A set of protocols support a common script object model for document interaction that crosses document types and runtime environments. A cross frame browser-based protocol may provide a secure, scalable, and asynchronous mechanism for transmitting script object model requests to document hosts and managing responses to developer code in standards-compliant browsers. A hostable runtime Application Programming Interface (API) may provide a secure, scalable, and asynchronous protocol to transmit script object model requests across process boundaries to document hosts back to developer code with minimum performance impact on the document host.

Document communication runtime interfaces

A software tool for digitally signing multiple documents is disclosed. When a user wishes to sign multiple documents containing embedded executable code for purposes of authenticating the code, the user launches this software tool. The user specifies the documents which he or she wishes signed. Thereupon, the tool automatically signs each of the documents and displays the results.

Tool for digitally signing multiple documents

Techniques are provided for forming a digital signature for a portion of a document. A registered module is invoked to process the document in accordance with a structured format associated with the document. The registered module is able to process a plurality of different structured formats. The registered module obtains the portion. A digital signature is formed for the portion. The digital signature is included in the document in accordance with the structured format.

Techniques for digital signature formation and verification

Generating a digital signature of an entire embedded code project is provided while maintaining certain exclusion areas so that a productivity application can incorporate application-specific information into the embedded code project without hampering the digital signature. A tree structure of data may be serialized into a data stream. The tree structure may include multiple branches and one or more elements identified as an exclusion area. A digital signature of the data stream may be created and included in a document associated with the tree structure.
