I am trying to use the Encrypt and decrypt String data with PGP keys example from openpgp.js but I struggle to make it work inside Firefox. openpgp.js doc

I create a keypair.

const openpgp = window.openpgp; // use as CommonJS, AMD, ES6 module or via window.openpgp



 openpgp.config.compression = openpgp.enums.compression.zlib



var options = {

 userIds: [{ name: 'Alicee', email:     'alice@example.com' }],

  numBits: 2048,

  passphrase: 'secretttoo'

};



var publicKeyAlice;

var privateKeyAlice;



 openpgp.generateKey(options).then(key     => {

privateKeyAlice = key.privateKeyArmored;

publicKeyAlice = key.publicKeyArmored;

console.log('Key generated');

console.log(privateKeyAlice);

 console.log(publicKeyAlice);



});

The keys I get consoled out are used for the example of string encryption by openpgp.js

const pubkey = '-----BEGIN PGP PUBLIC KEY BLOCK----- Version: OpenPGP.js v4.1.1'

const privkey = '-----BEGIN PGP PRIVATE KEY BLOCK----- Version: OpenPGP.js v4.1.1'

const passphrase = `secretttoo` //what the privKey is encrypted with





const encryptDecryptFunction = async() => {

const privKeyObj = (await openpgp.key.readArmored(privkey)).keys[0]

await privKeyObj.decrypt(passphrase)



const options = {

    message: openpgp.message.fromText('Hello, World!'),       // input as Message object

    publicKeys: (await openpgp.key.readArmored(pubkey)).keys, // for encryption

    privateKeys: [privKeyObj]                                 // for signing (optional)

}



openpgp.encrypt(options).then(ciphertext => {

    encrypted = ciphertext.data // '-----BEGIN PGP MESSAGE ... END PGP MESSAGE-----'

    return encrypted

})

.then(encrypted => {

    const options = {

        message: await openpgp.message.readArmored(encrypted),    // parse armored message

        publicKeys: (await openpgp.key.readArmored(pubkey)).keys, // for verification (optional)

        privateKeys: [privKeyObj]                                 // for decryption

    }



    openpgp.decrypt(options).then(plaintext => {

        console.log(plaintext.data)

        return plaintext.data // 'Hello, World!'

    })



 })

}



encryptDecryptFunction();

I get the following error in browser console:

SyntaxError: missing } after property list[Learn More] openpgp testing.html:153:27 note: { opened at line 152, column 24

How does a simple pgp encryption of string work using openpgp.js?

To actually answer your question over suggesting another library, the fix is in changeing the syntax from

message: await openpgp.message.readArmored(encrypted),

to

message: openpgp.message.readArmored(encrypted),

Then it should works since that method is not async (anymore?)

Here your example modified for symetric encryption (that's why I couldn't use jsencrypt as Nikola suggested:

 <script lang="JavaScript" src="openpgp.js"></script>

 <script lang="JavaScript">

    const options = {

        message : window.openpgp.message.fromText('Hello, World!'),     

        passwords : ['pw'],

        armor : false

    }



    window.openpgp.encrypt(options).then(ciphertext => {

        encrypted = ciphertext.message 

        return encrypted

    }).then(encrypted => {

        const options = {

            message : encrypted,   

            passwords : ['pw']                               

        }

        window.openpgp.decrypt(options).then(plaintext => {

            console.log(plaintext.data)

            alert(plaintext.data)

            return plaintext.data 

        })

    })       

</script>

The library you're trying to use doesn't look that promissing for asymetric cryptography.
If you're open for suggestion try using this one.

Here is example code :

<div class="container">

<script src="https://cdnjs.cloudflare.com/ajax/libs/jsencrypt/2.3.1/jsencrypt.js"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.js"></script>

    <script type="text/javascript">

        // Call this code when the page is done loading.

        jQuery(function () {

            // Run a quick encryption/decryption when they click.

            jQuery('#testme').click(function () {

                // Encrypt with the public key...

                var encrypt = new JSEncrypt();

                encrypt.setPublicKey($('#pubkey').val());

                var encrypted = encrypt.encrypt($('#input').val());

                console.log(encrypted);

                // Decrypt with the private key...

                var decrypt = new JSEncrypt();

                decrypt.setPrivateKey($('#privkey').val());

                var uncrypted = decrypt.decrypt(encrypted);

                // Now a simple check to see if the round-trip worked.

                if (uncrypted == $('#input').val()) {

                    alert('It works!!!');

                }

                else {

                    alert('Something went wrong....');

                }

            });

        });

    </script>
