Subject [jira] [Updated] (DERBY-4229) encryptionKeyLength connection attribute should be documented
Date Thu, 01 Nov 2012 19:05:13 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4229?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kathey Marsden updated DERBY-4229:
----------------------------------

    Fix Version/s:     (was: 10.5.2.0)

Removing 10.5.2.0 as the issue was fixed in 10.5.3.1. I think it causes the issue to not show
up in the release notes (just guessing)

> The developer guide says:
> The length of the encryption key depends on the algorithm used:
> AES (128, 192, and 256 bits) 
> DES (the default) (56 bits) 
> DESede (168 bits) 
> All other algorithms (128 bits) 
> Note: The boot password should have at least as many characters as number of bytes in
the encryption key (56 bits=8 bytes, 168 bits=24 bytes, 128 bits=16 bytes). The minimum number
of characters for the boot password allowed by Derby is eight.
> For AES, however,  it does not tell how to change the default key length  of 128.  This
can be changed with the encryptionKeyLength connection attribute.  The documentation should
also specify that special policy files for the JRE may be necessary to accomodate the longer
length.
> Also note that there is an outstanding issue DERBY-3710 regarding length of 192 for AES.
