They factored a *special* number. The chance that someone would pick a Mersenne number as their key is as close to zero as one can get in this universe. As they said in their paper, the effort they used is about the same as would be needed for factoring a 700-bit number, and they think 768 bits is possible for them with a similar hardware setup. The next paper from the group should give more detail about the actual requirements for the final steps in sieving a non-special 1024 bit number. _______________________________________________ dev-tech-crypto mailing list dev-tech-crypto@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-tech-crypto
