Webcrypto Message intercepted. Break it. babyrsa.zip We are given the encryption (with no padding) of a short message with a 4096-bit RSA key with e = 5 . Recall that RSA encrypts with c = me mod n . Because m is short and e is small, me < n . Because it never wraps around, we can take the fifth root as in normal arithmetic.
