RE: Must we authenticate login forms (using SSL?)?

["Nathaniel S. H. Brown" <nshb () inimit com>]

I have created a very unique, yet simple method of a form encryption that
provides the same mechanism that the public/private key entails.

Check out my just published release at
http://www.nshb.net/secure-form-post-with-javascript-without-ssl

Look forward to hearing any feedback you guys have :)

Warmest regards,
Nathan.
