How many times do people have to say this: There is no such thing as secure email. Assume everything is being read. You can't bolt security on (SSL, mailbox encryption, PKI). You have to design it in from the start. SMTP/IMAP etc have crudely hacked on TLS implementations which aren't even guaranteed to be operational site to site. PGP is just an encapsulation which is rarely used. It's a mess. This is just a repacka…
I don't think Mailpile is potentially valuable because it immediately solves the encryption problem, but because it solves the MUA problem. All innovation in the secure email space has been blocked for the past 13 years by one primary problem: webmail . It is simply not possible to develop a secure email solution if webmail is the only viable option for accessing mail, so most people who would be interested in innova…
Private keys are kept in the domain of a browser extension, so even if your webmail provider served up malicious javascript (via xss or court order), they would not be able to directly read the contents of your emails since they are being encrypted/decrypted in a separate domain.
Ideally the crypto APIs in browsers would work nicer with hardware tokens etc, but until then, at least people can start moving towards GPG without having to trust large, scary, poorly maintained email clients like thunderbird and evolution, which tend to segfault with a terrifying frequency.
