Subject [jira] [Commented] (CASSANDRA-6018) Add option to encrypt commitlog
Date Tue, 12 Jan 2016 15:26:40 GMT


Branimir Lambov commented on CASSANDRA-6018:

bq. While there's prossibly some improvements that can be taken into account, ...

Sounds good. Could {{encrypt}} be renamed to {{encryptAndWrite}} to make obvious what it does?

I believe the || in [catching {{SegmentReadException}}|]
should be an &&: invalid CRC is not tolerated even in the last segment.

The {{ReadCommandTest}} failures should disappear once you rebase to latest trunk.

> We are going to start using cassandra for a billing system, and while I can encrypt sstables
at rest (via Datastax Enterprise), commit logs are more or less plain text. Thus, an attacker
would be able to easily read, for example, credit card numbers in the clear text commit log
(if the calling app does not encrypt the data itself before sending it to cassandra).
> I want to allow the option of encrypting the commit logs, most likely controlled by a
property in the yaml.
