Note that Trevor Perrin started down this path re ECDH: http://www.w3.org/2012/webcrypto/WebCryptoCurve25519/Curve25519-WebCrypto.html So we could continue and co-ordinate with CFRG re representational issues. However, we need a clear signal from CFRG that indeed, Curve 25519 would be suitable for the 128 bit security level. I believe that consensus has been found inside CFRG, not sure when the plan was to send it to the outside the world. cheers, harry > > Sincerely, > Watson Ladd >> >> cheers, >> harry >> >> [1] >> > http://www.w3.org/2012/webcrypto/DispositionOfComments/WebCryptoDispositionOfComments.html >> >> _______________________________________________ >> Cfrg mailing list >> Cfrg@irtf.org >> http://www.irtf.org/mailman/listinfo/cfrg >
