UUID 驗證

v1~v7 版本檢測 + 時間戳提取

驗證任何UUID字符串並檢查其版本(v1–v8)、變體和時間格式(v1、v7)的嵌入式時間戳。使用生成按鈕生成密碼安全的v4或可排序的v7 UUID。示例：v7 UUID 01934567-89ab-7cde-8123-456789abcdef在其前12個十六進制數字中編碼毫秒精度時間戳。

UUID

驗證結果

✓ valid

RFC 9562

Timestamp: 2024-11-19T17:10:33.643Z

使用方法

Paste a UUID string into the input field。
Read the validation badge — green for valid, red for invalid — along with the detected version (v1–v8) and variant。
For time-based UUIDs (v1 and v7), the embedded timestamp is decoded and displayed。
Use the "Generate v4" or "Generate v7" buttons to produce a fresh UUID for testing。

範例

Pasting 01934567-89ab-7cde-8123-456789abcdef shows valid, v7, RFC 4122 variant, and a decoded millisecond timestamp。
Pasting a malformed string like "not-a-uuid" shows an invalid badge and an error message explaining the format mismatch。
