Subject: [stella] Atari 7800 signing program From: "Frank Palazzolo" <palazzol@xxxxxxxx> Date: Wed, 15 Aug 2001 22:49:44 -0400 |
I updated my signing program, still available here: http://www.dsplib.com/a7800/a78sign.zip I've tested it on many files, but I'd still be a bit careful with it until a few people get to exercize it. There is a decent commentary in the source about the math. FWIW, there are no issues with the algorithm or the math, except that I'm still curious if the hash algorithm is a "standard" or not. I probably wont update this program now unless there are bugs, or I get inspired to make a it completely self-contained program (i.e. no 3rd-part library needed.) Here is the new usage statement: Usage: a78sign [option] file -c = check mode only -f = force overwrite of invalid signature Default is overwrite only if signature is all zeros Notes: You cannot overwrite a valid signature. This program supports .a78 files, and raw binary files up to 48K I hope this inspires some budding 7800 programmers...! Thanks to everyone who helped make this possible, -Frank - Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
