密码生成器
安全密码在线生成：8–64 位长度、四类字符集开关、易混淆字符过滤、去偏采样与熵值强度评级。

Entropy math
Strength is estimated as length × log2(poolSize) bits — truly random selection from the enabled sets. Roughly: 40+ bits resists most casual attacks, 60+ bits is solid for online accounts, 90+ bits is overkill against offline cracking with current hardware. Because selection is uniformly random from a crypto RNG — not from a human “strong-looking” pattern — the estimate is trustworthy. The ambiguous filter removes look-alike characters (0 O 1 l I |) that cause transcription errors in person.
如何使用密码生成器
设置长度、勾选字符集，生成——每一条都来自浏览器的加密随机源，而不是较弱的 Math.random 回退。复制按钮把结果直接送进密码管理器，需要多条凭据时批量生成。
当密码需要口述或从纸面誊录时，开排除易混字符：l/1、0/O 这类歧义对直接消失。强度提示按启用的字符池计算；生成结果在你复制之前只存在于浏览器里。
