That is not comparable. The threat of quantum computers, if they can really grow exponential speeds, makes current asymetric ciphers completely useless. Sure, we could go with 16384 bit keys and sit an wait for half an hour while our nodes handshake, just to give us 26 years instead of 22. The fact is we HAVE to hope that this will get fixed later (or that the threat is not as bad as it's cracked out to be - which is the worse alternative since there are many good uses for quantum computing), or we simply can't use asymetric ciphers at all. > > -- > Travis Bemann > Sendmail is still screwed up on my box. > My email address is really bemann at execpc.com. -- \oskar _______________________________________________ Freenet-dev mailing list Freenet-dev at lists.sourceforge.net http://lists.sourceforge.net/mailman/listinfo/freenet-dev
