Default Secure encrypted data backup?


Are there places that you can access via DSL with a secure encypted link,
that you can back up your data to, where they can also be absolutely
trusted not to snoop or spy on it?

Hi Sarah,

If you can strongly encrypt on your end, then you eliminate the
worry.

Unfortunately, the folks in control of the hardware can snoop on
whatever they want, but if you encrypt the data on your side before it
hits the wire and their equipment, that ceases to be a risk (provided
the encryption is strong and keys secured).


Best Regards,

"absolutely"? Never. If someone's life depends on it, don't do it.
Otherwise, encrypt it yourself and send it away.

Even 128 bit encryption can be cracked by NSA computers if they want.

Considering even an unknown superior technology which does 10000 calculation
steps instead of 10 between two thermodynamically stable states, this would
still require much more energy than boiling all water on earth.

A quantum computer reducing it effectively to 64 bit would be a highly
compressed block of oxygen, shielded much better than a 10 light years thick
wall.

So, well, may I call your statement total bullshit?

Steganos online backup and swissdisk both claim to store your data
encrypted and that not even their employees can access it if you lose
your password.

Sure does Steganos make such a claim, since they want to sell their
software. That doesn't make them any less untrustworthy.
