Techopedia Explains Digital Signature
A digital signature is applied and verified, as follows:
- The document or message sender (signer) or public/private key supplier shares the public key with the end user(s).
- The sender, using his private key, appends the encrypted signature to the message or document.
- The end user decrypts the document and verifies the signature, which lets the end user know that the document is from the original sender.
