密码生成器

通过可自定义的选项生成安全、随机的密码。

In an era of increasing digital threats, your first line of defense is a strong, unique password for every account. Reusing passwords or using simple, guessable words makes you an easy target for hackers. A truly secure password must be long and composed of a random mix of character types. Our Secure Password Generator allows you to create high-entropy keys that meet the strictest security requirements of banks, government agencies, and tech platforms, all while ensuring your new password is never sent over the internet.

Awaiting Professional Input

Select at least one character set to generate a password.

工作原理

The tool utilizes the `window.crypto.getRandomValues()` API, which is a cryptographically secure random number generator (CSPRNG) built into modern browsers. It creates a character pool based on your selected options and pulls values from that pool using high-entropy randomness.

计算公式

Pool_Size ^ Length = Total Combinations

Calculation Examples

1. **Simple**: 8 characters, lowercase/numbers = **~2.8 trillion combinations**. 2. **Secure**: 16 characters, all options = **~3.4e+30 combinations**.
