A digital signature is an authentication mechanism that enables the creator of the message to attach a code that acts as a signature. This signature is formed by taking the hash of the message and encrypting it with the creator's private key, thus tying the document uniquely to the key the sender knows. It ensures the integrity and authenticity of a digital document or message.
