A digital signature guarantees that an electronic document is authentic. It is an encrypted digital code appended to an electronic document to verify that it was created by a known source and has not been altered.
A digital signature is the technology that proves the authenticity of a document. Digital signatures require a digital certificate from a certificate authority to vet a user's identity. The certificate is bound by cryptography to the signed document, creating a unique digital fingerprint.
Digital signatures also embed a public key infrastructure (PKI) into the signing process. PKIs generate two keys— one public and one private — to identify the signer and the entity requesting the signature. Both the digital certificate and PKI provide stringent identification and security for sensitive legal documents.
Electronic signatures are digital symbols that a signer applies to a contract while digital signatures use encryption methods to authenticate digital documents. While both signatures are legally binding, electronic signatures replace traditional signatures.
