TweetNaCl: how cr.yp.to’s developers got carried away by the carry bit
- tptacek 12y agocr.yp.to is Daniel Bernstein. Was TweetNaCl written by Bernstein? I thought not. 5 minutes later: Yeah, I should have read this more carefully before jumping in to comment. Sorry. Previous comment preserved as a monument to my dumbness. 5 seconds later: Dammit, Edwin caught me, too. :)
- edwintorok 12y agoThe paper on TweetNaCl lists him as an author, and its a subdomain of cr.yp.to: http://tweetnacl.cr.yp.to/papers.html http://tweetnacl.cr.yp.to/papers.html http://cr.yp.to/papers.html#tweetnacl http://cr.yp.to/papers.html#tweetnacl The bugreport was actually acknowledged by Peter Schwabe. Did djb actually write every line of TweetNaCl? Probably not.
- tptacek 12y agoI actually didn't know he wrote any line of it; I feel like I remember him writing about the person who actually wrote it. But I think I'm wrong about that too. It's a neat post you wrote.
- sebm 12y agoFunny how small is the world, I reported them the same bug on February 13th, you might have been first though :)
- edwintorok 12y agoFWIW I reported mine on 2014-04-22. Was yours about the sizeof(u32) issue, or the carry bit?
- sebm 12y agoIt was only the carry bit [1] and the saved space mention from the ChangeLog. [1] http://seb.dbzteam.org/blog/2014/04/28/tweetnacl_arithmetic_bug.html http://seb.dbzteam.org/blog/2014/04/28/tweetnacl_arithmetic_...
- edwintorok 12y agoLooks like TweetNaCl could use a bugtracker or a mailing list :)
