What problem are you trying to solve? Do you want encryption between server
and client, between servers or encryption of data within Hbase? You need to
be more specific.

If one of the first two is what you want: This kind of stuff can easily be
achieved with stunnel or OpenVPN and can probably be considered a very
esoteric requirement, as there are probably not many Hbase users out there,
who have a cluster running across machines that are exposed to open
networks.
If you are looking for the latter, imo the correct way to do it would be
encrypting data _before_ pushing it into the database. Java actually
provides an excellent crypto framework for doing such things.

Hi there
I want encryption before pushing data into hbase,and I've done it by
changing in some library to encrypt data.But it doesn't have any
performance,I mean for each row it should encrypt/decrypt the cell,so for a
query that has a lot of rows ,it will take a long time.
my question is this,why hbase doesn't have any option for that ( in hbase
shell like compression method ),for example like other relational
databases(sqlserver,.. ),is there any reason for that ?
 Thanks you guys

How else would you see it working? (We can't do a row at a time given
our architecture)

No reason.  No one has really asked for it in the past, or more
importantly, no one has posted a patch that provides it.

Tnx Stack for giving your time to me.
