Specifying a streaming cipher for data encryption causes
java.lang.ArithmeticException
--------------------------------------------------------------------------------------
Key: DERBY-2552
URL: https://issues.apache.org/jira/browse/DERBY-2552
Project: Derby
Issue Type: Bug
Components: Services
Affects Versions: 10.3.0.0
Reporter: Kristian Waagan
If a streaming cipher is specified for data encryption when creating a
database, a java.lang.ArithmeticException is thrown.
The reason is that the cipher block size is used in a division as the divisor
and it has value 0 (zero).
Derby should either inform that streaming ciphers are not supported, or be able
to use them.
A quick hack indicates Derby is capable of using streaming ciphers. I was able
to create an encrypted database using the ARCFOUR (RC4) algorithm, close Derby
and boot the database and fetch the data in the database again. This required
changes in only two places (LogToFile and FileLogger), but the issue must be
further investigated.
