How Digital Signature work
Like handwritten signatures, digital signatures are unique to each signer. The providers of digital signing solutions, such as DocuSign, follow a specific protocol called Public Key Infrastructure (PKI). PKI requires the provider to use a mathematical algorithm to generate two long numbers called keys. One key is public, and one key is private.
When someone electronically signs a document, the signature is created using the signer’s private key, which is always securely kept by the signer. The mathematical algorithm acts as a cypher, creating data matching the signed document, called a hash, and encrypting that data. The resulting encrypted data is the digital signature. The signature is also marked with the time that the document was signed. If the document changes after signing, the digital signature is invalidated.
For instance, suppose that Jane signs a timeshare sale agreement with her private key. The buyer receives the document. A copy of Jane's public key is also sent to the document's purchaser. If the signature is not Jane's or the document has changed since it was signed, the public key will be unable to decrypt it using the cypher that produced the keys. The signature is then invalid. To ensure the integrity of the signature, PKI mandates that keys be generated, carried out, and stored securely. As a result, a reliable Certificate Authority (CA) is typically required. Companies that provide digital signatures, like DocuSign, address the PKI criteria for secure digital signatures.
