Is it hard to crack a 20 character password?

The 20-bit password is half as hard to crack as a password with 21 bits. A password with 20 bits of entropy is drawn uniformly and randomly from 2²⁰ possible distinct passwords. That’s just over 1 million, and approximately the strength you would get from a 4-character generated password.

How fast is Google’s quantum computer?

In 200 seconds, the machine performed a mathematically designed calculation so complex that it would take the world’s most powerful supercomputer, IBM’s Summit, 10,000 years to do it. This makes Google’s quantum computer about 158 million times faster than the world’s fastest supercomputer.

How long would it take to crack RSA 4096?

We show an attack that can extract whole 4096-bit RSA keys within about one hour using just the acoustic emanations from the target machine. The choice of the size of the 4096 bit number is more as a Proof of Concept that it is possible to do it with big number.
