[ http://tools.oasis-open.org/issues/browse/OFFICE-2656?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Brauer updated OFFICE-2656:
-----------------------------------

    Resolution: 
Add to Section 4.2 <dsig:document-signatures>:

If a digital signature file is not encrypted, consumers shall not decrypt files that are referenced by <Reference> elements and that are encrypted before validating the signature.
If a digital signature file is encrypted, consumers shall decrypt files that are referenced by <Reference> elements and that are encrypted before validating the signature.


> Clarify when signatures operate on encrypted and when on unencrypted files.

> The ODF 1.2 part 3 CD01 specification currently does not explicitly state how references to encrypted files are handled.
> There are two uses cases:
> a) A signature is applied to an encrypted document. In this case, the signature would operate on the encrypted files.
> b) A signed document is encrypted. In this case, the signature would operate on the unencrypted files.
