tls1.2

In my local PC Braintree showing error "The request was aborted: Could not create SSL/TLS secure channel" when executing : var clientToken = gateway.ClientToken.generate(); I am using "Braintree-2.33.0.dll" and my target .net version is 4.5.1. I have enabled TLS 1.2. It was working nicely three days ago. But suddenly started showing error. Many people faced same error and most of then have changed the SecurityProtocol . I dont find any way to change that from braintree. Is there any way to change ServicePointManager.SecurityProtocol for braintree ? or anything else I am missing or need to do ?

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=_notify-validate'; for IPN $header .= "POST / HTTP/1.1\r\n"; $header .= "Host: tlstest.paypal.com\r\n

Sorry if my question seems redundant. I found tons of Q&As on stackoverflow and a bunch of other resources about enabling TLSv1.1+ for Tomcat, for Java Clients, for OSes..., but still I can't enable it on my local env on Win10/Tomcat7/Java7. Probably, I'm just getting something wrong. So, to be clear, I have a java web app deployed on tomcat. This web app makes requests to remote services via https. Previously these remote services supported TLSv1.0, and my app worked fine. Now these remote services support only TLSv1.1+, and I'm getting an error/actually a simple html page response saying: To

We have a Java app on Google App Engine. We use Google's custom domains and SSL support. A recent security audit has found two issues that we need to resolve relating to the SSL configuration: 1) The server-side SSL/TLS endpoint is configured to allow weak SSL/TLS cipher suites. Specifically: block ciphers having block size of 112 bits - DES, 3DES and Cipher suites that use block ciphers (e.g. AES, 3DES) in CBC mode. 2) The server-side SSL/TLS endpoint is configured to allow connections using TLS protocol version 1.0 ("TLSv1.0"), which contains known weaknesses Looking at the App Engine docs,

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 : - How to know if the azure server is under tls 1.2 - if not, how to set the azure server to tls 1.2

I am updating Security protocols to my existing 3.5 .net framework application to work my payment gateways smooth. I have added following code System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolTypeExtensions.Tls12; in my Global.asax in Application_Start but it is giving me compile time error that The name 'SecurityProtocolTypeExtensions' does not exist in the current context I was following this link S upport for TLS System Default Versions included in the .NET Framework 3.5.1 on Windows 7 SP1 and Server 2008 R2 SP1 provided by Microsoft. Update 1: Also tried as told in above

So, this might be a very special case, but I hope someone can help me out here. I need to talk to a peripheral via Bluetooth. A device for which we also control the firmware. Now the issue is: we need to make sure noone can eavesdrop as the information to be sent will be confidential. That means we need an encrypted communication. From what I see is that Bluetooth LE 4.2 supports encryption, BUT we have to be able to support older iPhones than the 6s. That means: no BLE 4.2 and no built in encryption. In other words: we need to build the encryption ourselves. The peripheral developers and me
