Digital signature and Electronic signature

Digital Signatures provide a viable solution for creating legally enforceable electronic records, closing the gap in going fully paperless by completely eliminating the need to print documents for signing. Digital signatures enable
the replacement of slow and expensive paper-based approval processes with fast, low-cost, and fully digital ones. The purpose of a digital signature is the same as that of a handwritten signature. Instead of using pen and paper, a digital signature uses digital keys (public-key cryptography). Like the pen and paper method, a digital signature attaches the identity of the signer to the document and records a binding commitment to the document. However, unlike a handwritten signature, it is considered impossible to forge a digital signature the way a written signature might be. In addition, the digital signature assures that any changes made to the data that has been signed cannot go undetected


Digital signatures are easily transportable, cannot be imitated by someone else and can be automatically time-stamped. A digital signature can be used with any kind of message, whether it is encrypted or plaintext. Thus Digital Signatures provide the following three features:-
