Keith Turner commented on ACCUMULO-958:
---------------------------------------

I will take a look at reverting in 1.5.  We can work on getting this in for 1.6.   I want to give the new patch a thorough review, I will do that in the next few days.   I took a quick glance at and I think I noticed a few chunks of commented out code being added.  I would recommend dropping those.

> 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.
