What are the prime numbers in Internet encryption?
Can you elaborate on the significance of prime numbers in the realm of Internet encryption? How exactly do they contribute to the security and integrity of our online transactions? Is it their unique, indivisible nature that makes them so crucial in this field? I'm particularly curious about the mathematical underpinnings and how they translate into practical safeguards against cyber threats. Could you also discuss any potential limitations or vulnerabilities associated with relying solely on prime numbers for encryption purposes?
