Issue encountered with the openpgpjs example: `'The function openpgp.encrypt is not defined'`

I encountered an issue with the 'openpgp.encrypt is not a function' error while attempting to follow the sample provided on the openpgp.js github page: https://github.com/openpgpjs/openpgpjs/blob/master/README.md#getting-started

After following the example and installing it using npm install --save openpgp

I proceeded to test the code snippets labeled 'setup' and 'Encrypt and decrypt Uint8Array data with a password'

//Set up

var openpgp = require('openpgp'); // use as CommonJS, AMD, ES6 module or through window.openpgp

openpgp.initWorker({ path:'openpgp.worker.js' }) // specify the relative web worker path

openpgp.config.aead_protect = true // enable fast AES-GCM mode (not yet OpenPGP standard)

// Encrypt and decrypt Uint8Array data with a password

var options, encrypted;

options = {
    data: new Uint8Array([0x01, 0x01, 0x01]), // input as Uint8Array (or String)
    passwords: ['confidential info'],              // multiple passwords allowed
    armor: false                              // avoid ASCII armor (for Uint8Array output)
};

openpgp.encrypt(options).then(function(ciphertext) {
    encrypted = ciphertext.message.packets.write(); // retrieve raw encrypted packets as Uint8Array
});

options = {
    message: openpgp.message.read(encrypted), // interpret encrypted bytes
    password: 'confidential info',                 // decrypt using password
    format: 'binary'                          // output as Uint8Array
};

openpgp.decrypt(options).then(function(plaintext) {
    return plaintext.data // Uint8Array([0x01, 0x01, 0x01])
});

This is the error message that appeared:

TypeError: openpgp.encrypt is not a function

Answer №1

By running the command 

npm install --save <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="4b243b2e2528303f07032d30033e">[email protected]</a>
, the version problem was successfully resolved.

For the example to function properly, it is essential to nest the decryption segment within the callback function of the encryption segment like below:

let openpgp = require('openpgp'); // import using CommonJS, AMD, ES6 module, or window.openpgp

openpgp.initWorker({ path:'openpgp.worker.js' }); // define the relative web worker path

openpgp.config.aead_protect = true; // enable quick AES-GCM mode (not currently part of OpenPGP standard)

let options, encrypted;

options = {
    data: new Uint8Array([0x01, 0x01, 0x01]), // input as Uint8Array (or String)
    passwords: ['confidential information'], // can use multiple passwords
    armor: false // do not ASCII armor (for Uint8Array output)
};

openpgp.encrypt(options).then(function(ciphertext) {
    encrypted = ciphertext.message.packets.write(); // retrieve raw encrypted packets as Uint8Array

    options = {
        message: openpgp.message.read(encrypted), // parse the encrypted bytes
        password: 'confidential information', // decrypt using the password
        format: 'binary' // output as Uint8Array
    };

    openpgp.decrypt(options).then(function(plaintext) {
        console.log(plaintext.data);
        return plaintext.data; // Uint8Array([0x01, 0x01, 0x01])
    });

});
