What kills me is there was a lot of discussions going back and forth about why or why not people should be able to use the tool "which should not be named" to actually get nsp/update/dlcs for themselves. There was also a lot of talk about how people should just use sites and discords to download the files that people who have access to the tool would upload. Since then, there has been lots of questions from people about where these sites were and there has been a lot of negativity towards these people for asking. This is supposed to be a community. Instead of talking smack or just saying "use other sources" and not posting them, is not helping anyone. To answer everyone's questions:
Use the site that was mentioned by Enkuler above and when on the site (Make sure it says Decode from Base64 format)
Paste in the Base64 code that you are finding on the discord.
Click Decode
There you go. Enjoy!
