Digital signature is a type of electronic authentication method that uses encryption techniques to confirm the identity of the sender of a document or file, and to ensure the file's integrity and authenticity. The digital signature is unique to each sender and is virtually impossible to duplicate or forge. It provides assurance that the message or document has not been tampered with and that the sender is who they claim to be. Digital certificates and package and sign are related but different concepts. ACCDE is not relevant to this context.
