Hello Sputnik,

The short answer to your question, is yes, 128-bits suffices.

The medium answer is that it’s really about your password. If you have a weak password you’re not using the full strength of the algorithm, and then it does not matter if it’s 128 or 256 or whatever. So, you need a really strong password. The problem here is that it’s actually quite hard to type and remember a password that is equivalent to 128 bits, not to say 256.

If you use our password generator┬áthe strong password is approximately equivalent to 95 bits, and the short about 30 bits, so you can take a long and add a short, and you’ll get full strength.

In my personal opinion the long password is sufficient for all reasonable and most unreasonable attacks. A government might possibly crack such a password with time and some luck (there’s some strengthening added to, so it’s really about 105 – 110 bits), but only at great expense if at all. Personally I doubt it. A real 128-bit equivalent is currently out of the reach for anyone, including governments.
