Infopath Digital Signature

Briefly about digital signatures

You can enable digital signatures when designing a form so that users can add digital signature when filling it out. This digital signature proves that the form originated from the signer and has not been changed. Also the signature can include some comments from the author. After signing, the data in the form cannot be changed without cancellation digital signature.

When adding a digital signature, the user must use a digital certificate. Digital certificate is an attachment for a file, macro project, or e-mail message that assures authenticity, provides secure encryption, or supplies a verifiable signature. Digital certificates, which you can get through commercial certification authorities or from your internal security administrator, establish the authenticity of the signature.

About InfoPath digital signatures

In addition to enabling digital signatures so that users can sign your form, you can add a digital signature to your form template which authenticates you as the author of the form template in the same way that a digital signature on a form authenticates the user who filled out the form. Form template in InfoPath is a file or set of files that defines the data structure, appearance, and behavior of a form. For example, form templates that have been distributed to users in an e-mail message can be updated more effectively if they have been supplied with a digital signature.
When you put a digital signature in a form, InfoPath uses only those certificates that have a private key and a Digital Signature or Both value for the Key Usage attribute. Also the purpose of the certificate must be set as Client Authentication or Code Signing. If you are using a certificate to add digital signature to a form template, the certificate must be set as Code Signing. These limitations are applied because InfoPath uses XML Signatures to digitally sign forms.

• Because a digital certificate you create is not issued by a formal certification authority, forms signed using a certificate you created are referred to as self-signed forms. These certificates are considered unauthenticated and will generate a security warning if the form's security level is set to Domain. InfoPath trusts self-signed certificates only on computers that have access to the private key for that certificate. In most cases, this means that InfoPath trusts self-signed certificates only on the computer that created the certificate, unless the private key is shared with other computers.

• The information in this topic may not apply if you are working with a form designed using Microsoft Office InfoPath 2003 without the service pack installed.

Digital Signature for Office 2007

Microsoft Office 2007 provides many improvements in security in comparison with its predecessors. And one of new functions is possibility of digital signature of documents. Signing a document, you confirm that you are the creator of document, and it will prove that a document wasn't changed since you created its creation.

You can create a digital signature for a document because of the same amount of reasons, on which you can affix your signature to a paper document. A digital signature is used for identification of digital documents creator (such as ordinary document, e-mail and macros) by cryptographic algorithms.
Digital signatures are based on digital certificates. Digital certificates are verifiers of identity issued by a trusted third party, called a certification authority (or CA). This works similarly to the use of standard identity documents in the non-electronic world. For example, a trusted third party such as a government entity or employer issues identity documents such as driver’s licenses, passports and employee ID cards on which others rely to verify that a person is whom he/she claims to be.

Digital certificates can be issued by certification authorities within an organization, such as a Windows® Server 2003 server running Windows Certificate Services, or a public certification authority such as VeriSign or Thawte.

Microsoft 2007 Office system documents can have invisible signatures or signatures lines added to them. When used together with other Microsoft 2007 Office system security technologies and security technologies included in the Microsoft Office Servers and Windows operating system, digital signatures provide another significant component of a strong defense in depth approach to security data stored in Microsoft 2007 Office system documents, workbooks and presentations.

VBA Digital Signature

Digital Signature for VBA Project

Once you have your digital certificate installed, you can sign the VBA projects associated with Word, Excel, and PowerPoint documents, templates, and add-ins. For Outlook, you can sign the VBA project that is associated with the installation of Outlook on a particular computer. Any time code in a signed VBA project is modified in any way, its digital signature is removed. However, modifying the contents of the document other than the VBA code won't invalidate the signature on a VBA project contained within the document. This is because only the VBA project is signed, not the entire document.
If you want to prevent users of your solution from accidentally modifying your VBA code and invalidating your signature, lock the VBA project before signing it. Locking your VBA project doesn't prevent another user from replacing the with another digital signature. This is allowed so that a system administrator or end user can replace a current signature with an approved signature or re-sign a document after a previous signature expires.
Similarly, if you produce an add-in that adds code to a document's VBA project, your code should determine if the project is digitally signed and notify the user of the consequences of modifying a signed VBA project before continuing.

VBA Digital Signature - How to sign VBA projects

You create digital signature for VBA (Visual Basic for Applications) project by using a digital certificate.
If you don't already have a digital certificate, you must obtain one.
You can obtain a digital certificate from a commercial certification authority, such as VeriSign, Inc., or from your internal security administrator or Information Technology (IT) professional. Or, you can create a digital signature yourself by using the Selfcert.exe tool.
Because a digital certificate you create yourself isn't issued by a formal certification authority, VBA projects signed by using such a certificate are referred to as self-signed projects. Depending on how Microsoft Office digital-signature features are being used in your organization, you might be prevented from using such a certificate, and other users might not be able to run self-signed macros for security reasons.

Verisign Digital Signature

Digital Signatures became available as one of the AutoCAD extensions, part of the Autodesk Subscription program.

Verisign Digital Signature - How to Get

First of all, you need to get a digital signature. There are numerous certificate authorities that are happy to take your money and give you a digital signature -in fact, most of them offer a free trial option. Autodesk uses a company called Verisign as its digital-signature provider, but it isn't mandatory that you use them. The first time you launch the Digital Signature program, you will be sent to Verisign to get a digital signature (unless you already have one). There are different types of digital signatures depending on the level of security you need. If you want a digital signature that prompts for a password every time you use it, you'll have to pay more. You can even get a minimum-security signature on a 60-day trial basis for free, which I recommend until you decide you're completely sold on the digital-signature concept. When you're ready to make the commitment, you'll find you can get a digital signature for a year for $15.95. Digital signatures are stored in the REG file.

I found it very painful trying to move my digital signature from one computer to the next when I upgraded my laptop. I couldn't even buy another one because it was linked to my email address and Verisign kept telling me I already had a digital signature. After working with the Verisign customer service (and a few gray hairs later), I was finally able to figure out how to move it. Just a heads-up here!

Each digital signature ID is unique and is made up of a name, serial number, and an expiration date, along with other assorted information. Once you get your digital signature ID, AutoCAD will remember that long ID.
