The Doghouse: KRYPTO 2.0
のネタをBruce Shneierのblogから引っ張ってきました。
Why are 256 bits the technically highest coding depth at all on computers possible are ?A computer knows only 256 different indications.
1 indication = 1 byte has 8 bits in binary the number system exactly.
1 bit knows only the switching status: on or out or 0 or 1 by the combination of these 8 bits results 256 bits.
The computation in addition: 2 switching status highly 8 bits = 256 bits these 256 bits
is addressed in decimally the number system from 0 to 255 = 256 bits.
Computers work however in in hexadecimals the number system.
There these 256 bits designated above are addressed from 00 to FF = 256 bits.
A byte cannot be thus under bits 0 or over bits 255.
Therefore 256 bits are the technically highest coding depth at all on computers
possible are.

#念のため, Bruce Shneier氏が書いた文章ではなく、 http://kryptochef.net/index2e.htm に掲載されていた文章です。
Krypto uses repeated 256 bits (full bits) a coding purely been based on information of the keys file, which are the technically highest coding depth at all on computers possible are.
頭痛がしてきました。
SchnierさんもMy head hurts just trying to read that.
とか書いてます。:-)
