What are the 5 basic steps for the RSA cipher?

Friday, 15 September 2023 by Silvio Pereira

The RSA cipher is a widely used public-key encryption algorithm that relies on the mathematical properties of prime numbers and modular arithmetic. It was developed in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman, and has since become one of the most important cryptographic algorithms in use today. The RSA cipher is based on

What are the key steps in the process of generating an Elgamal digital signature?

Thursday, 03 August 2023 by EITCA Academy

The Elgamal digital signature scheme is a widely used cryptographic algorithm for providing data integrity, authentication, and non-repudiation in secure communication systems. It is based on the principles of public-key cryptography, where a private key is used for signing messages and a corresponding public key is used for verifying the signatures. In this answer, we
