Safari: To enable TLS 1.1 and 1.2 in Safari, perform the following steps: 1. There are no options for enabling SSL or TLS protocols. If you are using Safari version 7. Sometimes when there's a bug with a setting, you can work around it by editing operaprefs.ini while Opera is closed instead of using the settings UI. Xforce keygen 3ds max 8 trial. Then again, I remember that Opera stopped enabling TLS 1.1 and 1.2 by default at some point. Maybe Opera eventually implemented forceful disabling of them. Just don't remember. Hack for mu 97d. TLS 1.2 was defined in RFC 5246 in August 2008. It is based on the earlier TLS 1.1 specification. Major differences include: The MD5-SHA-1 combination in the pseudorandom function (PRF) was replaced with SHA-256, with an option to use cipher suite specified PRFs. Mar 25, 2019 How do I tell staff to configure their Apple mail app to not use anything other than TLS 1.2? Connector report in Exchange Online is showing several staff iPhones using insecure TLS when sending mail using the native app. TLS1.0/1.1 Apple-iPhone11C8/1604.57. TLS1.0/1.1 Apple-iPhone8C1/1604.39. TLS1.0/1.1 Apple-iPhone10C4/1604.57. So, typically the browser starts out with offering TLS 1.2. If server behaves properly, we’ll end up on a version between SSLv3 and TLS 1.2. If the connection is closed, the browser retries with TLS 1.1, then TLS 1.0, and finally SSLv3. An attacker can use this to cut the connection over and over to get to the version desired.

Changeset: http://closedjdk.us.oracle.com/jdk8/build/pubs/rev/b76aa6527363With changes to the Security JDK 8 enhancements page:TLS 1.2 Enabled by Default: The SunJSSE provider enables the protocol TLS 1.2 on the client by default. See Protocols. Configure which SunJSSE protocols are enabled with the new system property jdk.tls.client.protocols. See Customizing JSSE.Protocols: http://download.java.net/jdk8/docs/technotes/guides/security/SunProviders.html#SunJSSE_ProtocolsCustomizing JSSE: http://download.java.net/jdk8/docs/technotes/guides/security/jsse/JSSERefGuide.html#InstallationAndCustomization
suggested release note:In client side of SunJSSE, TLS 1.2 is enabled by default, and a new a system property, 'jdk.tls.client.protocols', is defined to configure the default enabled protocol suite.Also need to update the 'Protocols' section in SunJSSE provider of 'Oracle Providers Documentation', and mark TLSv1.1 and TLSv1.2 'Enabled by Default for Client'.
Solution ------------ Define a system property, 'jdk.tls.client.protocols', to configure the default enabled protocol suite [1] in client side of SunJSSE provider. By default, TLS 1.1 and TLS 1.2 (plus other supported and safe protocols) are enabled unless the system property is explicit configured and does not contain 'TLSv1.1' or 'TLSv1.2'. The property string is a list of comma separated standard SSL protocol names. The syntax of the property string can be described as this Java BNF-style: ClientProtocols: ('' SSLProtocolNames '') | SSLProtocolNames SSLProtocolNames: SSLProtocolName { , SSLProtocolName } SSLProtocolName: (see below) The 'SSLProtocolName' is the standard SSL protocol name as described in the 'Java Cryptography Architecture Standard Algorithm Name Documentation'[2]. If the property value does not comply to the above syntax, or the specified value of SSLProtocolName is not a supported SSL protocol name, the instantiation of the SSLContext provider service (via SSLContext.getInstance() methods) may generate a java.security.NoSuchAlgorithmException. Please note that the protocol name is case-sensitive. If the system property is not set or is empty, the default enabled protocol setting in both client and server looks like: Protocol Enabled Enabled for Client for Server -------- ---------- ---------- SSLv3 Yes Yes TLSv1 Yes Yes TLSv1.1 Yes Yes TLSv1.2 Yes Yes SSLv2Hello No Yes If the system property is set to 'TLSv1,TLSv1.1', the default enabled protocol setting in both client and server looks like: Protocol Enabled Enabled for Client for Server -------- ---------- ---------- SSLv3 No Yes TLSv1 Yes Yes TLSv1.1 Yes Yes TLSv1.2 No Yes SSLv2Hello No Yes This update does not impact the API specification of JSSE, JSSE server side and third party's provider. [1] The default protocol suite can be overridden by: https.protocols system property SSLEngine.setEnabledProtocols() SSLSocket.setEnabledProtocols() SSLParameters.setProtocols() and SSLEngine.setSSLParameters() SSLParameters.setProtocols() and SSLSocket.setSSLParameters() or other approaches that customize the enabled protocols.

Xuelei,Is there a webrev for this fix? Also how did you test the implementation for the various methods of setting the system property? I am asking this to assess the extent to which we will need to write test in order to cover any gaps.
A conservative approach may be that in JDK 8, adding a new system property which will be configured to disable TLS 1.2 by default but applications have a handy approach to enable TLS 1.2 by changing this property. In JDK 9 (or earlier if necessary), we can update the system property value to enable TLS 1.2 by default.
