Still using MD5 for download hash?!

I was having trouble matching a hash displayed in the downloads section with the file I had downloaded, when I noticed it was MD5.
As per the powershell help:
For security reasons, MD5 and SHA1, which are no longer considered secure, should only be used for simple change
validation, and should not be used to generate hash values for files that require protection from attack or tampering.

MD5 should be sufficient

I just don't have the space to put longer hashes. Any ideas?

Hmm maybe show the first half(ish) with a drop-down "v" that expands to the full thing like "System Specs" does?

Or maybe a a longer hash split over two lines?

(SHA256)


Or a really small font? :)

From a cryptography perspective, showing off the first 16 bytes of SHA512 would be more secure than MD5.

Maybe you can show off the first 16 Bytes, with an ellipsis + tooltip for the rest of the hash if anyone hovers over it. No one is eyeballing all 128 characters of SHA512 anyway, the first 16 bytes / 32 characters will be sufficient.

That's what your "truncated with ellipsis" achieves. Not sure about showing the full hash in the tooltip or just make the truncated a link that says "click to show full hash", so you can mark and copy (not everybody knows to compare only the first characters)

Edit: I made some changes, thoughts?
