Of course, for larger chunks of data, a BLOB or similar might be a
better choice. ;-)

When I've run into this problem, I've taken the brute-force, it may
not be the most efficient but it'll work, approach of converting the
byte[] into a hex string, and storing this. It doubles the storage
required (2 chars per byte), so it depends on the data requirements if
it's the right answer for you. But you're pretty much guaranteed to
get back from the db what you stored. The nice thing is you can
implement it in your accessor methods and never worry about it again.

I've successfully implemented the javax.crypto.spec.PBEKeySpec
(password-based encryption) for encrypting key information in my
database. I can encrypt and decrypt with ease now. But wait! I can't
seem to figure out how to store this marvelously encrypted info.
The PBEKeySpec pbeCipher.doFinal() generates a byte[] array, each
byte being a hex value. In any attempt I have made in storing this to
the database, WO converts it to a string and gets very unpredictable
results due to the conversion to non-printable characters.
How is this normally done so it can be store and, importantly,
retrieved in a form that can be converted back?
