Package org.docx4j.org.apache.poi.poifs.crypt

Implementation of the ECMA-376 Document Encryption

The implementation is split into three packages:

• This package contains common functions for both current implemented cipher modes.
• the standard package is part of the base poi jar and contains classes for the standard encryption ...
• the agile package is part of the poi ooxml jar and the provides agile encryption support.
