Adam Fuchs commented on ACCUMULO-958:
-------------------------------------
This is really just half of a bigger story, which is half of the encryption at
rest epic for Accumulo. The other small half is RFile encryption, and the other
big half is key distribution. The end goal is definitely to have users be able
to just turn on encryption. We're trying to make sure that all the necessary
extension points are in place before 1.5 is released.
> Support pluggable encryption in walogs

> URL: https://issues.apache.org/jira/browse/ACCUMULO-958
> Project: Accumulo
> Issue Type: Improvement
> Components: logger
> Reporter: John Vines
> Assignee: John Vines
> Fix For: 1.5.0
>
>
> There are some cases where users want encryption at rest for the walogs. It
> should be fairly trivial to implement it in such a way to insert a
> CipherOutputStream into the data path (defaulting to using a NullCipher) and
> then making the Cipher pluggable to users can insert the appropriate
> mechanisms for their use case.
> This also means swapping in CipherInputStream and putting in a check to make
> sure the Cipher type's match at read and write time. Possibly a versioning
> mechanism so people can migrate Ciphers.
