Hello Peter,
hello George,
thank you for your 2 mails. And sorry I didn't reply earlier.
Yes, I also realized that there is no difference between the embedded and the
standalone version.
The only exception is that you have to put the encryption library in the
CLASSPATH of the network server if you want to use one.
Everything else can be passed to the database via the connection.
About SSL: As I use it as a local database, but in a different process than
then application (this way I can do some maintenance even independent from the
application) I guess I don't need it.
Or let's put it this way: If a person is already on the machine and would be
able to sniff the local IP traffic, that person may also have access on the
files of Derby.
And somewhere there is also the password for the keystore as well as the path
to the keystore which contains the certificate(s). I guess from there to the
boot password it is only a short way.
Or I'm wrong?
For a database installed on a different machine I definitely would recommend
using SSL, of course.
Thanks for your mails again. :-)
Gruß
Gerrit

Betreff: Re: Use Apache Derby Network Server with encrypted database
Hi Gerrit,
Based on Apache Derby page, between the embedded mode and network mode there is
no difference,
https://db.apache.org/derby/docs/10.0/manuals/admin/hubprnt19.html#Differences+between+running+Derby+in+embedded+mode+and+using+the+Network+Server
Have you tried to create an encrypted database via the network mode using the
steps mentioned in your link ? It should work, otherwise can you please post
your errors/stacktrace/exceptions.
What I did on my side to try your scenario :
1. Start Apache Derby in network mode
2. Create a dummy encrypted database and connect to it via ij:
a. connect
'jdbc:derby://localhost:1527/MyDbTest;create=true;dataEncryption=true';
3. After that I’ve started to create tables and to execute SQL queries
(select), just to play with the database.
4. It worked, no difference between embedded vs network mode.
a. Remember to append to the URL the host and the port where
Apache Derby server is started ( in my case it was localhost : 1527).
What I’ve followed in order to achieve the above:
1. http://db.apache.org/derby/papers/DerbyTut/ns_intro.html#ij_ns_client
2. http://db.apache.org/derby/papers/DerbyTut/ij_intro.html#ij_connect
3. https://db.apache.org/derby/docs/10.0/manuals/develop/develop15.html
4. If you want a more custom example regarding the algorithm that can be
used to encrypt the database, please have a look into this page :
a.
https://db.apache.org/derby/docs/10.2/ref/rrefattribencryptkey.html
If you need more information, please let me know.
Regards,
George

Betreff: Re: Use Apache Derby Network Server with encrypted database
Dear Gerrit,
from my understanding the only difference with Derby network server and
embedded is relevant part of connection string. The rest where you put
parameters after semicolon and where you would specify encryption properties is
the same. Just start network server and then connect using network url with
decryption parameters, subsequent connections should also use those parameters
because you do not know if database has already booted or not. I strongly
recommend using SSL to connect to encrypted database ;)

Hello everyone,
I've used Apache Derby for years now as an embedded RDBMS.
BTW: Thanks to all developer doing a great job developing this database system.
:-D
But now I want to use it as a separate service running on Ubuntu Linux.
This is no problem.
But I haven't found any explanation or example how to create and use encrypted
database if I'm running Derby as a service.
I found only this page:
https://db.apache.org/derby/docs/10.0/manuals/develop/develop115.html
But it seems it only deals with an embedded Derby version.
Regards,
Gerrit
