verification

How can I implement symbolic execution for particular language without using model checking and Finite State Machine (FSM) for example not such as Java Path Finder ? I need a detail about it. for example by what language I can implement this symbolic execution and what other things I need to know? You need: A parser for the language to be symbolically executed that can build ASTs Name resolution (and associated symbol tables), so when your execution engine encounters an identifier it can determine the associated type and value Control flow analysis, so that the symbolic execution engine can

I'm actually creating a web application using PHP and seek help verifying a user. As with certain websites, when you register, an e-mail is sent to you with a confirmation link. How do I implement that in PHP? All I know is that I have to use the PHP mail() function to send the e-mail. Please help. Necessary. Thanks. :) just like with CSRF protection you generate an unique token. $token = md5(uniqid(rand(), TRUE)); You store that value in your session for that email and when the user clicks link in email(you pass token via the query-string ) you compare the two values. To make it more secure

I have a system (Linux & C++) doing intensive signal/image processing operations. I would like to use PGO to improve performance of our application. Are there any risks / potential issues I should be aware of when using PGO ? Are unit tests + E2E tests enough to verify that PGO didn't break anything ? Microsoft has system that is modifying conditional jumps based on the usage statistics plus it condenses frequently used pieces of code into smaller number of pages. This essentially compacts effective memory footprint several times and reduces CPU consumption for 20-50%. This system was

In my application I need to verify whether it's signed or not. If it's signed continue the execution and exit the application if not. The signtool will be used to sign the application. Is there any C# code to do that? Here is a utility method that does it: var signed = IsSigned(@"c:\windows\explorer.exe"); ... public static bool IsSigned(string filePath) { if (filePath == null) throw new ArgumentNullException(nameof(filePath)); var file = new WINTRUST_FILE_INFO(); file.cbStruct = Marshal.SizeOf(typeof(WINTRUST_FILE_INFO)); file.pcwszFilePath = filePath; var data = new WINTRUST_DATA(); data

I have 2 ssh servers behind a nat firewall at a location that changes its wan IP every day. They are always at the same wan IP address on a given time but on different ports. I am connecting to server A this way: ssh -p 22001 karl@x1.example.com and to server B: ssh -p 22002 karl@x2.example.com So I get 2 different host keys for the same IP, and also when the IP changes even a different IP for the same host. I have to go on deleting over and over the other key or the old key (in case of IP change) in the known_hosts file. I am hesitating to turn the key verification off, because this would be
