It is inadvisable that anyone use Lokmail. The implications of a
"trust-us" encrypted mail service are obvious, and the people behind
Lokmail are of dubious integrity.

If you're looking for secure web-based PGP, look at www.hushmail.com.

What's wrong with PuTTY on a floppy, USB stick, or
http://leitl.org/putty.exe ? Works every time.

I normally run a java-ssh applet using one time passwords to a mostly
throwaway account, loaded off an https web page, when I need remote
access from untrusted machines.  It works pretty well.

If I were using PGP like that, I'd probably disavow read perms on the
key and use an suid-another-user pgp script, to try to protect the PGP
key itself from copying...sort of analogous to a smartcard.

Using untrusted hardware for secure computation is living in sin, but
it's not too hard to minimize the risk.

ipaq running linux with 1xRTT and 802.11b is smaller than a .380, and
vastly more useful in modern warfare, though.

And (dumbass) you would trust the keyboard and display of an internet cafe
is safe to type in your passphrase?  Never heard of keystroke capturing?

You're better off trying to find a WiFi access point - i.e. Starbucks or
whatever cafe and using that instead with your own trusted hardware.

That said, you can use hushmail...

Yup.
1. download putty
2. run putty
3. run batchfile that changes password to next oneshot
4. do whatever is needed
5. exit putty 

:)
