Node openpgp error when encrypting: Could not find valid key packet for encryption in key

Question

I have a error when trying to encrypt a string with a pgp public key: 'Could not find valid key packet for encryption in key 9ae788ff8eec0b31'

This error doesn't appear with every key but with most of them. Here one of the keys that errors:

-----BEGIN PGP PUBLIC KEY BLOCK-----
Version: BCPG v1.43

Here is the function im using to encrypt

    const openpgp = require('openpgp')
    async function pgpEncrypt(pubkey, message) {
        await openpgp.initWorker({ path: 'openpgp.worker.js' })
        const options = {
            message: await openpgp.message.fromText(message), // input as Message object
            publicKeys: (await openpgp.key.readArmored(pubkey)).keys, // for encryption
            armor: false
        }
        const cipherText = await openpgp.encrypt(options)
        return cipherText.data
    }

What's wrong with this? how can i ensure the key works with this library?

Answer 1

It is a version issue. Try the 4.10.8 version of openpgp. Use the following lines for the dependencies.

"dependencies": {
  "openpgp": "^4.10.8"
}
