Kim Haase updated DERBY-5550:
-----------------------------
Attachment: DERBY-5550.zip
DERBY-5550.stat
DERBY-5550.diff
Thanks very much, Knut, for the quick reply!
I'm attaching DERBY-5550.diff, DERBY-5550.stat, and DERBY-5550.zip, with
changes as follows:
M src/ref/crefproper22250.dita
A src/ref/rrefproperiterations.dita
A src/ref/rrefpropersaltlength.dita
M src/ref/refderby.ditamap
M src/devguide/rdevcsecure557.dita
M src/devguide/cdevcsecurenativeauth.dita
In addition to adding topics for the two new properties, I added them to the
table of properties in the Reference Manual and, in the Developer's Guide,
added mentions of them to the NATIVE authentication topic and the list of
authentication-related properties.
Please let me know of any changes that are needed. There might also be other
topics that should mention these properties. Thanks again!

> DERBY-5539 introduced two new properties that control how BUILTIN stores
> credentials:
> - derby.authentication.builtin.saltLength (default: 16)
> This property specifies the number of bytes of random salt that will be added
> to the credentials before hashing them. (Purpose of the property: Make it
> infeasible to construct rainbow tables.)
> - derby.authentication.builtin.iterations (default: 1000, minimum: 1)
> This property specifies the number of times to apply the hash function (which
> is specified by derby.authentication.builtin.algorithm) on the credentials.
> (Purpose of the property: Slow down attackers as they'll need to spend more
> time calculating hashes.)
> Both the properties have effect only if BUILTIN authentication is enabled and
> derby.authentication.builtin.algorithm has a non-null value.
