The RSA cipher, which is widely used in public-key cryptography, utilizes a pair of keys: a public key and a private key. These keys are used in modular algebra computations to encrypt and decrypt messages. The public key consists of one part, while the private key consists of two parts. To understand the role of

To verify a digital signature using the Elgamal digital signature scheme, several steps need to be followed. The Elgamal digital signature scheme is based on the Elgamal encryption scheme and provides a way to verify the authenticity and integrity of digital messages. In this answer, we will explore the steps involved in verifying a digital
