Does PDF&#47A support digital signatures?

Yes. PDF&#47A allows the use of digital signatures embedded in PDF as defined in the PDF Reference Manual. Because PDF digital signatures include a visual appearance, the appearance must conform to all the requirements of PDF&#47A including font embedding and use of device independent color. Not all commercial digital signatures tools follow these requirements. The Adobe Professional application can be used to digitally sign a PDF/A file.
