Kanal how does signature analysis work?

[5Alive]

That could be the answer, RC5 uses 2 constants :
1.) the base of natural logarithms
2.) the golden ratio.

I expect RC6 will be the same as this too is a parameterized algorithm where block size, key size, and the number of rounds are variable; with a 2040 bit upper limit on the key size.

Are the any crypto experts on this forum that know how to exploit poorly implemented rc5 code to obtain private keys?

Or has anyone seen keygens for apps that use rc5 in there protection scheme? I need all the help I can get.

All my searches point to the distributed.net site which is of no real help to me.

Thanks for the replies so far.
