[jira] [Commented] (CASSANDRA-3278) SSLFactory should not enable
cipher suites that aren't supported
[ https://issues.apache.org/jira/browse/CASSANDRA-3278?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13158789#comment-13158789 ]
Brandon Williams commented on CASSANDRA-3278:
---------------------------------------------
This looks good, but one minor nit: instead of cipherSuites in the yaml can we use the more idiomatic 'cipher_suites'?

> 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.
