About UUID Generator
Last updated: May 2026
OptiPix UUID 生成器直接在您的浏览器中使用加密安全的随机数生成来创建通用唯一标识符。可以生成单个或批量 UUID(一次最多 100 个),格式包括 v4(随机)、v1(基于时间戳)、v7(现代 Unix 时间戳 + 随机)或 Nil 格式。您可以选择五种显示格式:带连字符的标准格式、不带连字符的格式、大写格式、URN 格式或带花括号的格式。通过粘贴任何 UUID 来验证它 - 该工具将识别其版本并确认其有效性。可以导出以换行符、逗号分隔的批量 UUID,或作为 JSON 数组导出。可以复制单个 UUID 或一次性复制所有 UUID,并将批量结果下载为 .txt 文件。所有生成过程均使用 crypto.getRandomValues() 来实现加密随机性。没有任何信息会被发送到任何服务器 - 您的 UUID 完全在您的设备上生成。
How It Works
该工具使用 Web Crypto API(v4 使用 crypto.randomUUID(),v1 和 v7 使用 crypto.getRandomValues())来生成加密安全的随机字节,然后根据 RFC 4122 UUID 规范进行格式化,包含正确版本和变体位。
Use Cases
- •为数据库记录生成唯一标识符
- •为 API 请求跟踪和关联创建 UUID
- •为软件配置文件生成 GUID
