But there is sometimes need to send credentials while they have not yet established the encrypted channel. The idea is to quickly encrypt text message and publish it to Internet followed by exchange of a symmetric key and the URL by some other communication channel so that recipient may decrypt the message comfortably. After some time, the website page with the encrypted message shall self-destruct. Decryption shall be provided by Emacs Lisp CGI. Thus it will work completely without JavaScript. That is something I wish to make soon as new package. I think Emacs Lisp has everything necessary for this idea to be implemented.
