This article is an overview of digital signature practices and user considerations necessary to write applications in compliance with ISO/IEC 15408 Common Criteria security. Signing categories are described, including those that are a potential risk to the implied trust association that goes with a digital signature.

I have a whole bunch of forms contains errors like whenever you try to open it up.
Infopath cannot load this form. Either the signature is corrupted, or the certificatie used to sign this form is expired or revoked.
The forms were orginally created with digital signature with it. But we were in the middle of transition from one company to another company. The digital signature was
no longer valid. Actually, the certificate should have been expired by now. I removed all the signatures for all of the forms. So they can continue using the forms to fill in the information. The problem right now, is trying to
open the old forms with digital signature on it. Not only the company has changed. We also moved sharepoint from the old server to the new server.
Any idea to resolve th

What's the acrual problem ?
I am trying to compute a signature this way:
System.Security.Cryptography.Pkcs.ContentInfo contentInfo = new System.Security.Cryptography.Pkcs.ContentInfo(inputBytes);
SignedCms signedCms = new SignedCms(contentInfo);
CmsSigner cmsSigner = new CmsSigner(cert);
cmsSigner.DigestAlgorithm = new Oid("220.127.116.11.2.26");
byte enc = signedCms.Encode();
This works fine, because the Oid is for SHA1, but if I replace it with OID for SHA256:
it will wail with "Invalid algorithm specified".
We are using wse 2.0 sp2 and I recently installed a new webservice as windows service previously it worked fine but once I re-installed it as windows service it throws an error

I have an infopath form that uses digital signatures. The current process for the user is to:
1. click the "click here to sign this section" link.
2. click "select image", and browse to their image
3. click ok.
I've been requested to shorten the above to one click. So, it should sign the section (with their image) without prompting the user with the digital signature dialog.
Any suggestions? Is this even possible? As the capability to digitally sign a doc without the user knowing would seem to violate the idea of digital signatures...
This is for the InfoPath 07 client (which may mean that this is not in the correct forum(?))
I have problem to create digital signature. I created console application and it works there but when I want to run it at server there is exception. It looks like I have problem with reference to the file. Any idea please?
