Hi,
the two most common exponents that one finds in X.509 RSA certs are
65537 and 17 -- in my data, they account for near 100%. Have these been
chosen as the result of some standardisation and was there some
cryptographic reasoning behind it, or is it simply that any exponent
will do? Any performance issues?
