Don’t Worry, We’ll Double-Check

Tamper-Safe

Digital Signatures can be used to verify a document’s origin and to make sure it hasn’t been tampered with after signing.

Guides

Extensible

As a developer, you can add additional metadata — like a timestamp or an IP address — to a digital signature for even better security.

Benefits

Certificate-Based, Encrypted, and Secure

Proof of Authenticity

A digital signature on a PDF document is reliable proof of the document’s origin.

Protection against Modification

An encrypted hash is used to verify that the document hasn’t been tampered with.

Biometric Signatures

Our digital signatures are created with additional biometric properties for added safety.
