Yes, there will, and we'll send those who suggest we remove it from this location the relevant security analysis and that will be that. > It seems prudent NOT to use SHA-1 precisely for the > same reason we are not using MD5. Not really. We are (well, were before Stefan changed it) using SHA-1 because it's what everyone uses. Which, incidentally, is precisely the argument for using it instead of FNV-1, which, by comparison, practically nobody uses. -Ekr
