[silly talk] ngc is a ridiculous tool that nvidia has it's for people who have been mind controlled by the corporate ai to work on data science. it's downloadable from their website at https://ngc.nvidia.com/setup/installers/cli although you might need to give them your social security number or something to download it. [/silly talk] On their website:
Check the binary's md5 hash to ensure the file wasn't corrupted during download:
md5sum -c ngc.md5
Yay, verifying download integrity using md5. Hum, there's no hash on the website.

Yay! _The md5 to verify against is bundled in the same download._ Did you know that TCP has protection against non-malicious corruption too? https://en.wikipedia.org/wiki/Transmission_Control_Protocol#Checksum_computa... As does the zip format; https://en.wikipedia.org/wiki/Zip_%28file_format%29#Local_file_header The point of manually verifying a digest is for _cryptographic integrity_. It doesn't work if the digest is bundled with the data. It doesn't work if the digest is md5. The only reason to _pretend_ you are doing that is to help mitm attackers modify files in transit. One sees this pattern a lot of places. WHAT ARE WE SUPPOSED TO MAKE OF IT? Story: "I got my new prosthetic brain in the mail! Hum, the postman was that guy in the wanted poster." "Yay! Make sure to verify it's the right one before replacing your old one with it." "How do I do that?" "Ask the postman!" "Okay. Um, guy from the wanted poster, is this the right brain? I can throw out my old one?" "Yes! I only deliver the right brains!" "YAY!" The recipient of the brain proceeds to go on a bankrobbery, and gives the funds to the postman. Here's another story: "Yay! Let's go on a drive!" "Make sure you don't get hurt if there's a car crash!" "A car crash what's that?" "That's what we have seatbelts for!" "Seatbelts? What are those?" "Aren't you worried you might hit somebody?" "No! My government protects me from car crashes!"
