Digital Signature Benefit 4

How do digital signatures work?

Digital signature use Public Key Infrastructure and mathematical algorithm that generate two long numbers, called keys–one key is public, and one key is private. When you digitally sign a document, the signature is created using your private key, which always securely kept by the signer.

The mathematical algorithm acts like a cipher that creates data matching the signed document, called a hash, and then encrypting that data. The resulting encrypted data is the digital signature–which also marked with time the document was signed. If there are any changes to the document after the signing, then the digital signature is invalidated.
