I have just dumped code into a Chrome console and saved a cert while in a pinch. It’s not best practices of course, but when you need something fast for one-time use, it’s nice to have something immediately available.
You could make your own webpage that works in the browser (no backend) and make a cert. I haven’t published anything publicly because you really shouldn’t dump private keys in unknown websites, but nothing is stopping you from making your own.
That’s what NodeJS and Deno are.
The point of the browser support means it runs on modern Web technologies and doesn’t need external binaries (eg: OpenSSL). It can literally run on any JS, even a browser.
Just going to mention my zero-dependency ACME (Let’s Encrypt) library: https://github.com/clshortfuse/acmejs
It runs on Chrome, Safari, FireFox, Deno, and NodeJS.
I use it to spin up my wildcard and HTTP certificates. I’ve personally automated it by having the certificate upload to S3 buckets and AWS Certificates. I wrote a helper for Name.com for DNS validation. For HTTP validation, I use HTTP PUT.

I can spend 2 minutes scanning a page for a certain word every time I need to search for something.
But I’m very happy somebody spent the time to code Ctrl+F.

Don’t use JSON for the response unless you include the response header to specify it’s application/json. You’re better off with regular plaintext unless the request header Accept asked for JSON and you respond with the right header.
That also means you can send a response based on what the request asked for.
403 Forbidden (not Unauthorized) is usually enough most of the time. Most of those errors are not meant for consumption by an application because it’s rare for 4xx codes to have a contract. They tend to go to a log and output for human readers later, so I’d lean on text as default.

Something something ground loop detection, maybe.
I’ve also used .local but .local could imply a local neighborhood. The word itself is based on “location”. Maybe a campus could be .local but the smaller networks would be .internal
Or, maybe they want to not confuse it with link-local or unique local addresses. Though, maybe all .internal networks should be using local (private) addresses?
I’ve been using uBOLite for about a year and I’m pretty happy with it. You don’t have to give the extension access to the content on the page and all the filtering on the browser engine, not over JavaScript.
The way his content is structured and edited is like junk food for your brain. There’s a formula that appeals to the least lowest common denominator and he (his team) excels at it.
The topics he picks usually hit some nerve of vicariousness (game shows contestants) or suspense from wanting to know what happens next (challenges and clickbait).
I just recently started working with ImGui. Rewrite compiled game engines to add support for HDR into games that never supported it? Sure, easy. I can mod most games in an hour if not minutes.
Make the UI respond like any modern flexible-width UI in the past 15 years? It’s still taking me days. All of the ImGui documentation is hidden behind closed GitHub issues. Like, the expected user experience is to bash your head against something for hours, then submit your very specific issue and wait for the author to tell you what to do if you’re lucky, or link to another issue that vaguely resembles your issue.
I know some projects, WhatWG for one, follow the convention of, if something is unclear in the documentation, the issue does not get closed until that documentation gets updated so there’s no longer any ambiguity or lack of clarity.
My open-source, zero dependency JS library for requesting and generating certs with dns01: https://github.com/clshortfuse/acmejs
I only coded for name.com but it is compatible with anything really. Also can run in the browser, which could be useful in a pinch.
Either do a left join and repeat all the post values for every tag or do two round-trip queries and manually join them in code.
JSON_ARRAYAGG. You’ll get the object all tidied up by database in one trip with no need to manipulate on the receiving client.
I recently tried MariaDB for a project and it was kinda neat, having only really messed with DynamoDB and 2012 era MsSQL. All the modern SQL languages support it, though MariaDB and MySQL don’t exactly follow the spec.
Yeah, except for the first few bytes. PKCS8 has some initial header information, but most of it is the OCTET_STRING of the private key itself.
The PEM (human “readable”) version is Base64, so you can craft up a string and make that your key. DER is that converted to binary again:
/**
* @see https://datatracker.ietf.org/doc/html/rfc5208#section-5
* @see https://datatracker.ietf.org/doc/html/rfc2313#section-11
* Unwraps PKCS8 Container for internal key (RSA or EC)
* @param {string|Uint8Array} pkcs8
* @param {string} [checkOID]
* @return {Uint8Array} DER
*/
export function privateKeyFromPrivateKeyInformation(pkcs8, checkOID) {
const der = derFromPrivateKeyInformation(pkcs8);
const [
[privateKeyInfoType, [
[versionType, version],
algorithmIdentifierTuple,
privateKeyTuple,
]],
] = decodeDER(der);
if (privateKeyInfoType !== 'SEQUENCE') throw new Error('Invalid PKCS8');
if (versionType !== 'INTEGER') throw new Error('Invalid PKCS8');
if (version !== 0) throw new Error('Unsupported PKCS8 Version');
const [algorithmIdentifierType, algorithmIdentifierValues] = algorithmIdentifierTuple;
if (algorithmIdentifierType !== 'SEQUENCE') throw new Error('Invalid PKCS8');
const [privateKeyType, privateKey] = privateKeyTuple;
if (privateKeyType !== 'OCTET_STRING') throw new Error('Invalid PKCS8');
if (checkOID) {
for (const [type, value] of algorithmIdentifierValues) {
if (type === 'OBJECT_IDENTIFIER' && value === checkOID) {
return privateKey;
}
}
return null; // Not an error, just doesn't match
}
return privateKey;
}
I wrote a “plain English” library in Javascript to demystify all the magic of Let’s Encrypt, ACME, and all those certificates. (Also to spin up my own certs in NodeJS/Chrome).
Edit: To be specific, PKCS8 is usually a PKCS1 (RSA) key with some wrapping to identify it (the OID). The integers (BigInts) you pick for RSA would have to line up in some way, but I would think it’s doable. At worst there is maybe a character or two of garbage at the breakpoints for the RSA integers. And if you account for which ones are absent in the public key, then anybody reading it could get a kick out of reading your public certificate.
