Signing with SHA2

Hello,
Is it possible to sign a document with SHA2 (instead sha1 which is the default?)

Is it possible to use pkcs11 instead of CSP? i.e to place an external signature?

Hi

I would take a look at this blog which details thorough sample code of hashing using Open XML SDK v2.0:

I'm not sure if SHA2 is supported - but I can't see why you couldn't simply use SHA256Managed instead of the blog's suggested SHA1Managed.

The reason is because Ms Word 2007 does not know how to validate SHA2, if you look at the list of predefined hash algorithms that appear in openXML SDK, then you will see that that it is not there

Yeah i think  it is possible to use pkcs11 instead of CSP?

You can use pkcs11 if you really want to..
However OpenXML SDK won't let you do this, so you should do it directly instead.

Does Office 2010 support SHA2? When signing on a document from the Word/Excel application by adding a signature line, one can not choose a digest algorithm...
