How to bypassing Java Expired Certificate check to Brocade Switches;
Problem;
Java Error: Failed to validate certificate. The application will not be executed
A detailed look into the certificate shows that a signature algorithm MD2withRSA was used to create it.
Java Certificate error
Java certificate details
Solve;
MD2 is disabled in java by default also a RSA key with less then 1024bits. Because these are no longer considered as secure and therefore java reject such certificates.
You can disable this check, because you have start the applet to access your FC Switch. Locate the file java.security in the lib/security folder of your java installation and comment the following:
# jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024
The applet should start now but for security reasons it is recommended to reverse this change if it is no longer needed.
I had success by change the jdk.certpath.disabledAlgorithms located in \Java\jre7\lib\security\java.security from
Then only I was able to by allowed to bypass that certificate error :))
