Kristian Waagan updated DERBY-1740:
-----------------------------------
Attachment: derby-1740-1a.diff
The patch 'derby-1740-1a.diff' is a *draft* patch. I would like some feedback
on it.
Is it a viable solution to the problem?
The error message contains two integers describing the length of the external
encryption key. But what unit should be used? The external encryption key is a
hexadecimal string generated by a utility method in Derby, where a byte is
split into a high and a low nibble.
A password of 8 characters, would result in an encryption key of length 16
[units] (if converted/processed by Derby). Is it okay to use characters as the
unit?
I have only tested the patch with the repro, it is not ready for commit.
