If the output is exactly 256 bytes, there are (in theory) 2^(256*8) possible outputs. That means there can be at most 2^(256*8) possible inputs. There are more than 2^(256*8) possible input strings of 256 bytes or less (since there are that many strings just of exactly 256 bytes). So there's no way it can possibly take all input strings of 256 bytes or less. In any event, unless you know exactly what you are doing, you should not be using PK algorithms directly. There are *way* too many gotchas. Use a system that includes the PK algorithm you.
