WebJan 6, 2024 · To decrypt this cryptosystem we need \[c^d = (m^e)^d \equiv m \mod n.\] We see that we can do this when $ed \equiv 1 \mod \phi(n)$. To solve the solution we simply need to compute \[d = e^{-1} \mod \phi(n),\] and this is easy to compute given that: $\gcd(e, \phi(n)) = 1$ We know the value of $\phi(n)$ WebCryptoHack chat is based on Discord, which has worked well for us so far.
