Java Security Tweaks

Algorithm constraints check failed: MD5withRSA

Newer versions of Java require an SSL key length of at least 1024, however older apps may not provide that long of a key.

Here, we edit $JAVA_HOME/jre/lib/security/java.security to reduce the requirement to 512.

Change 1024 to 512, 256 or 128 as necessary:

jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024

to

jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 512
