Digitally signing without end-to-end encryption

How do digital signatures work? Digital signatures, like handwritten signatures, are unique to each signer. Digital signature solution providers, such as DocuSign, follow a specific protocol, called 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. A digital signature is basically a way to ensure that an electronic document (e-mail, spreadsheet, text file, etc.) is authentic. Authentic means that you know who created the document and you know that it has not been altered in any way since that person created it. Verifying the Signature. 1. When you open the document in a digital signature-capable program (e.g., Adobe Reader, Microsoft Office), the program automatically uses the signer's public key (which was included in the digital signature with the document) to decrypt the document hash. 2. The program calculates a new hash for the document.
