This is not working for me, openPGP just freezes:

import openpgp from 'openpgp';

const publicKeyArmored = `-----BEGIN PGP PUBLIC KEY BLOCK-----

`;

let messageEncrypt = await openpgp.encrypt({
    message: await openpgp.createMessage({ text: 'test' }),
    publicKeys: await openpgp.readKeys({ armoredKey: publicKeyArmored }) // This promise never resolves
});

console.log(messageEncrypt);

However, if I read the key from disk using below approach it works:

import { readFileSync } from 'fs';
import openpgp from 'openpgp';

const armoredKeys = readFileSync('./public.key.asc', {
    encoding: 'utf8',
});

let messageEncrypt = await openpgp.encrypt({
    message: await openpgp.createMessage({ text: 'test' }),
    publicKeys: await openpgp.readKeys({ armoredKey: publicKeyArmored })
});

console.log(messageEncrypt); // Totally works

Since I'm eventually retrieving the key from AWS Secrets Manager I will have to treat it as a string and not a file on disk. I've tried using \n newline in the hardcoded string key, but doesn't make any difference.

What am I missing?
