# Punch Certs for Web-Based IPMI (on a Mac)

Web-Based access to IPMI on SuperMicros gives Java security exceptions, a joke in itself.  How to disable?

```
cd /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/lib/security/
```

edit java.security and remove MD5 from

```
jdk.certpath.disabledAlgorithms=MD2, MD5, RSA keySize < 1024
```

and remove MD5withRSA

```
jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 768
```
