"WebAn RSA public key consists of an exponent e and a modulus n. For this project we are only concerned with the modulus. An RSA modulus is the product of two secret prime numbers p and q: n = pq. For security, p and q are large prime numbers, typically at least 1024 bits in binary; then n is a 2048-bit binary number. Here is an example: " - Crack rsa public key
