WebJul 30, 2024 · RSA key generation works by computing: n = pq. φ = (p-1) (q-1) d = (1/e) mod φ. So given p, q, you can compute n and φ trivially via multiplication. From e and φ you can compute d, which is the secret key exponent. From there, your public key is [n, e] and your private key is [d, p, q]. Once you know those, you have the keys and can decrypt ...
