SSLFactory should not enable cipher suites that aren't supported
----------------------------------------------------------------
Key: CASSANDRA-3278
URL: https://issues.apache.org/jira/browse/CASSANDRA-3278
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 0.8.6, 0.8.5, 0.8.4, 1.0.0
Environment: OpenJDK on debian squeeze
Reporter: George Cristea
Priority: Minor
The socket creation (server or otherwise) in SSLFactory.java calls
[setEnabledCipherSuites|http://download.oracle.com/javase/6/docs/api/javax/net/ssl/SSLServerSocket.html#setEnabledCipherSuites(java.lang.String\[\])]
with the values specified in EncryptionOptions.java:
{code}
public String[] cipherSuites = {
"TLS_RSA_WITH_AES_128_CBC_SHA",
"TLS_RSA_WITH_AES_256_CBC_SHA"
};
{code}
The call to
[setEnabledCipherSuites|http://download.oracle.com/javase/6/docs/api/javax/net/ssl/SSLServerSocket.html#setEnabledCipherSuites(java.lang.String\[\])]
fails on systems that don't have [Java Cryptography Extension (JCE) Unlimited
Strength Jurisdiction Policy Files
6|http://www.oracle.com/technetwork/java/javase/downloads/jce-6-download-429243.html]
because AES256 is not supported.
To avoid installing the unlimited strength policy file the code in
SSLFactory.java should call
[getSupportedCipherSuites|http://download.oracle.com/javase/6/docs/api/javax/net/ssl/SSLServerSocket.html#getSupportedCipherSuites()]
to find out which of the suites specified are supported.
Thanks,
George
