Digital signatures, like handwritten signatures, are unique to each signer. Digital signature solution providers, such as DocuSign, follow a specific protocol called Public Key Infrastructure, or 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.EVERYONE has (or should have) access to the signer's public key. So, to validate a digital signature, the recipient. Calculates a hash of the same data (file, message, etc.), Decrypts the digital signature using the sender's PUBLIC key, and. Compares the 2 hash values. If they match, the signature is considered valid.This type of encryption uses a public/private key pair to encrypt and decrypt data.
