SwitchExplorer for Brocade FC switches no longer works properly on more recent versions of Java, because of security constraints. They can, however, be relaxed so you can still access your switches.

1. Browse for the installation location for your JRE, and look for the folder lib/security (note: differentiate between 32 and 64-bit on Windows).
2. Open the file java.security, and look for the line:

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

3. Change the 1024 to 256, and save.

Note for Windows Vista and up: open the file elevated, or you won't be able to save it.
