The RSA algorithm involves four steps: key generation, key distribution, encryption, and decryption. A basic principle behind RSA is the observation that it is practical to find three very large positive integers e, d, and n, such that with modular exponentiation for all integers m (with 0 ≤ m < n): and that knowing e and n, or even m, it can be extremely difficult to find d. The triple bar (≡) here denotes modular congruence (which is to say that when you divide (m ) by n and m by n, they bot…
