Is Gutmann critical of DJB in "On the Impending Crypto Monoculture"
http://www.metzdowd.com/pipermail/cryptography/2016-March/028824.html On the Impending Crypto Monoculture Peter Gutmann Is Gutmann critical of DJB (the creator of the divine qmail)? (there is some disagreement about this with alleged linux admins). Maybe I will troll DJB no matter which way it is ;)
Short version: He isn't. -Travis On Fri, Mar 25, 2016 at 10:46 AM, Georgi Guninski <guninski@guninski.com> wrote:

Just for a start, why the elliptic curve is of so small order, only 256 bits? I am pretty sure in the early days of PGP, some PGP advocate claimed something along the lines "we can't factor 128 bit modulus till the end of time". Not to mention quantum computer will fuck the curve fast.

Yes, it is known that quantum computers will break at least most of today's public key crypto (factoring, discrete logarithms) very efficiently. Several years ago IBM tested this in practice with the toy experiment of factoring 15. Some cryptographers are preparing for the day when quantum computers will come -- the buzzword is "post-quantum cryptography". I am a newbie at this and suspect the full potential of quantum computers is not currently known (AFAICT it is open if they will break SAT).
