Add Document Password Leave feedback

GroupDocs.Merger for Python via .NET lets you add an open password to any supported document format. Once protected, the document can only be opened by users who supply the correct password.

1. Instantiate the Merger class with the path to the source document.
2. Create an AddPasswordOptions instance with the desired password string.
3. Call merger.add_password() and pass the AddPasswordOptions object.
4. Call merger.save() with the output file path to write the protected document.

from groupdocs.merger import Merger
from groupdocs.merger.domain.options import AddPasswordOptions

def add_document_password():
    # Load the source document
    with Merger("./input.pdf") as merger:
        # Define the password to apply
        options = AddPasswordOptions("p@ss")
        # Encrypt the document with the specified password
        merger.add_password(options)
        # Save the password-protected document
        merger.save("./output.pdf")

if __name__ == "__main__":
    add_document_password()
