What is a digital signature and how does it work?
A digital signature, also referred to as an Advanced Electronic Signature (AES or AESign), or a Qualified Electronic Signature (eIDAS, EU) is a type of electronic signature that is backed by a digital certificate (x.509) that complies with the strictest eSign legal regulations

How digital signatures work
A digital signature is a mathematical technique used to validate the authenticity and integrity of a message or an electronic document.
The signatures are based on public-key cryptography, using a public key algorithm to generate two keys - one public, and one private.
In most countries, a digital signature is the equivalent of a handwritten signature, as it offers more inherent security than a simple electronic signature. A digital signature cryptographically seals the message (or document), making it tamper-evident.
Digital signatures provide evidence of identity, which can be digitally verified using trust indicators that are built into the signatures and embedded into the document.
What is SigniFlow's approach to digital signatures?
SigniFlow’s approach to digital signatures means we are able to offer more flexibility and control over the type of signatures used, compared to that offered by most eSign competitor platforms.
With SigniFlow, you have the option to request signers to sign with an electronic signature, digital signature, or enforce a personal digital certificate, or a combination thereof. This allows you to build workflows that suit the legal requirements of your business, or a specific document.
SigniFlow supports a range of secure signature creation devices, including USB tokens, smart cards, and cloud-based x.509 digital certificates.
SigniFlow is "certificate-agnostic", meaning you can use almost any certificate authority (CA) or timestamp authority (TSA), with support for many CAs and trusted authorities through the European Union Trusted List (EUTL) and globally through the Adobe Approved Trust List (AATL).
Digital signatures come standard with SigniFlow as a core offering. We also offer cryptography as a service (CaaS) for customers that have their own app or workflow software, and merely want digital signature functionality built in, without having to deploy Public Key Infrastructure.
Digital signature features
All signatures are created using digital X.509 standard for public-key certificates.
Timestamping is applied through a trusted Timestamping Authority (TSA).
Embedded record of the state of the certificate at the time of signing.
Document content is protected from start to end using cryptographic algorithms.
Full auditable X.509 trusted AATL embedments for every signer in the workflow.
An automated history of events are logged against a unique document ID.
SECURE AUDIT LOG
Audit logs are written and sealed into the document using steganography.
AATL and EUTL
Supports Adobe® Accredited Trust List and European Union Accredit Trust List.
Multi-factor authentication and AD, LDAP, OAuth, SAML, and other options are available.
Embedded auditable record of the geographical location of signatories.
