Hi, everyone!
I want to know what's the bitlength relationship of RSA's key pair.
For example, n is 1024bit, e (public key) is xbit, then what is the
bitlength of d (private key)?
Thanks in advance!

Thank you all! In fact, I want to compare the timing of RSA with that
of ElGamal. If n and p are both 1024bit, I was told that the
exponent's bitlength determines the timing.
As we know, for ElGamal, the exponent's bitlength is 160bit, while
for RSA I have no idea about know. I just know that e usually equals
to 65537, and d must larger than n^{0.3}.
Thanks!
