Software cracking Software cracking is the modification of software to remove or disable features which are considered undesirable by the person cracking the software, usually related to protection methods: (copy protection, protection against the manipulation of software), trial/demo version, serial number, hardware key, date checks, CD check or software annoyances like nag screens and adware. The distribution and use of cracked copies is illegal in most countries.[citation needed] There have been lawsuits over cracking software.[1] A computer program that performing software cracking is called crack, or is euphemistically referred to as a patch.

Email Security using Public Key Cryptography Introduction Anyone using Email that is concerned about the security of the data being transferred should use Public Key Encryption. There are several open source software tools like GnuPG and WinPt to accomplish these tasks. The primary benefit of public key cryptography is that it allows people who have no preexisting security arrangement to exchange messages securely. The need for sender and receiver to share secret keys via some secure channel is eliminated; all communications involve only public keys, and no private key is ever transmitted or shared.

'Uncrackable' codes set for step up 4 September 2013Last updated at 13:09 ET By Melissa Hogenboom Science reporter, BBC News Quantum cryptography is a way to share secret digital keys A system that allows electronic messages to be sent with complete secrecy could be on the verge of expanding beyond niche applications. A team of British scientists has discovered a way to build communications networks with quantum cryptography at a larger scale than ever before. Quantum cryptography has the potential to transform the way sensitive data is protected. Details appear in Nature journal. I Love Free Software5 Best Free Network Packet Sniffer Here are 5 Best free network packet sniffers that does a fantastic job of packet sniffing. These free packet sniffer can analyze network packets of all outgoing traffic, and analyze information from them. Before we go further, here is a definition of a Packet Sniffer from Wikipedia: A packet analyzer (also known as a network analyzer, protocol analyzer or sniffer, or for particular types of networks, an Ethernet sniffer or wireless sniffer) is a computer program or a piece of computer hardware that can intercept and log traffic passing over a digital network or part of a network. As data streams flow across the network, the sniffer captures each packet and, if needed, decodes and analyzes its content according to the appropriate RFC or other specifications. As mentioned in definition above, a packet sniffer is also able to sometimes decode and analyze network traffic to extract useful information.

Top 15 Security/Hacking Tools & Utilities 1. Nmap I think everyone has heard of this one, recently evolved into the 4.x series. Nmap (“Network Mapper”) is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics.

An Overview of Cryptography 1. INTRODUCTION Does increased security provide comfort to paranoid people? Or does security provide some very basic protections that we are naive to believe that we don't need? During this time when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for commerce, security becomes a tremendously important issue to deal with. PRISM - Where do we go from here? In light of the shocking revelations regarding the United States surveillance machine (the National Security Agency) and their PRISM initiative - one has to ask how do we move forward? As you can see from my previous blog post, I have personally written to President Barroso of the European Commission asking that the Commission immediately revoke the Safe Harbour status of the United States, ban all US companies from EU markets until such time as the US Government acknowledge and uphold the fundamental and constitutional rights of European citizens and begin a formal investigation into the allegations that the UK Government's signals analysis agency GCHQ used PRISM to circumvent the legal processes in place governing the acquisition and interception of citizens' communications. People have already started to ask me to recommend some alternatives to the popular services we use online, to be honest there aren't very many. For the above reasons, I once again turn my old friends at Ixquick.

Network Defense and Countermeasures: Assessing System Security Perhaps the most critical step in assessing any network is to probe the network for vulnerabilities. This means using various utilities to scan your network for vulnerabilities. Some network administrators skip this step. They audit policies, check the firewall logs, check patches, and so on. However, the probing tools discussed in this section are the same ones that most hackers use.

Hack Edit Article Two Parts:Before You HackHackingCommunity Q&A Primarily, hacking was used in the "good old days" for learning information about systems and IT in general. NSA surveillance: how to stay secure Now that we have enough details about how the NSA eavesdrops on the internet, including today's disclosures of the NSA's deliberate weakening of cryptographic systems, we can finally start to figure out how to protect ourselves. For the past two weeks, I have been working with the Guardian on NSA stories, and have read hundreds of top-secret NSA documents provided by whistleblower Edward Snowden. I wasn't part of today's story – it was in process well before I showed up – but everything I read confirms what the Guardian is reporting. At this point, I feel I can provide some advice for keeping secure against such an adversary. The primary way the NSA eavesdrops on internet communications is in the network. That's where their capabilities best scale.

Is It the Dawn of the Encryption App? We might live in an age of persistent and pervasive surveillance. The recent revelations about the secret National Security Agency programs aimed at collecting vast amounts of data on Americans and foreigners seemingly confirm what tinfoil-wearing netizens have feared for years: They're watching us; technology has turned against its users. Amidst prying eyes, a small but growing group of hackers and programmers is working on applications that use cryptography — the science of creating techniques to hide data and render it readable only to intended recipients — to fight surveillance and give regular citizens access to what was once only reserved to computer experts.

Change NTFS file and folder permissions Hi Fellows!Have you ever experienced no permission to access a directory, which is very impotent to you when you are the only administrator account? Message like this, Then this message, When you go to security tab, still not allows to changing the permission of that particular directory. Here is solution, you can change NTFS file and folder permissions using magic command called "icacls".Step1:Open command prompt and type following command to see the permissions list (discretionary access control lists - DACLs)icacls [folder or filepath]oricacls [folderpath] *

DS Fanboy's (semi) ultimate homebrew guide by Alisha Karabinus on May 20th 2008 11:00AM Where there's a system, there's a community of hobbyist programmers willing to tear it down, build it back up, and make it better, and they've been doing it to the DS from nearly the moment the handheld hit shelves. As the necessary hardware has grown cheaper, easier to use, and more widely available (when not sold out), the DS homebrew community in turn has grown stronger, producing some applications that are so good, they rival (or better!) similar commercial products. But with all of the homebrew solutions available, how does someone new to the scene know where to start?
