If you choose any two numbers, the RSA encryption and decryption is still correct. However, not all numbers of a given length are equally hard to factor. The hardest instances of these problems (for currently known techniques) are semiprimes, the product of two prime numbers. For example, factoring 35 (= 5 * 7) is difficult than 36 (= 4 * 9 or 6 * 6).

What does 14k RSA mean?
14k RSA refers to a key size of 14,000 bits in the RSA encryption algorithm. RSA, which stands for Rivest-Shamir-Adleman, is a widely used method for secure data transmission. A key size of 14k is significantly larger than the commonly used sizes (like 2048 or 4096 bits), offering enhanced security but also requiring more computational resources for encryption and decryption processes. However, it's important to note that such large key sizes can lead to diminishing returns in security versus performance.
What is meant by RSA encryption?
RSA encrpytion refers to a type of security thats main advantage is the alleged difficulty of factoring large integers. It is based on taking two prime numbers together and creating a huge number out of them.
How do you write an algorithm to check whether a number is a prime number or not?
Checking if a number is prime is a popular question for programming competitions. It's also necessary when implementing software that generates private keys for RSA public-key encryption. There are several formulas for computing the prime numbers such as Willans' Formulas and Wormell's Formula. These two are used to generate a prime number. The simplest way to check if a given number is prime (primality testing) is to search for a factor. Try possible factors and see if the number can be evenly divided into any of them. In C, that simple check is: bool IsPrime(long int number) { if (number < 2) return false; if (number <= 3) return true; long int ns, temp; for (ns = 3; ns < number; ns++) { temp = number / ns; if (temp*ns number) { printf("The smallest prime factor of %li is %li .\n", number, ns ); printf("The product of %li * %li is %li .\n", ns, temp, number ); return false; //can be divided! } } return true; } This can be sped up a little more by only checking primes (rather than every odd number), perhaps using the sieve of Eratosthenes to find those primes. Because all primes are integers, it's usually best not to use floating-point when working with them. Even with all known speedups, every known method for factorizing a number is still too slow for some applications -- it would take centuries to check the numbers used in RSA public-key encryption -- and so people have developed much faster, much more complicated algorithms for primality testing. These fast algorithms can prove that a number is almost certainly prime; however, when they indicate that a number is composite, they don't reveal any of the factors of that composite number. Such fast algorithms include the Fermat primality test, the cyclotomy test, the Lucas test, the Proth test. the Miller-Rabin primality test, the Solovay-Strassen primality test, and the AKS primality test. The implementation, of those formula, unfortunately cannot be listed in here.
