Message (number < n)

RSA rests on a one-way street: multiplying two big primes is easy, but factoring the product back apart is practically impossible. The public key (n, e) encrypts by raising the message to the power e mod n; only the private key d — computable only from the secret primes — can undo it. Real keys use 600-digit primes; these tiny ones just show the machinery.

Governing equation

n = pq = 17 \cdot 23 = 391, c = m^{e} mod n = 189, m = c^{d} mod n = 42

Reading this result: The public key (n=391, e=3) turns 42 into ciphertext 189; only the private key d=235, derived from the secret primes, brings it back to 42. With primes this small, n could be factored instantly — real RSA uses 600-digit primes.

About this simulation

The full RSA Encryption tool models a Merkle tree with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
