Hi, according to the hint for 10A (which says “we will publish the type of cipher it is at 9am on Friday 15th December”) I thought we’d get the name of what cypher it is today? Or is the cypher’s name hidden in the hint we have already?
[That was the plan, but there was a late change of strategy, so the name of the cipher will not be released immediately. We have a series of hints building up here day by day instead. Hope they keep things interesting for longer. Happy Christmas, Harry]
