[freenet-dev] Key size maximum?

2003-07-29 Thread Toad
I suggest that we should have a maximum key size of 1MB. Of course this would be configurable, but the network default should be 1MB. Why? * 1MB is cacheable on any node that is not using an unsupported stupidly small store. Files moving through the network that are only cacheable on a few node

I don't want to limit myself to 160 bits. I just don't like limits, regardless of what calculations you can make at how impossible it is to reach them. If we are dealing only with KHKs, then 160 bits is too long anyways. A generous estimate says that language has 1.6 bits of entropy per character

Many thanks to Hal and Oskar for pointing out the mistakes in my key format; but one thing I'd like to defend is the 160-bit key size. As Hal points out, DSA keys are bigger, but they too can be hashed again to fit into 160 bits. The text format of messages we have will allow for bigger keys if
