使用openpgp库在节点上运行时出现意外标识符

Question

我正在使用节点进行OpenPGP加密。这是我的参考库。当我运行一个演示，我得到以下错误。

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

openpgp.initWorker({ path:'openpgp.worker.js' })


// put keys in backtick (``) to avoid errors caused by spaces or tabs
const pubkey = `-----BEGIN PGP PUBLIC KEY BLOCK-----
...
-----END PGP PUBLIC KEY BLOCK-----`
const privkey = `-----BEGIN PGP PRIVATE KEY BLOCK-----
...
-----END PGP PRIVATE KEY BLOCK-----` //encrypted private key
const passphrase = `yourPassphrase` //what the privKey is encrypted with

const encryptDecryptFunction = async() => {
    console.log("init",openpgp)
    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)
    }
    console.log("init",options)
    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()

Answer 1

await不能在异步函数之外使用。您可以将async添加到。然后，这样您就可以在里面使用await。

.then(async(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!'
    })

})

但是我更倾向于建议按照以下方式重构代码，以消除多余的代码。您不需要它们，因为您使用Async/await。

const encryptDecryptFunction = async () => {
    console.log("init", openpgp)
    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)
    }
    console.log("init", options)
    const { data: encripted } = await openpgp.encrypt(options)

    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
    }

    const plaintext = await openpgp.decrypt(options);
    console.log(plaintext.data)
    return plaintext.data // 'Hello, World!'
}
