javascript - openpgpjs 示例中的错误 : 'openpgp.encrypt is not a function'

Question

在尝试 openpgp.js github 页面上给出的示例时，我收到“openpgp.encrypt 不是函数”错误:https://github.com/openpgpjs/openpgpjs/blob/master/README.md#getting-started

按照所提供的示例并使用npm install --save openpgp安装后

然后我尝试了标记为“设置”和“使用密码加密和解密 Uint8Array 数据”的片段

// Set up

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

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

openpgp.config.aead_protect = true // activate 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: ['secret stuff'],              // multiple passwords possible
    armor: false                              // don't ASCII armor (for Uint8Array output)
};

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

options = {
    message: openpgp.message.read(encrypted), // parse encrypted bytes
    password: 'secret stuff',                 // decrypt with password
    format: 'binary'                          // output as Uint8Array
};

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

这是错误:

使用npm install --save openpgp@2.2.1安装解决了版本问题。

此外，为了使示例正常工作，解密部分需要嵌入到加密部分的回调函数中，如下所示:

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

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

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


var options, encrypted;

options = {
    data: new Uint8Array([0x01, 0x01, 0x01]), // input as Uint8Array (or String)
    passwords: ['secret stuff'],              // multiple passwords possible
    armor: false                              // don't ASCII armor (for Uint8Array output)
};

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

    options = {
        message: openpgp.message.read(encrypted), // parse encrypted bytes
        password: 'secret stuff',                 // decrypt with password
        format: 'binary'                          // output as Uint8Array
    };

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

});
