Yes, not cyptographically secure. But that's not the threat model, is it?
So, I carefully craft a document whose MD5 digest matches the musical
work. What shall I do? I've either created another work that the real
owner can pass of as theirs, depriving me of the benefit, or I've
created a confession of past crimes, which I can hand to the police
so that the owner, my rival composer, gets locked up.
They don't seem very likely scenarios.
However, I don't expect it to cost many more pennies to publish
several digests.
Cheers,
David.
