Feature: Shared Tokens

[benloh]

For the September 2024 pilot, we expect students to be working with multiple graphs over the duration of the pilot.

Removing the dataset field when defining tokens should make it possible to create tokens that are defined by two parameters:

• class name -- This will be the first part of the token and can be any string
• project name (group name) -- This will be the second part of the token and can be any string

There is a new script ncMakeSharedTokens(classid, projid, numTokens) that works the same as ncMakeTokens. (ncMakeTokens still works, but the datatset field is now ignored).

See #233

To Test

Test Net.Create

1. Start Net.Create with a graph, e.g. npm run dev if you already have a project defined, or ./nc.js --dataset=rome.
2. Open a browser and the developer console
3. Type ncMakeSharedTokens('history1a', 'tacitus', 30), where history1a is the name of the class and tacitus is the name of the group.
4. The system should make 30 tokens that can be used for any graph.
5. Make note of the token, e.g. HISTORY1A-TACITUS-NWE
6. Stop the current server
7. Start another graph, e.g. ./nc.js --dataset=demo
8. Log in with one of the tokens. It should work.

Test nc-multiplex

Make sure nc-multiplex can still be used to create tokens.

1. cd to nc-multiplex
2. cd to nc-multiplex/netcreate-itest
3. git fetch
4. git checkout dev-bl/shared-tokens`
5. nvm use npm ci
6. npm run package
7. cd ..
8. node nc-multiplex.js
9. Go to http://localhost/manage
10. Generate some tokens and make sure they work -- you should be able to ignore the "graph" name popup menu. Only the class id and project id fields will be used to generate the tokens. The token should match the tokens in the Net.Create test above.
11. Open a graph and use the token to sign in.

Once the user authentication system is added (post-September) this should no longer be necessary.

NOTE: This implementation essentially removes dataset from the salt for the hash. This is a problem because this essentially means that ncMakeTokens and ncMakeSharedTokens are equivalent even though that is probably not the intended behavior.

See #389 to restore ncMakeTokens
