随机令牌生成器 Random Token Generator

生成可自定义长度和字符集的随机字符串,可用于临时密钥、API 测试用令牌、一次性邀请码等。
Generate random strings with customizable length and character sets for temporary keys, test tokens, one-time codes and more.

1. 设置令牌参数 · Token Parameters
推荐长度 16–64 位:
较短便于手动输入,较长更适合密钥、会话标识等。
Recommended range 16–64 characters: shorter for manual entry, longer for keys or session identifiers.
一次性批量生成多个令牌,默认每行一个。
Generate multiple tokens at once, one per line by default.
勾选不同组合来平衡“安全性”和“可读性”:
Mix different character types to balance security and readability.
• 仅字母+数字:几乎不含特殊符号,适合 URL、文件名。
• 包含符号:随机性更好,但人工输入较难。
Letters+digits: safer for URLs/file names; symbols improve entropy but are harder to type.
3. 使用小贴士 · Usage Tips
  • 适用场景 · Typical Use Cases
    • 临时 API 密钥、会话 ID、测试访问令牌。
    • 前后端联调时的假数据、Mock 令牌、一次性邀请码。
    Suitable for temporary API keys, session IDs, test tokens, mock data and one-time invitation codes.
  • 可读性 vs. 安全性 · Readability vs Security
    需要人工输入时,可勾选“去除易混淆字符”,令牌更容易辨认;如果仅由程序读写,可适当增加长度和字符种类以提高复杂度。
    When humans type the tokens, removing ambiguous characters improves readability; for machine-only use, increase length and variety to enhance complexity.
  • 重要安全说明 · Important Security Note
    本工具基于浏览器环境生成随机数,适合一般测试与日常开发使用;如涉及高强度安全要求(例如生产环境加密密钥、密码学级别令牌),请使用操作系统或专业库提供的安全随机源。
    This tool relies on randomness from your browser. It is suitable for everyday development and testing. For highly sensitive use (e.g. production cryptographic keys), always rely on OS-level or library-provided cryptographically secure random generators.

说明:生成逻辑完全在浏览器本地执行,不会上传到服务器。结果仅作示例和开发辅助使用,不构成任何安全性或合规性承诺。
Note: All generation runs locally in your browser; no data is sent to a server. The output is for demonstration and development assistance only and does not imply any security or compliance guarantee.
