Split key ring.Definition: "a key split at one end like a split pin, for the same purpose". I have never seen such a key, which isn't a proof of anything, of course. There's a "split ring" or "split key ring" which may be used as a fastener in a similar way as a split pin. In encryption technology split key refers to an arrangement in which the decrypting key is split into several parts, all of which are required for successful decryption. --Hekaheka (talk) 05:21, 10 October 2016 (UTC)[reply]
I have cited the existing meaning, and supplied entries for the missing meanings. "split key ring" is not "split key - ring" it is "split - key ring", so I did not include that meaning. Kiwima (talk) 22:22, 22 April 2017 (UTC)[reply]
