i know you have the intellectual curiousity of a sausage, but some of us are simply interested. we don't all need to be motivated by logic.
how would you derive it? tagging pairs of hex digits and sorting doesn't cut it. would rivest have used a hack that's a biased shuffle? i doubt it.
and downvotes. happy xmas!
- tptacek 13y agoYou're right. I was snippy, and in a particularly dumb way. Sorry about that.
- nicholassmith 13y agoBut happy to admit it in a reasonable way. A responsible disclosure of errors if you will.
- andrewcooke 13y agoeh, no need to apologise. i think we're used to you here and there's a level of tolerance given the contributions you make. also, did you see http://www.jakoblell.com/blog/2013/12/22/practical-malleability-attack-against-cbc-encrypted-luks-partitions/ http://www.jakoblell.com/blog/2013/12/22/practical-malleabil... which i think could be added to an early crypto challenge? (but maybe you already cover the idea).
