Explanation:
Detailed explanation-1: -Digital signatures are based on public key cryptography, also known as asymmetric cryptography. Using a public key algorithm–such as Rivest-Shamir-Adleman, or RSA–two keys are generated, creating a mathematically linked pair of keys: one private and one public.
Detailed explanation-2: -Through PKI, each digital signature transaction includes a pair of keys: a private key and a public key. As the name implies, the private key is not shared and is used only by the signer to sign documents electronically.
