Looking for a license key algorithm. In all honesty, what youre trying to do is pointless. However much time it takes you to write a validationencryptionkey system, estimate roughly half that for someone to break it. Even if you encrypt the final executable. However, as a delaying measure or a way to decrease the chance of people getting premium support for stolen copies, it will help. Sending files over the Internet is common, and sending those files securely is vital to many businesses. There are a number of ways you can transfer files. There are a lot of questions relating to license keys asked on Stack Overflow. But they dont answer this question. Can anyone provide a simple license key algorithm. How do we get and append x509data and x509certificate tag to the xml produced by the following code String providerName System. Propertyjsr105Provider, org. Gp Cricket Games For Mobile Java there. Crossdomain loading may allow a remote SWF to have unintended access to the loaders domain and data. If the loading SWF imports the remote SWF file into its. Version In general this should indicate version 3 X. Since the numbering starts from zero this will have a value of 2. If omitted version 1 value 0 is assumed. Installation of the CAPICOM library. This library is used to digitally sign data, verify digital signatures, envelop data for privacy, hash data, encryptdecrypt. I have three certificates in a chain root. When I examine them using openssl x509 in filename text noout they look fine, root. Openssl Digitally Sign File' title='Openssl Digitally Sign File' />Also for simple tracking of buyers. Or for fun. p. Anyway, there are a few ways you can handle it. A lot of software uses name and possibly company strings and a hash function to generate a key. This has the advantage of being constant as long as the name is the same, the hash is, and so the key is. It is also a very simple system, especially if you use a well known hash such as MD5. Some fancier apps use an internal function to generate a validation code of some sort, and when you combine that and the given name, you can create and send back a hash. Openssl Digitally Sign File' title='Openssl Digitally Sign File' />Code get. Codename. Hashname valid. Code. A few use a system based code Windows is a good example, where it samples bits of hardware and builds an identifier from that. If you can get ahold of the processor name or speed, or anything else, you can run something like that. The only problem is system changes can render a code invalid, so you can either warn your users and give away part of the process or let them find out accidentally not good. ID processorname ramSpeed. ID name. You can use any combination of hash functions, data gets, string inputs, boolean operations, etc. One thing to consider is you dont need to be able to reverse the process. As long as you can replicate it with the same results any good hash function can, you can check the hashed results against each other and make sure its valid. The more you put in, the more complicated itll be, but the harder itll be to crack. Hopefully that helps with your question. Creating more secure SWF web applications. Prerequisite knowledge. You should have an understanding of Action. Script 2. 0, Action. Script 3. 0, and Flash Player. Knowledge of Flash CS4 Professional or Flex is encouraged but not required. Additional Requirements. Flash CS4 Professional optionalFlex Builder 3 optionalNote This article was originally authored for Adobe Flash Player 9,0,1. Flash Player 1. 0. Changes to this article were made to reflect updates to cross domain HTTP and socket policies, user initiated action requirements, and other protections added in Flash Player 1. The article was also updated to reflect recent projects, clarifications on Flash Player port usage, and additional best practices. Adobe frequently updates the Flash Player software security model to improve the security of the Flash Player environment. However, that only addresses half of the overall solution to help securely deploy applications that run in Flash Player. As the web developer, you must also correctly leverage the tools provided by the Adobe Action. Script language and the Flash Player platform to help ensure that your SWF files are more secure. Poor programming conventions can expose SWF files and the sites that host them to web attacks. Base64 Hash Cracker Load. Adobe provides many resources for developerssuch as the Flash Player security section of the Programming Action. Script 3. 0 for Flash documentationto assist with developing more secure code. This article outlines many of the security considerations associated with common tasks and provides samples of techniques that can be used to help secure code against those threats. Links to the full documentation are provided throughout the article for further reference. These techniques are designed primarily for the Adobe Flash development environment but they can also be applied by Adobe Flex developers. This highly technical article presumes that you have some knowledge of the Action. Script language and Flash development. Due to its length, the article is broken up into different sections based on what you are trying to accomplish as a developer or administrator If you are an administrator who deploys Flash applications, you will be interested in the sections on HTML controls, domain segmentation, cross domain policy files, and socket policy files. If you are a developer who creates simple, self contained SWFs such as advertisements, you will most likely be interested in the sections on data validation on URLs, Java. Script communication, and local shared objects. Most of this article is targeted for those who create complex websites using the Adobe Flash Platform. Throughout the article, there are links to additional resources for greater detail on all the issues discussed. Potential threats to SWF files. This section provides a brief overview of the different high level threats that you should consider when developing SWF applications. Although there are more granular threats that could be defined within a specific context for any SWF file, this overview covers the high level threats common to most SWF deployments. Throughout the rest of the document, Related Threats entries will map these threats to specific Flash Player APIs and concepts. Each section will then describe the mitigation strategies that apply to the identified threats. Cross domain privilege escalation. Cross domain loading may allow a remote SWF to have unintended access to the loaders domain and data. If the loading SWF imports the remote SWF file into its security domain, then the loaded SWF could gain access to the parent SWFs data and relay that data back to an attacker. In addition, depending on settings within the web page, the loaded SWF could inject script into the loaded SWF files web page. These attacks could occur whenever the end user can gain control over movies that are loaded by a parent SWF file. Cross domain privilege escalation is a high level threat that can expose a SWF to more specific threats such as spoofing, script injection into the browser, malicious data injection, DNS rebinding and insufficient authorization restrictions. This threat exists whenever content from multiple remote sources is loaded and processed under a single security domain. A remotely loaded SWF may try to render its controls over the top of the loading SWF in an attempt to perform a spoofing attack. By overlaying the parent SWF, the malicious SWF can hijack control from the loading SWF file. For instance, if developers do not set masks on Loaders to limit the remote SWF file to a particular area of the Stage then an attacker could perform a spoofing attack. Injecting malicious data into applications is how most vulnerabilities are found by attackers. A Flash application may receive malicious data injection from several types of interfaces. For example, it is common for Flash. Vars to be set via the Object tag within the HTML. However, developers sometimes forget that these variables can be set via the URL where it is trivial for an attacker to alter the values. For example, if the Flash. Var value is a URL that points to remote content such as another SWF, then the attacker could alter the URL to point to a malicious SWF instead. In Action. Script 2. URL as a Flash. Var. In Action. Script 3. Flash. Var variable and manually assign that value to an internal variable. Other examples where malicious data inject can include any time a SWF loads remote datasuch as when a SWF file obtains data from a Local. Connection, the SWF file remotely loads variables from a server, or the SWF file imports data from another SWF file. A SWF file will be exposed to this threat if you do not perform data validation on remotely obtained data. Script injection into the browser. In some instances, website owners may host third party SWF files on their site. However, the website owners may not want to grant the third party SWF files read and write access to their HTML or Java. Script code. Incorrectly setting permissions could allow an attacker to rewrite the entire page or redirect the users from the trusted site to a phishing site. This threat exists for web administrators that host third party SWFs as well as for SWF files that accept URLs via Flash. Vars. The most common vulnerability to consider is an attacker injecting data in order to conduct a cross site scripting XSS attack. Assume that the target SWF takes a URL value from a Flash. Var and sends that information to a navigate. To. URL or a get. URL command. An attacker who notices this behavior may try to replace the original URL value of the Flash. Var with a javascript URL. Java. Script URLs sent to the browser through get. URL or navigate. To. URL methods will execute within the context of the domain hosting the SWF. Teamviewer 7 License Key Generator. The javascript URL can contain any set of Java. Script commands including commands to steal the cookies from the domain and forward them to a third party site. A cross site scripting attack could also occur if a malicious remote SWF is imported into the trusted SWF and then the remote SWF calls a javascript URL. These attacks can be considered to be a special subset of the malicious data injection attacks. They are separated out from malicious data injection because, as we will discuss later, Flash Player has controls that can help prevent cross site scripting attacks but would not prevent the more general data injection attacks. Insufficient authorization restrictions.
