Hvorfor er det lige 3DES skulle være usikker?
Er det algoritmen der er 'huller' i?
Nøglen er jo 3x56 bit = 168 bit, hvilket vel stadig opfattes som ret sikkert.


3DES anses stadig som sikker og benyttes i mange applikationer. Men
resonnementet med at gange bitstørrelsen sammen og benytte den til at
vurdere pga. er ikke nogen god taktik. Jeg kan sagtens lave en hullet
10-millioner bit krypteringsalgoritme.


Det er jo netop derfor jeg spørger om algoritmen er 'hullet', for hvis den ikke er det, siger antallet af bit noget om hvor meget 'brute force' der skal anvendes for at knække kodningen.
