Digital signature (cryptography)

Digital signatures are a standard element of most cryptographic protocol suites, and are commonly used for software distribution, financial transactions, contract management softwarecontract management software, and in other cases where it is important to detect forgery or tampering.

Digital signatures, just like hand-written signatures, are a means to prove that a communication came from a definite, identified source. Digital signatures utilized cryptography for better security.

A digital signature is a mathematical scheme for demonstrating the authenticity of digital messages or documents. A valid digital signature gives a recipient reason to believe that the message was created by a known sender (authentication), that the sender cannot deny having sent the message (non-repudiation), and that the message was not altered in transit (integrity).
