Calculates checksums for specified data.

Parameters:

data - The content for which to calculate checksums, must not be null.

factories - The checksum algorithm factories to use, must not be null.

Returns:

The calculated checksums, indexed by algorithm name, or the exception that occurred while trying to calculate it, never null.

Throws:

java.io.IOException - In case of any problem.
