About UUID 生成器
生成 UUID version 4 values instantly. Use it when you need the result without the overhead of opening a larger application. For anything important, compare the output with your source and keep the original until you are satisfied with the result.
Great identifiers, poor secrets
Random UUIDs are useful for database records, test data and correlation IDs because they are easy to generate without coordinating a central counter. Their purpose is identification, not confidentiality.
Choose the UUID version your system expects. A valid UUID can still be wrong if an API contract requires a different version or a specific namespace-based format.
A realistic example
Use a UUID v4 for a local test record when the application only needs a low-collision identifier and does not require sequence or time ordering.
When this tool is not the right fit
A UUID by itself should not be used as an authentication token or password.
这个工具的作用
UUID 生成器以标准 UUID 表示形式为软件、测试和数据记录创建标识符。
