Adding Signatures to PDFs
Java Developers can add electronic and digital signatures to PDF documents programmatically using IronPDF for Java's Signature and SignatureManager classes.
For digital signatures, instantiate a new Signature class with the location of a valid
.p12 certifcate, along with its password. Next, call the signPdfWithSignature method on the working PDF's
SignatureManager to sign the PDF with the certificate.
IronPDF also supports inclusion of signature images, in the form of computer-generated text images or digitized images of handwriting. Add such images to a signature with the addSignatureImage method prior to signing the PDF.
Need to add a handwritten signature on a PDF page instead? Use the HtmlStamper class to add HTML text and images to one or more pages of a document.
