DIGITAL SIGNATURE
A digital signature is a cryptographic technique that verifies the authenticity and integrity of a digital document, message, or data. Its similar to a personal signature on a written document.
A digital signature is an electronic, encrypted stamp of authentication that
Confirms the information originated from the signer
Ensures the content of the information has not been tampered with during transmission
Digital signatures use a variety of security features, including Asymmetric cryptography, Checksums, CRC, CA validation, and TSP validation.
Digital signatures are legally binding in many countries, including the United States and the European Union.
A Digital Signature Certificate (DSC) is the digital equivalent of a physical certificate, such as a drivers license or passport. A DSC can be used to prove ones identity, access information or services on the internet, or sign documents digitally.
