security

问题 Starting a new Ember app and was prepared to follow token authentication type structure for authentication in the restricted API routes but was then told we need to not show any of the javascript (or as absolute little as possible) before authentication. This has me a little puzzled given single page javascript apps. I'm using the, very helpful, ember-app-kit which has great tools that compile everything down to a minified and obfuscated single javascript file, which I thought was good enough

问题 From the tutorial But there's a problem! Our rendered comments look like this in the browser: " <p>This is <em>another</em> comment</p> ". We want those tags to actually render as HTML. That's React protecting you from an XSS attack. There's a way to get around it but the framework warns you not to use it: ... <span dangerouslySetInnerHTML={{__html: rawMarkup}} /> This is a special API that intentionally makes it difficult to insert raw HTML, but for Showdown we'll take advantage of this

问题 How can I ref-fill posted form data via PHP in the event of an error. I have a contact form and the user enters a bunch of information and if one field doesn't validate, he loses everything. How can I stop this from happening and make sure it is secure? I've tried this, but believe I read somewhere it is not secure: <input type="text" name="name" value="<?php echo $_POST['name']; ?>" /> 回答1: One issue is that if $_POST['name'] contains a " , then the value can 'escape' out and rewrite the

问题 I am working with some content which I decrypt from a file in Android and which needs to remain for the entire duration of the application in memory. Is this a security risk from crackers? If so, does Android offer some form of in-memory protection of sensitive content similar to Windows' process secure memory access protection mechanism? I am not looking for storage via SharedPreferences in Private mode, I would need some memory zone which is inaccessible for tampering. Would storing data in

问题 I have got a particular requirement where some critical algorithms have to be handled in the client-side script and it got to be secured. Using javascript will just expose the algorithm. I am currently evaluating ways to secure the algorithm on the client script. Appreciate any suggestions and alternative approaches. One option I am thinking about is to download a small applet to the local PC, get the calculations done in it and update the results back. Before deciding on this, I want to know

问题 Here is a simplified version of a program I am using to work with a file using javascript on the client side. HTML: <input id='myinput' type='file' accept='.png, .jpg, .jpeg' /> Javascript: var myinput = document.getElementById('myinput'); myinput.addEventListener('change', function(e) { /* 1. capture the file */ var file = e.target.files[0]; /* 2. make a fileReader object */ var reader = new FileReader(); /* 3. the load event listener */ reader.addEventListener('load', function(e) { var

问题 I am working with a Java Web application and I need to generate a MAC using 3DES algorithm. Code is working without problems on a Weblogic 10.3 but the problem came when I tried to run the application in a different Weblogic, similar version (10.3.1). This is my code: public String getMac(String inkey, String data) throws Exception { byte[] out = new byte[8]; try { // if I commend this line, the result is the same Security.addProvider(new BouncyCastleProvider()); // this loop proves the BC

问题 I have written a class (so I could learn how OAuth works). It is working fine; I can retrieve the access token with the class. But when I try to post an update, it says that I'm not authenticated! What am I doing wrong here? // By Kevin Jacobs class OAuth { private $url = null; private $debug = false; private $method = 'POST'; private $oauthData = array(); private $data = array(); private $token = array('key' => '', 'secret' => ''); private $consumer = array('key' => '', 'secret' => ''); /**

问题 I have custom security token and custom IAuthorizationPolicy , like this: public class TestAuthorizationPolicy : IAuthorizationPolicy { public TestAuthorizationPolicy(string name, string someData, string moreData) { this.Name = name; this.SomeData = someData; this.MoreData = moreData; var claims = new[] { new Claim("http://text.example.com/Claims/Name", this.Name, Rights.Identity), new Claim("http://text.example.com/Claims/SomeData", this.SomeData, Rights.PossessProperty), new Claim("http:/
