WebMay 7, 2014 · A side remark: RSA decryption is slower than encryption, as typically used. The expensive operation of RSA decryption is an exponentiation: C = P^d (mod n). The corresponding encryption operation is very similar — P = C^e (mod n). The speed difference comes from the fact that we can, and do, choose the public exponent e to make the ...
