The strength of an RSA encryption relates to the length of the integer — which defines how big the problem is. For example, a 50-bit integer has 9.67 x 10^16 possible values.

Current RSA keys, ranging from 1024 to 2048 bits, would require quantum computing power still far beyond today's... read more ⯈ 💻 Chinese researchers succeed in breaking RSA encryption using ...

The method, outlined in a scientific paper published in late December, could be used to break the RSA algorithm that underpins most online encryption using a quantum machine with only 372 qubits ...
