Fair enough for Iranian/Chinese users perhaps but I thought Hushmail was no longer secure - ever since they handed over user data in response to a subpoena.
There's nothing wrong with handing over data in response to a subpoena. They're legally required to do so. The problem is with providers who hand over data without a subpoena.
It is their ability to decrypt that scares me. Most of the users were under the impression that Hushmail did not save their keys.
They didn't, but the they were forced to setup something on their servers that allowed them to capture the keys (or something like that) in one particular instance, IIRC.
It's not clear it's legal for Hushmail to do that. or so I'm told.
