Summary0003310: DHT should have a randomization option
DescriptionDHT should have a configuration option to indicate the minimum/maximum amounts of randomization used for keys, and a fixed hardcoded limit (64 bits).
Additional InformationThe hardcoded limit is in place so requests with different randomization "sizes" are compatible with each other.
- A peer that decides to do a PUT with 16 bits randomized can use a value of up to 0x000000000000FFFF to hash with the original ID.
- A peer that decided to do a GET with 8 bits randomized withh use a value of up to 0x00000000000000FF to hash with to original ID.
- If the PUT was done with a value of 0x0000000000000000 to 0x00000000000000FF, the GET has a chance to be found. If the PUT was done with a value of 0x0000000000000100 to 0x000000000000FFFF the GET won't succeed.


If the PUT was done with a hash value from 0x0000 to 0xFFFF, a GET for a hash value from 0x00 to 0xFF, the GET would never succeed. This is because hashing 0x00FF and 0xFF result in different values.
