sha1, sha256 or md5 for 8 bit atari?

Recommended Posts

Hi all

 

anybody know of or has written a utility that can calculate the hash of files on the atari?

 

regards

If you’re planning to do serious crypto work with an A8, better be patient. (Or alternately, do it in Altirra in turbo mode). :)

Speed-optimized MD5 hashing for MOS6502.

 

Just as the title says. I tried to strike a balance between code size and performance, which resulted in around 2KB of code and around 1750 bytes/s when hashing on a Commodore 64.

 

MD5.COM to be found on SDX Toolkit collection hashes 25040 bytes (the first file I grabbed as an example) in 6.94 sec (8.38 including loading from HDD), which gives about 3600 bytes/s. Sure, Atari is faster, but not twice as fast ;)
