Hello, I am wondering if there is a limitation on the size of hash that can be used to
embed and validate. IE, why has this not moved to a more resilient hash?
Thanks so much!

Hi,
I'm not a project maintainer but from my PoV this project is a bit in
maintenance mode so I don't expect such a change. Also change of the
hash algorithm should be done as a separate project probably -- it would
mean renaming anyway. And honestly, I would expect that there are better
alternatives now (did not looked for them so I might be wrong).
Brian, I guess you are the best person to ask about the project (based
on the number of contributions. What do you think?
Best Regards,
Jirka

There may be enough space to use a different hash, but I don't see any
compelling reason to switch. md5 is still useful for integrity checking
which is all that this is doing. It's not a crytographic check of the
iso, it's main purpose is to let users know that something went wrong
when they wrote it onto a CD, DVD, or flash drive so that they don't run
into unexpected errors during the install.
FWIW it does use a string that starts with 'ISO MD5SUM = ' so in theory
it could switch to a different algorithm and maintain backwards
compatibility. It has 512 bytes available to use for the data.
