WebThe Rivest-Shamir-Adleman (RSA) Algorithm is a public-key crypto algorithm. It is based on the principle that prime factorization of a large composite number is tough. Only the private key of the receiver can decrypt the cipher message. RSA is a key pair generator. Choose two different large random prime numbers p and q Calculate n = p q WebSimilarly, you can install rsa on macOS in four steps: Open your macOS terminal.

WebWell, you could do the same as regular textbook RSA, compute m = c d mod n for the decryption exponent d. However, that's silly; the entire point of multiprime RSA is that it's faster than regular RSA, and the above isn't. Instead, what we do is first compute the three values: m p = ( c mod p) d p mod p. m q = ( c mod q) d q mod q.
