How to make your password UNCRACKABLE applying E=mc^2? Do you know that there is a little-known (outside the computer science community of course), theorem which draws upon famous physics like E=mc² and Heisenberg’s Uncertainty Principle to determine how many minimum number of cryptographic keys to be applied to your password, so that it can NEVER be cracked by brute-force search?

Bremermann’s Limit, named after Hans-Joachim Bremermann, is the maximum computational speed of a self-contained system in the material universe. It is derived from Einstein’s mass-energy equivalency and the Heisenberg uncertainty principle. For example, a computer with the mass of the entire Earth operating at the Bremermann’s limit could perform approximately 10^75 mathematical computations per second. If we assume that a cryptographic key can be tested with only one operation, then a typical 128 bit key could be cracked in under 10^(−36) seconds. However, a 256 bit key (which is already in use in some systems) would take about two minutes to crack. Using a 512 bit key would increase the cracking time to approaching 10^72 years.”
