WebMar 16, 2024 · RSA algorithm is the most popular asymmetric key cryptographic algorithm depends on the mathematical fact that it is simply to discover and multiply large prime numbers but complex to factor their product. It needs both private and public key. Example of RSA Algorithm. Let us take an example of this procedure to learn the concepts. WebRSA in Practice. RSA works because knowledge of the public key does not reveal the private key. Note that both the public and private keys contain the important number n = p * q.The security of the system relies on the fact that n is hard to factor-- that is, given a large number (even one which is known to have only two prime factors) there is no easy way …
