Anon is correct we they say the file name for the earlier flag is a sha256 hash however. America does not hash in sha256 to the same file name as the earlier flag. From what I can find out so far sha256 is a one way hash. So when you "decrypt" these hashes on the random websites that do that all they are doing is checking it against their database of collected hashes and checking if they have a match. So one possible method would be to build our own database of likely Q related words converted to sha256 and this would give us the name of the earlier flag picture. These file names could be passwords for pixelknot. Also I did note that file names from original Q posts are different than the file names from q.map.pub but that's to be expected no comms outside these boards right.
