尝试使用非ASCII装甲格式的公钥加密字符串

Question

流量：

1. 获取存储的PGP密钥
2. 这些不是ASCII装甲的键，它们已经使用openpgp.key.readArmored进行了解析
3. 尝试加密文本Hey, encrypt me.

预期：明文已加密

实际：抛出以下错误

是否可以或者我需要再次阅读装有ascii的公钥并将其结果提供到options中？

代码：

var recipients = getRecipients();
// recipients is a hashmap, key being pgp userId and value 
//   being the result of `await openpgp.key.readArmored(pubkey)`
// recipients = {
//   'bob <bob@email.com>': {
//     { keys:
//       [ { keyPacket: [Object],
//         revocationSignatures: [],
//         directSignatures: [],
//         users: [Array],
//         subKeys: [Array] } ] }
//   }  
// };

// define function to encrypt
const encrypt = async() => {
    var options = {
        message: openpgp.message.fromText('Hey, encrypt me.'),
        publicKeys: recipients['bob <bob@email.com>'].keys
    }
    openpgp.encrypt(options).then(ciphertext => {
        encrypted = ciphertext.data;
        return encrypted;
    })
    .then(encrypted => {
        console.log(encrypted);
    });
});

encrypt();

错误：
