end-to-end encryption

[Matej Kovacic <matej.kovacic@xxxxxxxxx>]

Hi,

this is not directly connected to Tor, but I think it is important issue 
because we need good support programs for Tor. By support programs I 
mean Firefox, etc. which USE Tor.

The problem is people are extensively using webmail. They can use 
"mobile" Tor (TorPark), but the problem is the content of the webmail is 
not encrypted. So they can get anonymity, but not end-to-end encryption 
(so anonymity is also downgraded).

I was reading this blog: http://www.links.org/?p=130 and comments, and 
got an idea how to enable better security for users using web mail.

My idea is to build GPG into Firefox or at least integrate it more 
deeply. GPG keyring (user's private and public key) should be an object 
similar to certificate.
User will be able to create/import keyring into Firefox, export it or 
delete it. Keyring could be secured with password (with FireFox security 
device), and additionaly with passphrase. Public keys could be easily 
retrieved from public key servers wia Firefox.

How decryption will work?

If FireFox will detect PGP/GPG code (in a form), it will enable decryption.
This need more thinking in detaila, but in general when decrypted, it 
will be "grabbed", decrypted and shown in plaintext. Similar to Enigmail 
extension for Thunderbird.

So user could be able to use strong end-to-end encryption + 
anonymisationn from his/her USB drive.

My observation is, that more and more services are moving into the 
iternet - and mostly into web. So web browser is a central technology 
for browsing, reading email, writing teksts (Writely), publishing 
things, configuring software, watching movies... even runnig OS (see 
YuOS for example) And web browser is becoming independent from other 
systems. In a future local operating system could be only web browser 
with connection to the internet. That is why we need end-to-end 
encryption built into it.

If you find this idea reasonable and interesting, please promote this
