I don't understand what's the harm of having a releases page with a binary and its md5 hash, or how that keeps anyone from just compiling an unofficial binary themselves and adding malware to it.

Anyone not technical enough to compile a binary has to give up trying to use it or risk some unnoficially distributed executable .

An md5 can be created for the trojaned binary and be posted along with it.

Not to mention that the md5 checksum is a very poor choice for this purpose because of the ease of creating md5 collisions.

But not on the official page, right? And there's nothing stopping someone from doing that now is there? I don't see how the original authors providing binaries is less secure than anything else.

Yeah but still hackers can abuse SEO and direct visits to their pages. If you are not careful you might accidentally download a malicious binary.

The official page can be hacked, and both malware and md5 of the malware can be placed there.

That's the whole point of using a cryptographic signature backed by a web of trust instead of a mere hash.

Where would the hash be advertised?
