tls1.2

问题 My app is using images from HTTPS source, Solar Dynamics Observatory, and these images are loading just fine on Android versions with API 21 (5.0) (I think that API 20 would work as well) or higher, but I can't load these images on Android versions from API 16 (min. API that I set for my app) to API 19. Here's the code that's loading the images, it's pretty basic - Picasso.with(this) .load("https://sdo.gsfc.nasa.gov/assets/img/latest/latest_2048_HMIIC.jpg") .placeholder(R.drawable

问题 After 2018 June 30th, Paypal won't accept non-TLS 1.2 + HTTP 1.1 requests anymore. They created the URL https://tlstest.paypal.com/ to test if connections are OK. If we open this URL in a browser, we get a successful: PayPal_Connection_OK Quesiton: why does it fail when connecting from PHP with the following code? (I get no response at all, the browser is still in waiting "state" like this, so it doesn't even arrive at echo $errno; echo $errstr; ) <?php $req = ''; // usually I use $req = 'cmd

问题 We have a web app hosted in an Azure Server (using api in an Azure Server). For security purposes we'd like to know if the server is under tls 1.2 (I suppose for a non-cloud server we'll just have to see in regedit to know it). I've seen topics on how to disabled ssl 3 from an azure server see at : https://azure.microsoft.com/fr-fr/blog/how-to-disable-ssl-3-0-in-azure-websites-roles-and-virtual-machines/ I suppose to enable tls 1.2 we'll have to do this kind of things ... So my questions are

问题 The new certificate is "Symantec Class 3 EV SSL CA - G3". The client has CentOS. There is no control over the server, it is third party. When the WDSL https address is loaded in Firefox and Chrome, both browsers show "Secure connection", no problem. The WSDL address is https://palena.sii.cl/DTEWS/CrSeed.jws?WSDL Test code: $success = false; $attempts = 0; while (($success === false) && ($attempts < 10)) { $attempts ++; echo 'Attempt ' . $attempts . '<br>'; try { $wsdl = 'https://palena.sii.cl

问题 I'm developing an Android application that communicates with my device(ARM based device with bluetooth module) via bluetooth using TLS(TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256). What I considered: javax.net.ssl from Android. Problem is that ephemeral(ECDH E ) encryption keys are starting from API 20 but I need API 11. I didn't find a way to add suite. It seems that this library is strongly related to android version. API versions and overview Bouncycastle(spongycastle) I didn't find a way to use

问题 My initial problem was that when I was using IncludeCipherSuites option in jetty configuration file, only TLS 1.2 was being supported. Please see below post for details: Jetty IncludeCipherSuites enables only TLS 1.2 Based on the comments it appeared that if I don't provide ExcludeCipherSuites in my jetty configuration file, jetty default exclude cipher list is being used and many ciphers which I explicitly enabled by IncludeCipherSuites option were being excluded (if they are in jetty

问题 I need to fetch the full html of of a page produced by an Amazon Web Service. My question has to do with why I am unable to obtain this html from the AWS servers. The AWS service provides an initial URL (URL #1) which is normally processed by a browser. URL #1 returns a Status of 302 and the URL of a redirected page (URL #2). This works fine when a browser works with these URLs. However, when our Java code below runs we get a Status of 404 for URL #2 and a runtime error of: java.io
