Digital signatures use a complex unbreakable formula to seal a document and add information about the author.
Using jPDF Signer, you can easily create, sign and validate the PDF signatures embedded in a document. The product supports all Adobe standards (namely PKCS1 and PKCS7) along with the standards defined by Verisign.

You protect your documents when you turn to the industry standard for strong encryption AES and RC4.
When you use jPDF Signer, the document contents are sealed and cannot be stolen: All texts, fonts and graphics are ciphered to prevent unauthorized extractions.

Prevent Printing, Modification, Form filling, Merging, etc. based on user roles in your organization. Restrict document access by prompting readers to input a password or a certificate of identity. We offer the only product that has it all.

Do you need to work with a hardware signer such as a smartcard reader and/or a hardware accelerator? The open API offers all the latest methods to fulfill your tightest integrations.

Not only will jPDF Signer let you display a visual annotation of a signature on a document, it will let you customize the signature’s text, formatting and background image.
