RSA Algorithm, the Keys, and Digital Certificates
Keys are the secrets that allow cryptography to provide confidentiality. Let’s take a closer look at the keys involved with RSA and how they are used.
Who Has Keys and a Digital Certificate?
With RSA digital signatures, with both parties intending on authenticating the other side, each party has a public-private key pair. Going back to the analogy in the previous sections, let’s use two computers named Bob and Lois. They both generated their own public-private key pair, and they both enrolled with a certificate authority (CA). That CA took each of their public keys and their names and IP addresses and created individual digital certificates, and the CA issued these certificates back to Bob and ...
