Release Note: Disabled All DES TLS Cipher Suites

      Description

        DES-based TLS cipher suites are considered obsolete and should no longer be used. DES-based cipher suites have been deactivated by default in the SunJSSE implementation by adding the "DES" identifier to the `jdk.tls.disabledAlgorithms` security property. These cipher suites can be reactivated by removing "DES" from the `jdk.tls.disabledAlgorithms` security property in the `java.security` file or by dynamically calling the `Security.setProperty()` method. In both cases re-enabling DES must be followed by adding DES-based cipher suites to the enabled cipher suite list using the `SSLSocket.setEnabledCipherSuites()` or `SSLEngine.setEnabledCipherSuites()` methods.

        Note that prior to this change, DES40_CBC (but not all DES) suites were disabled via the `jdk.tls.disabledAlgorithms` security property.
