There's a program called "lsar" that can print out all kinds of useful info about all kinds of archive formats, including MS Office files. Some encrypted office files contain a subfile called "EncryptionInfo" while for others, "lsar" issues an "XADIsEncrypted" attribute. So you can key off those. On Debian, "lsar" is part of the "unar" package.
