Can I create new individual users via the rest API, post to principal, with argon2 secrets?

[JanAxelJonsson]

I make a call via the REST API to create a new individual, to the call /principal

with hash from 'openssl paswd -6' it works, for example '$6$m15MG2vGAQG0rWN/$9H5YokW.Xgu1YRPKRNhJ67gR/wFz33pTZ.5akE95X8nwlgqZgocxtZiq9eg5NoaqK/pKfCVYoTbRzB0x8yO5P1';
with an ardon2 hash is does not work, se below (the api call works, but the user 'kalle' can not login, get invalid password.
I am testing with a stalwart installation that is totally setup with defaults, no config changes:

data in the POST call to API/principal

data {
type: 'individual',
name: 'kalle',
description: 'kalle petterson',
secrets: [
'$argon2id$v=19$m=64000,t=3,p=1$pAbSHQuc4pTL7C11mNsJHA$9U1V0RxsZGKgG7l8jHBl9igRurbW4wil3ZruS2ad2e8'
],
emails: [ '[email protected]' ],
roles: [ 'user' ]
}

question, is it possible to do this way? Do I need to add argon2 support to stalwart?

this is the way I do calulate hashes:

//node.hs myhash.js:

import child_process from "node:child_process";
import util from "node:util";
import * as argon2 from "argon2";
import * as crypto from "crypto";

//own dependencies
import logger from "./logger.js";

// silly exec "openssh" shell version of sha512 -- WORKS
const execFile = util.promisify(child_process.execFile);
export async function hashPasswordOpenSSL(password) {
logger.info('myhash.js','hashPasswordOpenSSL-password',password);
const { stdout } = await execFile("openssl",
["passwd", "-6", password]);
return stdout.trim(); // e.g. "$6$$"
}

//argon2 version -- DOES NOT WORK WITH STALWART
const hashingConfig = { // based on OWASP cheat sheet recommendations (as of March, 2022)
parallelism: 1,
memoryCost: 64000, // 64 mb
timeCost: 3 // number of itetations
}

export async function hashPasswordArgon2(password) { ////// this is the call used
let salt = crypto.randomBytes(16);
return await argon2.hash(password, {
...hashingConfig,
salt,
})
}

export async function verifyPasswordWithHashArgon2(password, hash) {
return await argon2.verify(hash, password, hashingConfig);
}

Solved: Just changed from adding user "kalle" to "jan and it work.
I did add and remove user kalle around 13 times, messed up something in stalwart?
