RSA is the best-known public key encryption algorithm. In this algorithm each participant has a private key that is shared with no one else and a public key which is published so everyone knows it. To send a secure message to this participant, you encrypt the message using the widely k...
How the RSA algorithm is used: An example The following is an example of the RSA encryption algorithm in action: Alice generates her RSA keys by selecting two primes: p=11 and q=13. The modulus is n=p×q=143. The totient is n ϕ(n)=(p−1)x(q−1)=120. She chooses 7 for...
1.n += 2 if n & 1 else 1:这一行使用了条件表达式。如果 n 是奇数(即 n & 1 为真),则 n 增加2,否则增加1。这是因为偶数不可能是素数,所以我们跳过偶数,直接考虑下一个奇数。 2.while not isPrime(n)::这是一个循环,它一直进行直到 n 是素数为止。
