for the science, but fresh for the people who wants to learn. In my http://null-byte.wonderhowto.com/forum/cryptography-0161538/ post of crypto concepts, there is just basics, today we will see something that targets wide concepts like Symmetric crypto, Public Key Cryptography, Hashing, Keys etc...
If you're seeing "damaged" apps on your Mac, you're not alone. A huge digital rights management blunder in Apple's Mac App Store on Wednesday, November 11th has rendered some apps unusable. When opening certain apps, the following message could be displayed:
Those of you who have been a part of the Null Byte community for even a short while know that I sincerely and firmly believe that hacking is the most important skill set of the future.
If you own an iPad 2, a 3rd or 4th generation model, or original iPad mini, then you won't be able to utilize the new multitasking elements introduced in iOS 9. Although many iPads can use the Slide Over and Picture-in-Picture features, only the iPad Air 2, iPad mini 4, and iPad Pro have the ability to perform Split View.
Flowers may be beautiful, but they're not usually appetizing. Sure, nasturtiums are hip in fancy restaurants, but they're primarily used as a garnish. Granted, fried squash blossoms are incredible, but the point remains: flowers are usually reserved for looking at, not masticating.
Fiddlehead ferns look like something from Alice in Wonderland, or something that you might see when you close your eyes while listening to Pink Floyd and enjoying some herbal refreshment. What they don't look like is a tasty vegetable that's perfect for any spring or summer dish. Yet that is exactly what these bizarre spirals are. What Are They?
With the purchase of my new Apple Watch, the days of striving to be a James Bond-like spy have never been closer to fruition. Granted, talking to your wrist in public can look pretty pretentious, and I may very rarely do it, but let's get real—you look like 007!
Apple Watch doesn't include a multitasking feature like its iPhone companion, so there's no way to show active apps or swipe up to force-close one. Watch is an extension of the iPhone, not a replacement, so including a fully-functional multitasking feature seems impractical.
Video: . I made this Tesla Coil using the myRIO and LabVIEW. It uses electricity to play the music, which can be Star Wars, Harry Potter or even Hunger Games! The music is played by the spark heating the surrounding air (causing it to expand) then the spark turning off (causing the air to cool and contract). This expanding and contracting cause's longitudinal waves - or sound waves.
Before heading out on a hike, or any excursion for that matter, it would be wise to take a map with you just in case you get lost while on your quest.
Our first stop at CES this year was at iLuv, a company well known for their long line of smartphone accessories (portable chargers, speakers, headphones, etc). While their products are geared towards everyday use, their Selfy phone case, which is a bit more situational, caught our attention.
Last year, The New York Times wrote that certain restaurants in Manhattan and Brooklyn banned patrons from taking photos of their meals. That means no flash photography, no standing on chairs for a better angle, not even a quick pic for your Instagram followers before the first bite. Little do these restaurants know, this ban can actually make their customers' food taste worse, so to speak.
Think eating food is as easy as putting it in your mouth? It's considerably more complicated than that. Your brain plays a big role in determining what and how you eat. Understanding how your brain interprets food choices is key to managing your eating habits.
Facebook wants to take your browsing history and sell it to advertisers. Video: .
Many of my aspiring hackers have written to me asking the same thing. "What skills do I need to be a good hacker?"
One of the down-sides of international long-haul travel is layovers between flights in unfamiliar places. We have a flight to Europe this year via Guangzhou, China, and I've been putting together my notes on how to make the best use of 7 hours between flights, which I'd like to share.
The original Kit Kat was a mutton pie served at a political club in London during the 18th century, which is quite different than the chocolatey version we're familiar with today. Kit Kat bars have been around since 1911, are produced in 13 countries, and have been sold in over 200 flavors in Japan.
Do you have a passion that you would like to share with the world, but not sure how to do it. If so, that was my story too. I knew the niche I wanted to share, but I had no computer, video editing, website, or any other digital experience.
The Xperia Z1, Sony's flagship device, has been extremely popular overseas, so much so that it has made its way into the U.S. market as the Xperia Z1S, a modified version of the original. Known more commonly as the "waterproof smartphone," the Xperia Z1 packs one of the most powerful cameras on the market, with an impressive 20.7 megapixels. Since the device is only available for T-Mobile here in the States, unless you currently have that carrier, the chances of you getting your hands on Sony...
Welcome back, my hackers novitiates! As you read my various hacking tutorials, you're probably asking yourself, "What are the chances that this hack will be detected and that I'll land behind bars, disappointing my dear mother who already thinks I'm a loser?"
There are thousands of fonts you can download online. Some are free, some you have to pay for, but they all have something in common—if you can get them, so can everyone else. If you want a truly unique font that no one else is using, you have to make your own, and what's more unique than your own handwriting?
As a preventative measure against exploitation, certain Android applications won't work if your device is rooted. Opening one of these apps that detects root will typically end up with a warning and an inability to access its features, like in the picture below. AS IF!
Whether you have AT&T, Verizon, Sprint, T-Mobile, or any other mobile carrier, chances are your smartphone is sold locked to only work on that specific carrier's network. Sure, you could unlock your carrier-subsidized device, but that would mean breaching the Library of Congress' latest Interpretation of the Digital Millennium Copyright Act—making the whole process illegal. As softModders, boundaries and regulations are things that we don't take lightly, although many times we have to begrudg...
No, we aren't talking Pinterest here, we're talking your Xbox One dashboard. You can pin your favorite apps and digital downloads to the Xbox One home screen for quick access, just like you can on the Xbox 360. It's similar to the Windows 8 tiles, where you can bookmark certain apps in place. All you need to do is go to your Home Screen by either saying, "Xbox, go home," or hitting the Xbox button on your controller. Then, locate and select the game, music, video, or app that you want to pin ...
Why can't Thanksgiving be a celebration of fireworks, too? This year, it can be with an innocent looking pumpkin pie that erupts an insane fountain of flames and fire! In fact, the pie filling is actually a flammable mixture of sugar and potassium nitrate, which was made using the same process as my DIY smoke flares with fuses.
Whether you're trying to get an unconventional angle or just want to include yourself in the picture, there are plenty of times when a remote trigger can come in really handy. Of course, if you want to buy one, you have tons of options. But if you already have an Xbox 360 headset, all you have to do is plug it in. YouTube user Gurnarok accidentally found that by plugging his Xbox headset into his camera's remote port, the on/off toggle triggered the shutter release and flash.
According to WitsView, 8-inch displays will rule the tablet scene this year at 11.9% market share, compared to yesteryear's 2.6% market share. By year's end, it'll be almost 18%.
Having to read a bunch of articles and tweets everyday can be tiresome, but if you can have a sweet-ass personal assistant read them for you, you're pretty golden.
Cassette tapes, much like the boombox, Walkman, and record player, aren't used much anymore. With the ability to put music on our smartphones, most of us don't carry tapes or CDs around because it now seems inconvenient.
In photography, bokeh refers to the blurry or out-of-focus parts of a shot. Bokeh can be good or bad—it all depends on how you use it. There are tons of ways to create a bokeh effect, whether you go the traditional route with lens filters, digital with Photoshop, or even from your iPhone. With filters, you can use the blurred spaces to produce different shapes and colors. If you have a DSLR and want to experiment with bokeh, this tutorial by Chris Perez over on Apartment Therapy will show you...
With all of the advancements in the smartphone world, we can virtually use them for anything. You can use your smartphone as a mobile hotspot, an Xbox controller, a car locator, and a security camera. Heck, you can even turn it into a Swiss Army knife. And now you can even use it as a wireless mouse for your computer!
Remember how the bad guys in Scooby Doo would always use cut-out portraits to spy on people through walls? Well, unless your landlord is super cool, you probably shouldn't start cutting holes in your wall just yet, but you can make a higher tech version, thanks to NASA employee Mark Rober. Mark used a cheap picture frame and a portrait with the eyes cut out to make the "Scoob Cam," which also doubles as a surveillance device. He used an iPhone and an iPad to start a FaceTime chat, then taped ...
While graffiti may never be fully accepted by the masses, it has already become a very large medium for creative artists across the globe, who make mundane and austere cityscapes a little more interesting for the rest of us. Walking past this Banksy stencil on my way to class (at UCLA) made my day. Art like this can cause people to stop and appreciate the otherwise boring and blank walls that surround the city. It can stir up artistic feelings, pensive thoughts, and other emotions stored insi...
Keys are on the way out. They're clunky, take up precious space, and slow you down when you have tons of identical-looking gold ones on your keyring. Everything we can open with keys can now also be opened with wireless technology in just a click—so why use keys anymore? Sure, you can pay hundreds of dollars for an automated lock system on your house—but why do that when you can build it yourself!
Wet-plate collodion photography is a process that lets you develop a photo onto a piece of glass. It has some neat applications, but it's not a simple process, and most people use a special camera to do it because the silver nitrate used to process usually ends up leaking, which would ruin a regular camera.
Still have an old tape deck installed in your car? This nifty hack lets you upgrade to the digital age without sacrificing your love for cassettes. There's nothing wrong with some low-fidelity tunes in your car every now and then, but if you want to listen to the tunes on your iPod or smartphone too, it's a lot easier (and cheaper) than buying a new in-dash player that supports line-in connections. Just add some wireless capabilities to you tape deck! All you need is a cheap cassette adapter,...
Before my time, people used to listen to music recorded on these things... I didn't really know what this thing was until my parents clarified and told me that they were called cassette tapes. These "cassette tapes" were utilized to store sound recordings on either side of the tape, which could usually hold between 30 to 45 minutes. I laughed at that information as I took out my iPhone 5 (roughly the same size), which can store roughly 40,000 minutes worth of music.
Planning on getting the iPhone 5, but want to keep your SIM card? The new nano-SIMs that manufacturers are adopting will be even smaller than the micro-SIMs that most of us currently use. It's fairly easy to cut a regular SIM down to a micro-SIM, but because the nano-SIM will be thinner as well as smaller than the micro, cutting it down to size will require a little more work.

As useful as they can be, 360-degree photos are a total pain to create. The process usually involves taking a bunch of pictures with expensive equipment or software, and not just anyone can do it. But a new iPhone app called CupChair changes everything—it lets you take 360-degree photos with nothing but your iPhone and a cup.
Technology is awesome. You can use your iPad to record music or even turn your tunes into a solar system, but sometimes being plugged in all of the time can leave you nostalgic for simpler times. This new concept by Joelle Aeschlimann brings together the best of both worlds by turning your iPad into an old-fashioned, hand-cranked music box. The artist created three different music boxes, each one with its own unique song and visualization. The music boxes were made using wooden cylinders with...
