WebA digital signature is based on asymmetric cryptography. It is also known as public-key cryptography. There are a number of public-key algorithms. But among them, two are widely used are RSA (Rivest-Shamir-Adleman) and SHA (Secure Hash Algorithms). Both algorithms are used for secure data transmission. WebSimilarly, a digital signature is a technique that binds a person/entity to the digital data. This binding can be independently verified by receiver as well as any third party. Digital …
