🔢 生成随机数字对Generate Random Digit Pairs
生成随机两位数字对（00-99）。本地处理。可设置「个数」、「种子（留空 = 安全随机）」、「每行一个」。Generate random two-digit pairs (00-99). Processed locally. Settings: How many, Seed (blank = secure random), One per line.
使用说明与常见问题How-to & FAQ
「生成随机数字对」是什么？What is the Generate Random Digit Pairs tool?
生成随机两位数字对（00-99）。本地处理。可设置「个数」、「种子（留空 = 安全随机）」、「每行一个」。Generate random two-digit pairs (00-99). Processed locally. Settings: How many, Seed (blank = secure random), One per line.
如何使用「生成随机数字对」？How do I use the Generate Random Digit Pairs tool?
在「生成随机数字对」中，按需设置「个数」、「种子（留空 = 安全随机）」，结果会实时显示在下方，点击「复制结果」即可复制。In the Generate Random Digit Pairs: Adjust "How many", "Seed (blank = secure random)"; the result appears below instantly — click "Copy result" to copy it.
范围是多少？What range is used?
每对数字从 00 到 99，共 100 种，前导零会保留（例如 07），每种出现的概率相同。可以每行一对，也可以用空格分隔。Each pair is 00 to 99, 100 possibilities with leading zeros kept (such as 07), all equally likely. Output can be one per line or space-separated.
结果是真随机的吗？「种子」有什么用？Is the output truly random? What does Seed do?
「种子」留空（默认）时，结果用浏览器的 crypto.getRandomValues（密码学安全随机数）生成，每次都不同，每种结果出现的概率相同（偏差小于千万亿分之一）。填写种子后改用确定性的伪随机数生成器（mulberry32）：同一种子总是得到同样的结果，便于复现，但结果可以被预测，不要把带种子的结果用于密码或需要公证的抽奖。With Seed left blank (the default), the output comes from the browser's crypto.getRandomValues (cryptographically secure randomness), so it differs every time and every outcome is equally likely (any bias is below one in a million billion). If you enter a seed, a deterministic pseudo-random generator (mulberry32) is used instead: the same seed always gives the same output, which is handy for reproducing a result, but it is predictable, so do not use seeded output for passwords or audited draws.
输入和输出是什么样的？What does the input and output look like?
例如在「生成随机数字对」中把「个数」设为 3，「种子」设为 1，输出为：83 12 82。For example, in the Generate Random Digit Pairs with "How many" set to 3, "Seed" set to 1, the output is: 83 12 82.
有哪些选项可以调整？What options can I adjust?
「生成随机数字对」的设置：「个数」默认 10；「种子（留空 = 安全随机）」可留空；可勾选：「每行一个」。每次生成结果都按当前设置处理。Settings in the Generate Random Digit Pairs — "How many" default 10; "Seed (blank = secure random)" optional; tick boxes: "One per line". The result always uses the current settings.
