Can't encrypt the string in OpenPGP.js

Question

I am trying encrypt text with OpenPGP.js.

Here is an example of error: https://jsfiddle.net/7e2s516d/

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

`;

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

console.log(messageEncrypt);

I am using the latest version (5.0.0-3) of OpenPGP.js

Answer 1

It looks like you didn't check documentation of those functions.

1. encrypt, createMessage and readKey are returning a Promise, not a simple value (i.e. Message or PublicKey). Therefore you need to use those promises correctly.
2. EncryptOptions object that you pass to encrypt method should not have publicKeys property, but encryptionKeys

Once you do those changes it'll work fine.
