My bad. Anyway, my question was really only about how to deal with these (already deployed) curves using JOSE. Anders
I wouldn't recommend secp256k1 - its patented, see http://www.freepatentsonline.com/7110538.html http://www.freepatentsonline.com/7995752.html This curve supports an endomorphism, which means it can be computed on somewhat faster, although its cryptographic strength suffers a little as well. There is little to recommend the brainpool curves - they are based on the superstition that random primes are better. If you want new improved curves look at more recent literature, for example http://safecurves.cr.yp.to/ or http://eprint.iacr.org/2014/130 Mike On Fri, Dec 19, 2014 at 6:42 AM, Anders Rundgren <[email protected] <mailto:[email protected]>> wrote: Somewhat related to my "WebCrypto/JOSE Algorithm IDs = Mess" posting I wonder how you are supposed to for example deal with "brainpool" algorithms which are more or less an EU standard? The bitcoin folks apparently use yet another EC algorithm ("secp256k1" in JCE).
