设置安全级别

【Setting security levels】

要调整 Node.js 应用中的安全级别，你可以在加密字符串中包含 @SECLEVEL=X，其中 X 是所需的安全级别。例如，要在使用默认 OpenSSL 密码列表的情况下将安全级别设置为 0，可以使用：

【To adjust the security level in your Node.js application, you can include @SECLEVEL=X within a cipher string, where X is the desired security level. For example, to set the security level to 0 while using the default OpenSSL cipher list, you could use:】

import { createServer, connect } from 'node:tls';
const port = 443;

createServer({ ciphers: 'DEFAULT@SECLEVEL=0', minVersion: 'TLSv1' }, function(socket) {
  console.log('Client connected with protocol:', socket.getProtocol());
  socket.end();
  this.close();
})
.listen(port, () => {
  connect(port, { ciphers: 'DEFAULT@SECLEVEL=0', maxVersion: 'TLSv1' });
});const { createServer, connect } = require('node:tls');
const port = 443;

createServer({ ciphers: 'DEFAULT@SECLEVEL=0', minVersion: 'TLSv1' }, function(socket) {
  console.log('Client connected with protocol:', socket.getProtocol());
  socket.end();
  this.close();
})
.listen(port, () => {
  connect(port, { ciphers: 'DEFAULT@SECLEVEL=0', maxVersion: 'TLSv1' });
});拷贝

这种方法将安全级别设置为 0，允许使用传统功能，同时仍然利用默认的 OpenSSL 加密算法。

【This approach sets the security level to 0, allowing the use of legacy features while still leveraging the default OpenSSL ciphers.】
