A digital signature is a mathematical technique used to validate the authenticity and integrity of a message, software or digital document. It is the digital equivalent of a handwritten signature or stamped seal.

WebIn cryptography, it is common to talk about keys (usually a short piece of data) to refer to special inputs of a cryptographic algorithm. The most common keys are those used for data encryption; however, other types of keys exist for different purposes. WebGenerally, symmetric cryptography is used when a large amount of data needs to be encrypted or when the encryption must be done within a given time period; asymmetric cryptography is used for short messages, for example, to protect key distribution for a symmetric cryptographic system.
