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...
Unless you're in law enforcement, you won't usually have a flashlight on hand for those rare moments when you need to sift through the dark. However, it is very likely that you will have your phone on you, so you'll have fast access to a bright light with just a few easy taps.
With a slab-style touchscreen device, butt dialing is always going to be a problem. While you're moving about, your phone can unlock itself and give your most recent contact a ring, leading to an awkward one-sided conversation where the other person gets to eavesdrop on everything you're doing or saying at that moment.
Returning your device to stock, whether it is because you need to sell it or just want to receive OTAs again, is not always a simple process. Since HTC has released countless variations of both the M7 and M8 HTC One, it can be a pain in the ass finding the right files and tools to get your phone back to stock settings.
Enabled from the moment you first booted up your device, there's a feature deep in the iPhone's settings that automatically backs up your device in the background. As long as you're connected to Wi-Fi and a power source and your screen is locked, your photos, text messages, apps, and everything in-between gets safely stored to your iCloud account.
There's something primal about the smell of smoking food. Somewhere deep in the recesses of our souls, we remember a time when humans only ate by the fire. Or perhaps that's just something I tell myself. Either way, it's hard to smell smoke and food and not feel like you should be eating. And, as chef Edi Frauneder said in a recent Saveur article, "Grilling is convivial. There's something about this act of coming together over an open flame that just says vacation."
Welcome back, friends! Many times, businesses, friends, and family will lock their zip files with a password to keep their files secure. It is reasonable, and understandable. Well, thanks to hackers, there are many ways to get past this wall of security.
Brought to you by Purdy Paints The art of painting requires excellent tools. And with so many options on the market, it can be hard to find a brand that works for you and your DIY project. That's where Purdy comes in.
Keyboard shortcuts can make using your Mac faster and easier, and leave your mouse feeling archaic. With just a few taps, you can save files, open new tabs, or play a movie—all without using your mouse even once.
Samsung has a long-standing reputation for packing their devices with lots of added functionality, and the Galaxy S6 Edge is no exception. It comes with a nifty feature called "Information stream," which allows you to get quick, at-a-glance information by swiping the edge of your screen back and forth while the display is off.
Contacts on your phone can be messy. Keeping all of those numbers, emails, and addresses organized takes time and, even then, they still may not be be as accessible as you want them to be.
CyanogenMod has always been on the forefront of ROM customization, and its newest release, CyanogenMod 12, is no exception. In the newest nightlies, they have included an updated version of their Theme Engine, which allows you to effortlessly change the way your entire system looks.
These days, phone calls aren't always the best way to communicate with others. Maybe you need to reach people out of the country, or you simply want to have a more visual conversation. Either way, there's a reason why video calling has become so popular.
Mac OS X has finally added a way to use two apps side by side in full screen mode, à la Microsoft's Windows Snap. But since it's only available in 10.11 El Capitan right now, those of us with older systems will have to wait until the El Capitan Public Preview or final build is released later this year.
We recently ran into a serious iPhone 6 issue here in the Gadget Hacks office, where the device was stuck in an infinite bootloop with intermittent red and blue screens (of death?) and an unresponsive touchscreen and buttons. From what we can tell, we weren't alone, though some are experiencing only one or a few of the issues we've had.
While some mobile sites have built-in text-resizing tools, many do not. A lot of those that don't won't even let you pinch-to-zoom. That makes it difficult for people with low vision to read small fonts on their iPhones. In some cases, like with photo captions, even those with perfect eyesight suffer.
It's a modern day nightmare to accidentally reveal too much information on Facebook. I've inadvertently told the world my location more times than I can laugh off, and my friends haven't fared too well either. Just take a look at the requested app permissions next time you're about to click install and you'll quickly realize how much that app can reveal about you.
Team Win Recovery Project (TWRP) is a custom recovery for Android devices and the one used by most softModders, mainly because it has touch-based actions, as compared to the more time-consuming button-based approach that ClockworkMod (CWM) uses.
Something special is happening. Maybe it's your child's first steps or their walk down the aisle. Maybe it's a hit-and-run accident, a flaming meteorite, or your buddy spilling a drink all over himself. These are fleeting moments that need to be captured instantly.
By this point, you've definitely come across an app or two that wasn't designed with the HTC One in mind. Either the resolution is too small, the status bar stays active when it shouldn't, or the font isn't the ideal size. There are ways out there to get that changed, but up until now it wouldn't just change one app—it would change all of them.
LG's new KnockOn feature for the G2 wakes the phone up just by tapping on the screen twice, in lieu of using the power/lock button.
Third-party ROMs like CyanogenMod are the ultimate form of customization for softModders. Hard-working developers offer us alternate Android experiences to replace our often bloatware-riddled stock ROMs.
In spite of the degree of difficulty it is to install, CyanogenMod has steadily climbed the ladder to become one of the most popular third-party firmwares for Android devices.
Regardless of how great your friends and family are, they'll more than likely go through your photographs if they had the chance. Hell, if my friend were to leave his/her phone lying around, I'd go through it—no doubt.
I've been playing around with iOS 7 for a while now, and for the most part, I dig it. It's a nice update for a stale OS, and there are a lot of great new features. But like any good piece of tech, there are a few things to be disliked. Some of these are big issues, and some could be considered nitpicking, but given that I'm fairly used to the older iOS 6 version, they feel big to me. Paper cuts always hurt worse than gashes.
There are many impressive features on a Samsung Galaxy Note 2, but just like any other smartphone on the market, the most used one is the camera. How many times did you take a picture today? Or admire all the selfies in your gallery? Or upload a video to Instagram, Vine, or Snapchat?
In a previous softModder guide, we converted our HTC One smartphone into a legitimate Google Play Edition HTC One, but that conversion cause our bootloader to be locked once again. So, if we ever want to convert it back to a regular Sense-style HTC One, we'll need to unlock the bootloader.
Privacy has been a heated topic in recent months, with everyone now up in arms over unauthorized leaks and exposures. And guess what—tablet and smartphone users are just as vulnerable.
While there are many customization options available for the Samsung Galaxy Note 2, they aren't always easy. The large selection of custom ROMs and difficulty implementing certain hacks and mods can be a nightmare for anyone not well versed in all things Android. But the good news is, it doesn't always have to be complicated.
Dorothy had it right: "There's no place like home." This is especially true when it comes to using your Samsung Galaxy S3, or pretty much any other smartphone, whose most vital button is the Home key.
Don't always believe the marketing hype. "PlayStation Certified" does not mean anything to a softModder. All this indicates is that a smartphone or tablet labeled as "PlayStation Certified" has met the guidelines and hardware requirements issued by Sony to display PlayStation Mobile (PSM) content from the PlayStation Mobile Store correctly. No Nexus 7 here.
Nearly two years ago, Peter Chou, CEO of HTC, confirmed that the company would no longer be locking bootloaders. Whether or not they've actually lived up to this claim is debatable. Any phone bought from a wireless carrier comes locked. Only the new HTC One Developer Edition ships with an unlocked bootloader, and it does not have any carrier add-on software installed.
We go to such great lengths to secure our smartphones. We put passwords on our lock screens, encrypt our data, and install anti-theft programs, but it's never enough—someone, somewhere, will find a way around any protective measure you use, no matter how sophisticated.

Don't be too disappointed if you don't have the spiffy new Kindle Touch, there is an up side. The benefit to owning the older (duller) models is that the firmware remains the same throughought generations, so the hacks retain their usefulness.

Today's Null Byte is going to show you how you can root, and then remove the crappy original screensavers that come installed on th...
