Digital signature of a PDF document requires using a digital certificate X.509. It is a file issued to your name, notary-commissioned name, by a technology company that maintains a public repository to check the validity of your certificate, and you have it as a .pfx file. A digital certificate must be validated by checking its status in a publicly available OCSP server to verify its validity. Your device must be connected to the internet for the validation.
As you have selected a PDF file and the digital certificate to it to make it tamper-evident, the last step is to sign and save. Please remember that after you sign and save, there will be no further changes to the document. It is your last action on the file. The signing is happening on your device, and no data is transmitted outside of your device. After you save the new document that was digitally signed, it is your responsibility to transfer and save it.
If you are a proud owner of a PC (Windows-based computer) or a Mac, not an iPad or iPhone, please use Adobe Acrobat Reader.
