The TLSv1.3 implementation is available in JDK 8u from 8u261 and enabled by default for server roles but disabled by default for client roles. From this release onwards, TLSv1.3 is now also enabled by default for client roles. You can find more details in the Additional Information section of the Oracle JRE and JDK Cryptographic Roadmap.
Note that TLS 1.3 is not directly compatible with previous versions. Enabling it on the client may introduce compatibility issues on either the server or the client side. Here are some more details on potential compatibility issues that you should be aware of:
Channel binding tokens are increasingly required as an enhanced form of security. They work by communicating from a client to a server the client's understanding of the binding between connection security (as represented by a TLS server cert) and higher level authentication credentials (such as a username and password). The server can then detect if the client has been fooled by a MITM and shutdown the session/connection.
Two new system properties have been added. The system property, jdk.tls.client.disableExtensions, is used to disable TLS extensions used in the client. The system property, jdk.tls.server.disableExtensions, is used to disable TLS extensions used in the server. If an extension is disabled, it will be neither produced nor processed in the handshake messages.
In the java.lang.ProcessBuilder implementation on Windows, the system property jdk.lang.Process.allowAmbiguousCommands=false ensures, for each argument, that double-quotes are properly encoded in the command string passed to Windows CreateProcess. An argument with a final trailing double-quote preceded by a backslash is encoded as a literal double-quote; previously, the argument including the double-quote would be joined with the next argument. An empty argument is encoded as a pair of double-quotes ("") resulting in a zero length string passed for the argument to the process; previously, it was silently ignored. An argument containing double-quotes, other than first and last, is encoded to preserve the double-quotes when passed to the process; previously, the embedded double-quotes would be dropped and not passed to the process. If a security manager is set, such as in WebStart applications, double-quotes are encoded as described. When there is no security manager, there is no change to existing behavior; the jdk.lang.Process.allowAmbiguousCommands property can be set to true: jdk.lang.Process.allowAmbiguousCommands=true or false. If left unset, it is the same as setting it to true.
With this JDK release, the "certificate_authorities" extension is supported for TLS 1.3 in both the client and the server sides. This extension is always present for client certificate selection, while it is optional for server certificate selection.
Note that if the client trusts more CAs than the size limit of the extension (less than 2^16 bytes), the extension is not enabled. Also, some server implementations do not allow handshake messages to exceed 2^14 bytes. Consequently, there may be interoperability issues when jdk.tls.client.enableCAExtension is set to true and the client trusts more CAs than the server implementation limit.
As a result of this new feature, the Kerberos client can take advantage of more dynamic environment configurations and does not necessarily need to know (in advance) how to reach the realm of a target principal (user or service).
The 'canonicalize' flag in the krb5.conf file is now supported by the JDK Kerberos implementation. When set to true, RFC 6806 name canonicalization is requested by clients in TGT requests to KDC services (AS protocol). Otherwise, and by default, it is not requested.
The new default behavior is different from JDK 14 and previous releases where name canonicalization was always requested by clients in TGT requests to KDC services (provided that support for RFC 6806 was not explicitly disabled with the sun.security.krb5.disableReferrals system or security properties).
Two new system properties have been added to customize the TLS signature schemes in JDK. jdk.tls.client.SignatureSchemes has been added for the TLS client side, and jdk.tls.server.SignatureSchemes has been added for the server side.
Prior to JDK 8u261, the JSSE framework passed an array of Strings of all keytypes in one call to the (delegate) javax.net.ssl.X509KeyManager.chooseClientAlias(String keyType, Principal issuers, Socket socket) implementation when client authentication is present in an application. Since JDK 8u261, the internal JDK libraries may call the delegate javax.net.ssl.X509KeyManager.chooseClientAlias method in multiple iterations while performing client authentication. One key type per call. -java.lang.String:A-java.security.Principal:A-java.net.Socket-
Cause: One possible cause is old server intolerance to FFDHE arguments. As per TLS RFC 7919 on server behavior If a compatible TLS server receives a Supported Groups extension from a client that includes any FFDHE group (i.e., any codepoint between 256 and 511, inclusive, even if unknown to the server), and if none of the client-proposed FFDHE groups are known and acceptable to the server, then the server MUST NOT select an FFDHE cipher suite. In this case, the server SHOULD select an acceptable non-FFDHE cipher suite from the client's offered list. If the extension is present with FFDHE groups, none of the client's offered groups are acceptable by the server, and none of the client's proposed non-FFDHE cipher suites are acceptable to the server, the server MUST end the connection with a fatal TLS alert of type insufficient_security(71).
Cause: In case of an SSL abbreviated handshake (session resumption) SSL client is adding extra extensions than the agreed protocol's supported extensions. While it is TLS RFC complaint, some old non-compliant server implementations may reject this ClientHello.
BoringSSL is an SSL library deployed on some popular websites such as those run by Google/YouTube. An interoperability issue with the BoringSSL library can lead to a connection failure if TLSv1.3 is presented as the only enabled protocol in the ClientHello message and the certificate status_request extension is disabled. Enabling the certificate status_request extension by setting the jdk.tls.client.enableStatusRequestExtension system property to true will provide mitigation in such scenarios.
There is a risk of breaking Java Access Bridge functionality when installing Java on a Windows system that has both a previously installed version of Java and an instance of JAWS running. After rebooting, the system can be left without the WindowsAccessBridge-64.dll in either the system directory (C:\Windows\System32) for 64bit Java products or the system directory used by WOW64 (C:\Windows\SysWoW64) for 32bit Java products.
The system property jdk.tls.client.cipherSuites can be used to customize the default enabled cipher suites for the client side of SSL/TLS connections. In a similar way, the system property jdk.tls.server.cipherSuites can be used for customization on the server side.
The specification of javax.crypto.CipherInputStream has been clarified to indicate that this class may catch BadPaddingException and other exceptions thrown by failed integrity checks during decryption. These exceptions are not re-thrown, so the client may not be informed that integrity checks failed. Because of this behavior, this class may not be suitable for use with decryption in an authenticated mode of operation (e.g. GCM). Applications that require authenticated encryption can use the Cipher API directly as an alternative to using this class.
The specification of javax.crypto.CipherOutputStream has been clarified to indicate that this class catches BadPaddingException and other exceptions thrown by failed integrity checks during decryption. These exceptions are not re-thrown, so the client is not informed that integrity checks have failed. Because of this behavior, this class may not be suitable for use with decryption in an authenticated mode of operation (for example, GCM) if the application requires explicit notification when authentication fails. These applications can use the Cipher API directly as an alternative to using this class.
This release disables server side HTTP-tunneled RMI connections by default. The previous behavior can be re-enabled after due consideration of any impact by setting the runtime property sun.rmi.server.disableIncomingHttp to false. Note that this should not be confused with the sun.rmi.server.disableHttp property, which disables HTTP-tunneling on the client side and is false by default.
The issue with this code is that it is unspecified how the provider should derive a secret key from the output of the Diffie-Hellman operation. There are several options for how this key derivation function can work, and each of these options has different security properties. For example, the key derivation function may bind the secret key to some information about the context or the parties involved in the key agreement. Without a clear specification of the behavior of this method, there is a risk that the key derivation function will not have some security property that is expected by the client. 350c69d7ab
