An earlier post indicated that we might be doing more harm than good by
showing just how long it takes to crack RC5-64. Since 56-bit is
currently the highest exportable system, I have an idea: why don't we
just crack RC5-56 over and over again?
By my calculations, we could exhaust an RC5-56 keyspace every month. We
could plot our progress to estimate when we could crack arbitrary RC5-56
messages in 1 day. Then our message could be that RC5-56 has a useful
lifetime of only x years!
Just a thought, let me know what you think.
