These 4 files contain dde-links to calc.exe and are encrypted with
excel's standard password.

These are encrypted with the standard password hard-coded into excel to
implement a form of write protection

oleobj: detect external links

Samples were created by me using Office 2010 on a Windows 7 machine,
password is "encrypted", contents is trivial (no links, macros, ...)

Encryption should be the CryptoAPI RC4 Encryption (see [MS-OFFCRYPTO])

oleid: detect OpenXML encryption

The pre-read test found a bug in oleobj for zipped-xml files. Will fix with
next commit.

Will add excel test code and samples later, no need to have separate
folders for different file types.

The test documents supplied here may contain DDE links but these
only start calc.exe. No links to web pages there.
