Mutual Authentication scheme

[Danny <danny248 () gmail com>]

I am developing a web solution for the company that I work for and would
like to have as much security as possible. SSL only authenticates the
server to the client and I would like a way to authenticate both parties
to each other. Any ideas/suggestions?

BTW: I will be using Apache 1.3.29 w/ mod_ssl, and OpenSSL v0.9.7
running on OpenBSD 4.0

Thanks,
Danny
