Subject Re: How to configure internode encryption in 0.8.0?
Date Wed, 18 May 2011 00:47:32 GMT
Thanks for the link, Jeremy.

I generated the keystore and truststore for inter-node communication using
the link in the YAML file:
http://download.oracle.com/javase/6/docs/technotes/guides/security/jsse/JSSERefGuide.html#CreateKeystore

<http://download.oracle.com/javase/6/docs/technotes/guides/security/jsse/JSSERefGuide.html#CreateKeystore>Unfortunately,
the default instructions in the above link
used TLS_RSA_WITH_AES_256_CBC_SHA. So, when I start Cassandra now, I get
this error:

ERROR 00:10:38,734 Exception encountered during startup.
java.lang.IllegalArgumentException: Cannot support
TLS_RSA_WITH_AES_256_CBC_SHA       with currently installed providers
        at
com.sun.net.ssl.internal.ssl.CipherSuiteList.<init>(CipherSuiteList.j
 ava:79)
        at
com.sun.net.ssl.internal.ssl.SSLServerSocketImpl.setEnabledCipherSuit
 es(SSLServerSocketImpl.java:166)
        at
org.apache.cassandra.security.SSLFactory.getServerSocket(SSLFactory.j
 ava:55)


The YAML file states that the cipher suite for authentication should
be: TLS_RSA_WITH_AES_128_CBC_SHA.

This is my first time using keytool and I've searched the web to see how I
can change the cipher from AES_256 to AES_128, but haven't found the answer.

Anyone know how to change the cipher to AES_128?

Here are the commands I used to generate the non-working keystore and
truststore:

1) keytool -genkeypair -alias jdoe -keyalg RSA -validity 7 -keystore
.keystore
2) keytool -list -v -keystore .keystore
3) keytool -export -alias jdoe -keystore .keystore -rfc -file jdoe.cer
4) cat jdoe.cer
5) keytool -import -alias jdoecert -file jdoe.cer -keystore .truststore
6) keytool -list -v -keystore .truststore
