Visitors to the Cryptosmith site are not required to register. However, you must register if you wish to post a comment or trackback to a blog entry on the site.
You may use OpenID to register with Cryptosmith. This avoids the problem of sharing a password with this site.
The user registration process will collect an email address. The site will use this email address to reset your Cryptosmith password if you lose or forget it. I also reserve the right to contact you via that email address. Such email contacts will happen rarely if at all.
