Subject Database encryption
Date Wed, 18 Nov 2009 07:16:43 GMT
Hi all,

I use the derby database encryption frequently in my programs but I was
wondering how it really works.

Does it decrypt the db once on boot and then once more time on shutdown only
?
or does the database stay encrypted all the time and the data that goes back
and forth is encrypted/decrypted on the fly ?

One more question whose answer is not in the derby docs, when I specify an
encryption key in the jdbc url and I do not specify the
"encryptionKeyLength" parameter, what does it take as default value?
supposed I was using AES or Blowfish which can use 192 or 256bit keys, does
derby automatically guess the key length from the specified key?

Thanks.
