WebAs pointed by Thomas Pornin, in order to decrypt c, an attacker can replace it with c ′ = ( c ⋅ ( r e mod n)) mod n for some random r; the resulting m ′ is m ⋅ r mod n and will not make sense to the decipherer, but if m ′ gets revealed, the attacker can deduce m as m = ( m ′ ⋅ ( r − 1 mod n) mod n). The solution is easy: never use plain RSA.
