Data Digester XML Examples

This page shows some example for Digester XML files being an alternative to the functionally limited GNU or BSD files. The new Digester XML format provides support for multiple digests and algorithms together in one single file. Also OpenPGP signatures may be included together with checksums. Another interesting feature of the Digester XML format is the capability to store intermediate digests. Imagine a large backup file with a data error in the first blocks. This may be detected very fast using intermediate digests, there is no need to calculate the checksums for the whole file.

Please check out the current document type definition (DTD) summary-1.1.dtd specifying the Digester XML format.
