What is a digital signature?
A digital signature is a type of electronic signature that uses a specific technical
implementation. It is a method of signing a document online. It is based on Public Key
Infrastructure (PKI) standards - using two keys - a private key and a public key. Digital
signatures satisfy the need for faster and more secure authentication that cannot be easily
forged or compromised.
How does digital signing with Signosoft work?
When a PDF document is signed with a Signosoft digital signature, a unique digital
fingerprint (called hash) is created with a mathematical algorithm. It is specific to the
particular document. The hash is then encrypted into the document, creating a digital
signature. Digital signatures use a mathematical scheme to ensure authenticity, non-
repudiation and integrity of data.
What is the difference between an electronic signature and a digital signature?
An electronic signature is not the same as a digital signature although many use the terms
interchangeably. Electronic signatures, or e-signatures, refer to a wide range of methods for
approving and signing a document. A digital signature is a type of electronic signature that
offers more security and uses a particular technology. Digital signatures from Signosoft
follow a protocol known as Public Key Infrastructure - PKI.
Are digital signatures better than handwritten physical signatures and how?
Digital signatures are cost effective, faster and more secure than physical handwritten
Digital signatures and delivery over internet eliminate paper processing, excessive costs of
printing, filing and shipping; they significantly reduce paper consumption and put a stop to
delays caused by mailing and lost paperwork. Backdating, alternating data or forgery are
next to impossible thanks to encryption. Each digital signature is unique, documented,
encrypted and tamper-evident.
Are digital signatures legally binding?
Yes, digital signatures are fully legally binding and enforceable in almost every developed
country in the world.
From the legal perspective, a digital signature is the equivalent of a handwritten signature on
paper (also called wet signature/ink). Digitally signed documents carry the same weight and
legal effect as traditional paper documents. Within the European Union, the eIDAS
Regulation (2014) provides a predictable regulatory environment to enable secure and
seamless electronic interactions between businesses, citizens and public authorities. In the
United States, there are two Acts that established the legality of digital signatures - the
ESIGN (2000) and the UETA (1999). Read more about Signosoft legal compliance.

the industry's most stringents security standards, and uses strong data encryption. We
