Certified, encrypted, and secure document signing workflows.
A digital signature on a PDF document is reliable proof of the document’s origin.
An encrypted hash is used to verify that a document hasn’t been tampered with.
Our digital signatures are created with additional biometric properties for added safety.
As a developer, you can add additional metadata — like a timestamp or an IP address — to a digital signature for even better security.
PSPDFKit supports both hand-drawn signatures and encrypted, digital certificate-based signatures.
