Encrypted field in form (HTTPS question)

[bit-n...@hotmail.com]

I'm trying to set up a simple blogging system, where I have a form which will have a textbox which will allow me to post stuff. Now I want a password field on the form, so that random people cannot post. I would like this password to be ENCRYPTED during transit. So - there'll be TWO textboxes, one for the password, and one for the post itself - what would the coding for the form look like? It's only the password that has to be encrypted, not the post. I realise this is more of an HTML question, but really, it concerns the whole thing, front end as well as back. I have no idea what HTTPS coding on the backend looks like. How would I extract the unencrypted password on the server side?


Thanks for your help.

A form post in pure HTML can not encrypt some data.

You could just submit the form via HTTPS, so the whole form is
encrypted. HTTPS does the encryption in the communication layer, and you
get the unencrypted results (so it is mostly transparent to your script)

A second option, that probably isn't really worth doing, is adding
javascript to the form, and have that run on submit and have the
javascript encrypt the data. You would need to create a new
public/private key for each instance of the form sent out to do the
encryption, and send the public key with the form. On reception, the
page would need to look up the public key to find the matching private
key, and use that to decode the password.
