![]() ![]() Under this setting, although it seems that we will use the TLS 1.2 or 1.3 (depending on the version of curl library), in case we may still send with TLS 1.0/1.1, we would like to know after the deprecation of TLS 1.0/1.1 on April 13, will the request be fallback to use TLS 1.2 or 1. We are using the curl library to send API to dropbox with the setting of CURL_SSLVERSION_TLSv1. TLS 1.2 support had been added, then dropped from Chrome 29. Google Chrome (and Chromium) supports TLS 1.0, and TLS 1.1 from version 22 (it was added, then dropped from version 21). Also, do you have any recommended way to test on which TLS version our app is really using?Ģ. Partial mitigations to keeping compatibility with old systems setting the priority of RC4 to lower. If receiving this mail is a proof of using deprected TLS protocol version by our app, then the only possible reason may originate from some of our customers who still uses older version of our app, which may be kind of wierd. Does that mean our app did make calls using a deprecated TLS protocol version so that we received this mail? Or, is this just a notification regardless of whether our app communicates with deprecated TLS protocol version?īy testing with our app, it seems that the latest version of our app uses the TLS 1.2 and 1.3 protocol version. have recently made calls to the Dropbox API using a deprecated TLS protocol version."ġ. We have received the mail regarding to this issue, stating that: So how can I run a test to know for sure? Is there a way I can simulate April 13th now? Or monitor traffic? The e-mail I got from Dropbox has got me worried. But I don't trust this as proof that my apps are not using the deprecated protocol. ![]() And the iOS code uses cocopods and references ObjectiveDropboxOfficial and a README.MD that says " The Official Dropbox Objective-C SDK for integrating with Dropbox " which should be OK too. My inspection of the Android code shows the external library of :dropbox-core-sdk:3.1.5, which should be OK. I suppose it is possible that some users of our apps have not updated in all that time, but I would like to know if there is any test I could run to see whether or not the latest versions of my apps are using the deprecated protocol. ![]() Value: 771 SSL/TLS Version Reference TLS 1.I received an e-mail from Dropbox warning that " your app(s) TuneLab Tuning Files have recently made calls to the Dropbox API using a deprecated TLS protocol version." I thought we had updated both our iOS and Android versions over a year ago. The above workaround example would trigger the desired result of version 769 only as it is both less than 770 and greater than 768.Įxample to detect TLS version lower than TLS 1.2: Value: 768 (default input value in custom signature is decimal) Value: 770 (defaut input value in custom signature is decimal) The workaround for this use case is using two And Conditions (a 'greater-than' and a 'less-than') in your custom signature instead to get the same result, as shown below: ![]() Pushing a custom signature with this operator from Panorama 10.X to a 9.X firewall will cause a commit error ”negate unexpected here” when trying to push the signature to the PAN OS 9.X firewall (Figure 2):įigure 1 - showing the 'negate' option not available in 9.X versions and earlier for the 'equal-to' operatorįigure 2 - error received when trying to push a custom signature with the 'equal-to' operator from a Panorama 10.X to a 9.X firewall. The reason is due to the 'negate' checkbox option was added to the 'equal-to' operator starting in PAN OS 10.X (Figure 1). **NOTE: When pushing a custom signature from Panorama PAN OS 10.X version to a PAN OS 9.X firewall: you cannot use the 'equal to' operator for custom signatures in this use case.
