For example, it took researchers two years recently to factor a 232-digit number, even with hundreds of parallel computers. That’s why the RSA algorithm is so effective.

The inventors of the RSA algorithm published a list of RSA keys and challenged people to find the original primes, as a way of tracking how secure the encryption is against modern computers.

A recent research paper makes the claim that the RSA cryptographic algorithm can be broken with a quantum algorithm. Skeptics warn: don’t believe everything you read.

Researchers at the University of Michigan have announced that they have found a major weakness in the popular RSA encryption algorithm.

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 ...
