sign
Applies an invisible digital signature to a document. An invisible signature adds cryptographic proof of authenticity without any visual representation on the document pages. The signature can be verified in PDF viewers that support digital signatures. If the document is not in PDF format and implicit conversion is enabled in the document settings, it will be automatically converted to PDF before signing. If the document was opened with a password through its open settings, that password is applied automatically so password-protected PDFs can be signed.
Parameters

The path where the signed PDF will be saved.
