Error: Error encrypting message: No keys, passwords, or session key provided.

[adrian-badulescu]

What I'm trying to do:

• get some Azure storage blobs from container DIDE and encrypt them with RSA 2048 and upload them in other container called encrypted-dide
  These blobs are downloaded through a stream and recomposed by func. streamToString(readableStream)
  (I'm not using streams openpgp Js streams, as I don't know if Microsoft streams are the same with NodeJs ones)

• the publicKey is harcoded in the file keys.js and and is:

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

-----END PGP PUBLIC KEY BLOCK-----`

until here my code works as I have done tests with not encrypted text

I have followed the official documentation of openpgp js and some Internet resources.

• The error I am getting is: Error: Parameter [message] needs to be of type Message

• The code is:

const { BlobServiceClient } = require('@azure/storage-blob');
// const { v1: uuidv1 } = require('uuid');
// const stream = require('stream').promises
const openpgp = require('openpgp');
// import * as openpgp from 'openpgp'
const { publicKey } = require('./keys')





async function main() {

    const AZURE_STORAGE_CONNECTION_STRING = process.env.AZURE_STORAGE_CONNECTION_STRING;
    const blobServiceClient = BlobServiceClient.fromConnectionString(AZURE_STORAGE_CONNECTION_STRING);
    const containerClient = blobServiceClient.getContainerClient("uploadebs");
    const containerEncryptedFiles = blobServiceClient.getContainerClient("encrypted-dide");
    await containerEncryptedFiles.createIfNotExists("encrypted-dide") 
    
   // console.log(await openpgp.readKey({ armoredKey: publicKey })) <- THIS WORKS!
    for await (const blob of containerClient.listBlobsFlat()) {

        if (blob.name.match('^DIDE*')) {
            const blockBlobClient = containerClient.getBlockBlobClient(blob.name);
            const encryptedblockBlobClient = containerEncryptedFiles.getBlockBlobClient(blob.name)
            blockBlobClient.download(0)
            .then(downloadBlockBlobResponse => streamToString(downloadBlockBlobResponse.readableStreamBody))
            .then(blobAsString => {
    return Promise.all([openpgp.createMessage({ text: blobAsString }), openpgp.readKey({ armoredKey: publicKey })])
    .then(([message, publicKeys ])=>{
        return openpgp.encrypt({
            message,
            publicKeys,
        });
    }) // BELOW LINE, SENDS TEXT IN BLOBS, ENCRYPTED OR NOT THROUGH FUNC UPLOAD
            .then(encrypted => {encryptedblockBlobClient.upload(encrypted, encrypted.length)})    
})

        }
    }

}

async function streamToString(readableStream) {

  
    return new Promise((resolve, reject) => {
        const chunks = [];
        readableStream.on("data", (data) => {
            chunks.push(data.toString());
        });

        readableStream.on("end", () => {
            resolve(chunks.join(""));
        });
        readableStream.on("error", reject);
    });
}

main().then(() => console.log('Done')).catch((ex) => console.log(ex.message));

Hi @adrian-badulescu , openpgp.createMessage is async, you need to await it .

[adrian-badulescu]

Hi @larabr,

I have changed the code accordingly and the error now is <<<Error: Error encrypting message: No keys, passwords, or session key provided.>>>

[larabr]

In v. 5.0.0-3 we changed the option names for openpgp.encrypt (among others): publicKeys has been renamed to encryptionKeys .

[adrian-badulescu]

In the official documentation you are still using denomination publicKeys, not encryptionKeys, the confusion was served :)

[larabr]

This will be fixed with the new pre-release, you can look at the README on Github for the updated examples (#1330).
