Do the key check values of two-key 3DES keys have a uniform distribution? If not I'm curious as to what the distribution is.
I ask because I want to know how safe it is to use a key's KCV as an identifier for that key. If the distribution is uniform, then I believe that I can calculate the chances of a KCV collision via the birthday problem and use that to decide whether KCVs are a safe ID for my use case.
