What’s the difference between certificate-based digital signatures and e-signatures?
To put it simply, electronic signature (or e-signature) is a broad term referring to any electronic process that indicates acceptance of an agreement or a record. A certificate-based digital signature (often just called a digital signature) is a specific type of e-signature.
Typical e-signature solutions use common electronic authentication methods to verify signer identity, such as an email address, a corporate ID, or a phone PIN. If increased security is needed, multifactor authentication may be used. Digital signatures use certificate-based digital IDs from TSPs and demonstrate proof of signing by binding each signature to the document with cryptography.
