Documentation for nanogram available here for awhile
Edit:
Dont be a ungrateful Be nice pls. I put a lot of time, effort, and my own money into making this. I’m choosing to freely share it :)
Yes I get help from LLM’s. Review the code if you think it’s unsafe, or just move on and don’t use it. Happy to answer any technical questions.
Edit 2: Expanded source code for termux version here.
Edit 3: Expanded source for pi version here
Is that an inaccurate claim? It should provide the means to organize and communicate securely…to the extent Tor is secure, and if your using the official Tor browser, web crypto can be utilized for group and 1-1s for an additional layer of encryption. I thought it was a fine claim. It should be able to handle quite a few people messaging all at once on the PI varient.
How would you ever discover a filename?
If you did have a filename and the exact url to the image you would need to be logged in as a valid user, and the person who shared the photo would have needed to allow access to their profile.
Even if you have the correct link, if those two conditions arnt satisfied you will not be able to view.
This was a design choice to have consistency in filetypes. What’s the downside? All browsers will support displaying a jpg.
Which part are you talking about? The image compression is defined as the compress and store function.
The “API reference” in the readme goes into further specifics on how this works with flask.
Everything except the login page, registration link will behind these two checks see (def login) where the @loginrequired logic is defined for each of the app routes.
Tor doesn’t automatically secure your app. If your social media instance has 1000 users on it, and one user gets compromised, then the other 999 users shouldn’t have any interactions outside of that user leaked.
Are file uploads encrypted?
Maybe you have a data leak. Maybe they send the filename in plaintext somewhere. Maybe they take advantage of the fact that UUIDs might be deterministic. But if I may flip the question… Why does an inaccessible post even need to return 403 anyway? It just functions as a big footgun that may cause any other exploits to behave worse.
But you can determine its existence or not through the status code.
Gifs will lose any animation, pngs will lose quality. Also, as far as I can tell, there’s nothing stopping a malicious user uploading a non-image file.
There are two steps to making a post: Upload and store the image and add the post to the database. There’s also similar steps to deleting a post: Removing the image upload and removing the post from the database. Are both these operations atomic?
It’s not that hard for a sufficiently motivated adversary to get an account on a sufficiently large instance. You need to ensure that one user account being compromised doesn’t result in information leakage from unrelated accounts.
This discussion stems from issues I found in just one function. You’re making a product which requires a very high level of security. You need to understand how to write secure code, and your LLM won’t be able to do it for you.
I don’t want to discourage you from programming in general, but making a very secure social media site is a rather complex undertaking for someone new to programming.
