OAuth 2.0 Token Introspection with NGINX and njs

This configuration enables NGINX to validate an authentication token against an authorization server by using OAuth 2.0 Token Introspection (RFC 7662). This solution uses the auth_request module and the NGINX JavaScript module to require authentication and perform the token introspection request.

By default, the client's authentication token is expected as a bearer token supplied in the Authorization header. If supplied elsewhere in the HTTP request, the $access_token variable must be configured to specify where to obtain the token.

Token introspection requests are authenticated. By default, the $oauth_client_id and $oauth_client_secret variables are used to perform HTTP Basic authentication with the Authorization Server. If only the $oauth_client_secret variable is specified then that value is used

• BIP32 - is a method for generating a tree of private keys from a master private key.
• BIP39 - is a method for encoding 128-256 bits of random data into 12-24 word phrases from a list of interchangeable 2018 words, and then turn those phrases into a 64-byte hash.
• BIP44 - is a method for structuring a private key tree in a specific way that will facilitate usage/restoration/discovery of multiple accounts for multiple purposes.

Git Subtree Basics

If you hate git submodule, then you may want to give git subtree a try.

Background

When you want to use a subtree, you add the subtree to an existing repository where the subtree is a reference to another repository url and branch/tag. This add command adds all the code and files into the main repository locally; it's not just a reference to a remote repo.

When you stage and commit files for the main repo, it will add all of the remote files in the same operation. The subtree checkout will pull all the files in one pass, so there is no need to try and connect to another repo to get the portion of subtree files, because they were already included in the main repo.

Adding a subtree

Let's say you already have a git repository with at least one commit. You can add another repository into this respository like this:

function rfc3339(d) {
    
    function pad(n) {
        return n < 10 ? "0" + n : n;
    }

    function timezoneOffset(offset) {
        var sign;
        if (offset === 0) {
            return "Z";

// then press enter. It has fuzzy matching, so "y", "Y", "yes", "YES", and "Yes" all count as
// confirmations. If the input is not recognized, it will ask again. The function does not return
