[REBOL] subtracting binaries
From: maarten:vrijheid at: 1-Apr-2004 16:55
Hi, As anybody (efficiently) tackled suntracting two binary! values. I want to compute the difference between two 160 bit SHA1 keys, with the outcome a new binary. And I also need addition which sould be circular in 160bit space. E.g 2^160 + 1 = 1 Before re-inventing yet another wheel I'd thought I'd ask to see if anybody has already written this. --Maarten
