'common' not available error notification

[MISTAnalytics]

I keep getting an error like this below:

When I manually setup a 'common' folder. I receive another error about missing the 'Cargo.toml' file in the 'crypto' folder. And then another one and another one...

I just would like to try the demo of this private-id-web solution to see if I can work with it and use it to match certain datasets together via this solution. Could you perhaps elaborate on the steps to take since the README file is not sufficient for me.

Thank you in advance!

[wyatt-howe]

Thanks for your interest in our adaptation of Private-ID! It seems we had the submodule pointed at the wrong commit. This is now fixed. Since two years ago, Rust has lost support for the wasm versions we had initially used, but we updated this as well, and everything seems to build as it should.

I updated the README with some more notes on building. Particularly, note that to properly run this between two parties in the browser you will need a setup Firebase or the like in the IO module.

Give it another try and see if that solves the issue!

[wyatt-howe]

Also, depending on how large your datasets are, you may prefer to use the original Private-ID implementing for scale.
Although with some amount of engineering effort, this could scale to millions of rows even in the browser.

Thank you for the updates, I really appreciate it.

I am a couple of steps further now. I have two questions:

1. Now, it seems the path cannot be found. I tried several statements already with a variety of paths. But it does not seem to get the path properly though. What do I do wrong?

2. You mention Firebase, but what specific part (URL) of Firebase do I need to apply to? Since Firebase consists of multiple 'solutions'. And do I need to add the key to the URL or in the io.js file?

It would be great if you could help me.

In addition to question 2: would a general web key be sufficient? --> https://firebase.google.com/docs/projects/api-keys

Certainly, I'm happy to help.

For (1) you might need to use copy rather than cp. You're the first to try this on Windows. You may also want to change the same command in package.json. This is just a shortcut command for copying the newly-built WebAssembly binaries to into the web/ directory.

For (2), I'm referring to the Firebase project configuration which should be set as the value of the firebaseConfig JSON object in io.js here. (We have it generated from an encrypted string, but you can just paste it in.)

Let me know if you're still experiencing difficulties.

@wyatt-howe,

OK, so I tried once more.

(1) I needed to manually copy the appropriate files into the folder since I could not find how to use 'cp'. 'copy' did not work either.
(2) It seems I cannot use 'cd src; cargo run --bin private-id-test' in one line. First, I needed to confirm 'cd src' and then, I needed to confirm 'cargo run --bin private-id-test'

This lead to the following result with version errors with zeroize:

(3) Regarding Firebase. I set this up and added the credentials to the io.js file. Do I need to host the Firebase app or may I use this demo locally, correct?

[wyatt-howe]

(1) Good to know. I have only ever built the library on macOS.

(2) Hmm, I'll have to look into the error with private-id-test, but you actually do not need to compile the test suite to run the demo. The web/ directory should already be good to go now that you have copied over the .wasm and .js files.

(3) Correct, you can run everything locally, such as by running python -m http.server 3000 in the web/ directory and then pointing your browser to http://localhost:3000/. That's all! You can simulate two users by opening two tabs. Hope this helps.

(1) It would be great if you could take a look at private-id-test since it still does not work, unfortunately.

(2) It seems to be very hard to use python with Nodejs. I tried everything mentioned here and restarted multiple times as well but even with python installed, Nodejs does not recognize it when I tried python -m http.server 3000 in the web directory.

I managed to set this up via this solution though (Github repo).

Now, I see this:

How may I try test CSVs and use the solution? And how may I try things that are mentioned here? I.e. PS3I, Private Join and Compute etc. Is this the exact same set up as described for the FB solution? Could you elaborate, please?

I appreciate it.

[MISTAnalytics]

@wyatt-howe

I tried the FB solution statements but this does not work, unfortunately. Could you maybe describe how to use an example json dataset to use in the test setup?

[MISTAnalytics]

@wyatt-howe

Would be great if you could help me with a test drive..? :)

[MISTAnalytics]

@wyatt-howe

Let me know.

@lapets

I tried the Facebooks solution statements but this did not work, unfortunately. Could you maybe describe how to use an example dataset to use in the test setup? A description of some steps would really help me since now I am still not able to use this though.

Appreciate it, thank you in advance.
