GitHub API secret encryption with libsodium in Node.js：UnhandledPromiseRejectionWarning：Error：bad public key size

我想通过GitHub REST API设置一个仓库密码。我使用文档中的示例：

const sodium = require('tweetsodium');
const key = "base64-encoded-public-key";
const value = "plain-text-secret";
// Convert the message and key to Uint8Array's (Buffer implements that interface)
const messageBytes = Buffer.from(value);
const keyBytes = Buffer.from(key, 'base64');
// Encrypt using LibSodium.
const encryptedBytes = sodium.seal(messageBytes, keyBytes);
// Base64 the encrypted secret
const encrypted = Buffer.from(encryptedBytes).toString('base64');
console.log(encrypted);

字符串
我收到这个错误：

Problem：如何正确加密和解密密钥，以便在我的API中使用？
解决方案：@Topaco提到需要使用base64编码的密钥，比如2Sg8iYjAxxmI2LvUXpJjkYrMxURPc8r+dB7TJyvvcCU=，解决了上面描述的错误。
已编辑

我将在不同的仓库中使用不同的密钥。我应该为每个仓库生成一个新的base64编码密钥吗？

示例代码不太清楚key实际上是什么以及从哪里获得它。您需要从/repos/{owner}/{repo}/codespaces/secrets/public-key端点获得的“存储库公钥”。
将存储库公钥与新secret中的值一起使用：

const key = "base64-encoded-public-key"; // this is the repository public key you need to fetch from GitHub
const value = "plain-text-secret"; // the secret value

字符串
然后，您可以创建或更新密钥：

const res = await octokit.actions.createOrUpdateRepoSecret({
    owner: "GITHUBUSER",  
    repo: "GITHUB_REPO", 
    secret_name: "KEY_NAME", 
    encrypted_value: encrypted,
  });

这是我使用的代码。

const crypto = require('crypto');
const sodium = require('tweetsodium');
const { Octokit } = require("@octokit/core");
// Create a personal access token at https://github.com/settings/tokens/new?scopes=repo
const octokit = new Octokit({ auth: process.env.GH_PERSONAL_ACCESS_TOKEN });
module.exports = async () => {
  const encryptionKey = crypto.randomBytes(16).toString('hex');
  const publicKeyResponse = await octokit.request('GET /repos/<USERNAME>/<REPO>/actions/secrets/public-key');
  const publicKey = publicKeyResponse.data.key;
  const publicKeyId = publicKeyResponse.data.key_id;
  // Convert the message and key to Uint8Array's (Buffer implements that interface)
  const messageBytes = Buffer.from(encryptionKey);
  const keyBytes = Buffer.from(publicKey, 'base64');
  // Encrypt using LibSodium.
  const encryptedBytes = sodium.seal(messageBytes, keyBytes);
  // Base64 the encrypted secret
  const encryptedEncryptionKey = Buffer.from(encryptedBytes).toString('base64');
  await octokit.request('PUT /repos/<USERNAME>/<REPO>/actions/secrets/ENCRYPTION_KEY', {
    owner: '<USERNAME>',
    repo: '<REPO>',
    secret_name: 'ENCRYPTION_KEY',
    key_id: publicKeyId,
    encrypted_value: encryptedEncryptionKey,
  });
  return encryptionKey;
};
