Package org.apache.poi.poifs.crypt Description

Implementation of the ECMA-376 and MS-propritary document encryptions

The implementation is split into the following packages:

This package contains common functions for both current implemented cipher modes.
the agile package is part of the poi ooxml jar and the provides agile encryption support.
the binaryrc package is used for the fixed length RC4 encryption of biff/H**F formats
the cryptoapi package is used for the variable length RC encryption of biff/H**F formats
the standard package contains classes for the standard encryption ...
the xor package contains classes for the xor obfuscation of biff/H**F formats
