Just to clear up here: This is about breaking RSA, not 'generation keys'. And if I have understood correctly, quantum computing make factoring a trivial excersise due to 'infinite parallelism'. 4096 bits is unlikely to help; _any_ key length is unlikely to help. Check out the RSA FAQ at http://www.rsa.com/ for some more details and references. Eivind.
