Michael Allen commented on ACCUMULO-958:
----------------------------------------
Hi all, I'll take on getting this code up to snuff and responding to everyone's
thoughtful comments. The areas I'll be concentrating on besides basic cleanups
will be in the tidiness around the parameters and in getting some basic tests
completed. Thanks again for the thoughts, we'll get this in better shape
before release.
> Support pluggable encryption in walogs

> 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.
