Ok let’s say i have a web server that produces a dynamically generated image that is linked to that event. I want to place that url in the event itself. Can’t do this because the url contains the event id.
Should I just maintain a database that links my own randomly generated urls with event ids?
The idea for u tag came from trying to avoid having to do that
They are messing with you. You will never be able to use a SHA-256 hash of some content inside the content itself. Making the URL hash match the event id hash, when the URL is inside the event, is like having Bitcoin's proof of work at the maximum difficulty possible. Not even the hash rate of the entire bitcoin network can solve that for you.
Vitor: What about extra layer to adopt mainstream? Today it's pubkey/private key. What about "brainwallet" way? Example: email and password. It would guarantee unique "brain wallet" key. User would not need to know/see that it creates a private/Public key.
Impossible without centralizing the conversion between user + password into the private key.
Just to give you an idea, without centralizing it, the "e-mail" would have to use 22 words to represent it. It would be VERY long.
No. Use same logaritm as brain wallets use. Example: https://brainwalletx.github.io/
There is no lower or upper limit to create a private/public key. You can create a key pair using a single space even.
Also, you could support this in Amethyst alone and let the user see/get his private key after login, to be used in other clients.
just use NIP-33
Here’s an answer that everyone will hate: cram the image content into the note either in content or a custom tag field.
That way, the signed event contains the payload image at all times. No need for external storage.
How is it "linked" to the event? The image has the event id in itself?
Looks like you're trying to do a very cool thing for no reason. Just make a random or serial URL for the image and shove it into the event.
