I'm not sure whether that statement is correct. 1183626 3 bfulgham 2016-04-13 21:22:40 -0700 It looks like we are not up-to-date with http://www.w3.org/TR/WebCryptoAPI/. 1183718 4 ap 2016-04-14 09:12:27 -0700 That statement is probably obsolete, JWK added many new identifiers since then. 1251492 5 jiewen_tan 2016-11-15 11:11:04 -0800 This bug should be resolved by Bug 164722.
