This is an unofficial list of well-known unsolved codes and ciphers. A couple of the better-known unsolved ancient historical scripts are also thrown in, since they tend to come up during any discussion of unsolved codes. There has also been an attempt to sort this list by "fame", as defined by a loose formula involving the number of times that a particular cipher has been written about, and/or how many hits it pulls up on a moderately-sorted web search.
