What Is Digital Signature?
A cryptographic "signature" that confirms the origin and integrity of a message or file.
A digital signature uses the sender's private key to "sign" a message or file. Anyone with the corresponding public key can verify that the content genuinely came from the claimed sender and was not altered in transit.
