Is password encryption asymmetrically using JavaScript viable?

Question

I would like to use JavaScript to encrypt the user password and username at login (using Ajax). I know that there are several asymmetric encryption libraries for JavaScript. Is this a viable password security strategy?

I understand that SSL exists, but that is not a question.

Answer 1

No. It does not matter if the attacker receives a password or an encrypted password, both are sent to the server “unencrypted”, so the encrypted password can be used to log into the system.
