AFAIK the best public MD5 preimage attack is at 2^123.4. Dividing it in half (50% chance of finding collision) gives 7.0×10^36. If you generated distinct hashes with multiple GPUs at speeds of 200 billion/sec, you would find a match with those odds in 1.1 billion billion years (7.0×10^36/(200×10^9×60×60×24×365.2524) ≈ 1.1*10^18) (the universe is 14 billion years old).
I don't get the last part?
I agree it's probably very hard to achieve, but it's still possible.
Is this a reason to keeping using a very-hard-to-break but still vulnerable hashing algorithm?
If the discussion is about what color is best, you win...
How hard can it be :(: https://www.google.com/search?q=preimage+vs+collision
@Det: Some more detailed articles:
As a cryptography ignorant, I'm not gonna tell anybody what algorithms they should use. However, cryptography experts deprecated md5sum algorithm long time ago, and recommended using stronger ones such as sha256sum & sha512sum since. Beside this, even if md5sum was super-safe today, I think nobody can argue that sha256sum & sha512sum are safer. So, why using a weaker hashing algorithm?
Thank you!
That's a really poor article. Have a look at the actual MD5 one, along with collision vs. preimage resistance.
"MD5 algorithm is no longer deemed secure. [...] the use of a newer hashing tool such as sha256sum is recommended."
Source: https://en.wikipedia.org/wiki/Md5sum
Recommended algorithms (sha512sum is the strongest, and the preferred option for many people):
I hope it helps!
Becaaaause?
Please stop using md5 for checksums. Thanks!
Fixed again.

Direct downloads are no longer available. Create your Oracle account, download, and put in with the PKGBUILD.
New and improved. Now you can just download to ~/Downloads then run the update.
