The digital signature is the equivalent of the handwritten signature and is intended to solve security problems in the digital communication. The signature is unique to each signer and is widely used to confirm that the document content originated from the signer and has not been modified in any way.
A digital signature should have all the aforementioned features of a conventional signature plus a few more as digital signatures are being used in practical, but sensitive, applications such as secure e-mail and credit card transactions over the Internet. Since a digital signature is just a sequence of zeroes and ones, it is desirable for it to have the following properties: the signature

Digital signatures, digital certificates, and advanced electronic signatures are all types of electronic signatures that use cryptography to authenticate the identity of the person signing and to secure their electronic signature. They are all very reliable, but they each have different legal consequences in terms of South African law. Even if you know that you want a very reliable electronic
A digital signature or digital signature scheme is a type of asymmetric cryptography used to simulate the security properties of a handwritten signature on paper.
Digital signatures are used to detect unauthorized modifications to data and to authenticate the identity of the signatory. In addition, the recipient of signed data can use a digital signature as evidence in demonstrating to a third party that the signature was, in fact, generated by the claimed signatory. This is known as non-repudiation, since the signatory cannot easily repudiate the

1 A digital signature is the term used for marking or signing an electronic document, by a process meant to be equivalent to paper signatures, but which makes use of a technology known as public-key cryptography.
A digital signature is an authentication mechanism that enables the creator of the message to attach a code that act as a signature. It is formed by taking the hash of message and encrypting the message with creator’s private key.
