Secure document workflows with Digital Signatures—certified, encrypted, and secure.
Digital Signatures can be used to verify a document’s origin and to make sure it hasn’t been tampered with after a certain point in time.
A digital signature on a PDF document is a reliable proof of the document’s origin.
An encrypted hash is used to verify that the document hasn’t been tampered with.
PSPDFKit supports both hand-drawn signatures and encrypted, digital certificate-based signatures.
