Today I was playing around a little with apache cassandra, setting up internode encryption with keystore and truststore, following the tutorial in the cassandra.yaml file. But I always ended up getting the error message: Cannot support TLS_RSA_WITH_AES_256_CBC_SHA with currently installed providers.

How to fix this Error

Full error message

Solution

Note: I’m using jre6 on Debian Squeeze and jre7 on Windows 7 64-bit, it may differ on other distributions or operating systems

This error message has to do with missing or corrupt java security libraries.
