I did a little survey one month ago for my bsc. thesis.

I found out, that round about 1.19% of all https-server-certs use an
exponent <= 17. I did choose round about 32,000 random webservers for
this survey.

What is intresting is what happens when it comes to imap-ssl. Here, only
0.1% of all servers use a server-cert with exponent <= 17. Imap-ssl
users seem to be the better ssl-users, tls 1.0 is more widespread there,
small rsa-modulus-sizes are more seldom, and ssl 2.0 is not so common
there too.

I will publish some more details later.
