PHP encrypt of html text (password) and then Javascript decryption

[oldrich.svec]

Is there any way how to encrypt some html text in php and afterwards
decrypt it with javascript and send it with form?
Example:
<input type="hidden" value="password"/>
I don't want to have seen value "password" in html source code but I
need to send the value by form...

Well you could ... but what would be the point? You'd be effectively putting
the password in a locked box, then giving it AND THE KEY to the browser
(and anyone viewing source could see the key too).
