New system property to control caching for HTTP SPNEGO connection.ДЄ new JDK implementation specific system property to control caching for HTTP SPNEGO (Negotiate/Kerberos) connections is introduced.

Please periodically check the Oracle JRE and JDK Cryptographic Roadmap at for planned restrictions to signed JARs and other security components. Zip -d test.jar 'META-INF/.SF' 'META-INF/.RSA' 'META-INF/*.DSA' Before re-signing affected JARs, the existing signature(s) should be removed from the JAR file. Alternatively, the restrictions can be reverted by removing the applicable weak algorithms or key sizes from the security property however, this option is not recommended. To address the issue, the JAR file will need to be re-signed with a stronger algorithm or key size. Timestamp signature algorithm: SHA256withRSA, 2048-bit key Timestamped by 'CN=strong_tsa' on Mon Sep 26 08:59: Signature algorithm: MD5withRSA (weak), 512-bit key (weak) More details can be displayed by using the verbose option: Re-run jarsigner with the -verbose option for more details. The jar will be treated as unsigned, because it is signed with a weak algorithm that is now disabled. If the file in this example was signed with a weak signature algorithm like MD5withRSA, the following output would be displayed: Running 'jarsigner -verify' on a JAR file signed with a weak algorithm or key will print more information about the disabled algorithm or key.ДЇor example, to check a JAR file named test.jar, use the following command: To check if a weak algorithm or key was used to sign a JAR file, one can use the jarsigner binary that ships with this JDK. This property contains a list of disabled algorithms and key sizes for cryptographically signed JAR files. The list of disabled algorithms is controlled via the security property,, in the curity file.

Standalone or Server Applications that are run with a SecurityManager enabled and are configured with a policy file that grants permissions based on the code signer(s) of the JAR file.

This can potentially occur in the following types of applications that use signed JAR files:

#JAVA 8 101 VERIFICATION#

If the signed JAR file uses MD5, signature verification operations will ignore the signature and treat the JAR as if it were unsigned. This JDK release introduces a new restriction on how MD5 signed JAR files are verified. De release notes voor deze uitgave zien er als volgt uit: Changes security-libs/curity

#JAVA 8 101 UPDATE#

Naast de versie voor gewone computers is de update ook verkrijgbaar voor embedded systemen. Oracle heeft een update voor versie 8 van zowel de developmentkit als de runtime-environment van Java Standard Edition uitgebracht.
