How can I testing, it works with 256 function upgade?

Try use with 256 bits full keys?

What mean of 256?
Can using wide of keyspace 256bits
or Can using with full 256 keys?

What feature of kangaroo256 upgrade?


I don't know mush about deep technical and deep programing (just user)
Can possible to develop to 512 bits or 1024 bits? Just ask to known
I think over like bitcoin use at 256 bits or sha256, if creator bitcoin think first time 64bit is high enough now is crack already.
512 bits or 1024 bits is thank like buy power supply for PC buy 1100 Watt PSU and using  600W for performance and long time using with no high heat. something like that
may be possible create 512 bits or 1024 bits for high performance and may be no need to update much in future
may be puzzle up to 120 bit and 160 bits with using 256 bit support may be difficult to scan

and or think reversal 64 bit is short right 256 bit is long right  over 4 time (256/64=4) (and 256/128=2)
It scan possible code for double calculate same time like calculate 64bit 4 calculate parallel in 1 one time
or may be flip method combine 64+64+64+64= 256 bit calculate and split
may be GPU system calculate something like that already no need to think about it
sorry just think about number may be can not possible on technic, I don't know computer knowledge mush
