eSign Word Processing document with Metadata signature Leave feedback

GroupDocs.Signature provides WordProcessingMetadataSignature class to specify different Metadata signature objects for MetadataSignOptions instance to sign Word Processing document files. Word Processing document metadata is hidden attributes, some of them are visible only over viewing standard document properties like Author, Creation Date, Producer, Entry, Keywords etc.
Word Processing document metadata contains pair of Name and Value, Name should be unique within the document.
Word Processing document metadata could keep big amount of data that allows provides ability to keep serialized custom objects with additional encryption in there.

• Create new instance of Signature class and pass source document path as a constructor parameter.
• Instantiate the MetadataSignOptions object according to your requirements.
• Instantiate one or several WordProcessingMetadataSignature objects and add them to the signatures collection of MetadataSignOptions with the append or add_range method.
• Call Sign method of Signature class instance and pass MetadataSignOptions to it.

This example shows how to sign Word Processing document with Metadata e-signature.

from datetime import datetime

from groupdocs.signature import Signature
from groupdocs.signature.options import MetadataSignOptions
from groupdocs.signature.domain import WordProcessingMetadataSignature


def sign_docx():
    with Signature("sample.docx") as signature:
        options = MetadataSignOptions()

        # Create a few Word Processing Metadata signatures
        signatures = [
            WordProcessingMetadataSignature("Author", "Mr.Scherlock Holmes"),
            WordProcessingMetadataSignature("DateCreated", datetime.now()),
            WordProcessingMetadataSignature("DocumentId", 123456),
            WordProcessingMetadataSignature("SignatureId", 123.456),
        ]

        # Add them to the options
        options.signatures.add_range(signatures)

        # Sign the document and save the result
        result = signature.sign("signed.docx", options)
        print(f"Signed with {len(result.succeeded)} metadata signature(s):")
        for item in result.succeeded:
            print(f"  {item.name}")


if __name__ == "__main__":
    sign_docx()
