使用说明与常见问题How-to & FAQ
「线性反馈移位寄存器示意（Fibonacci LFSR）」是什么？What is the Linear Feedback Shift Register Demo (Fibonacci LFSR) tool?
简单 Fibonacci LFSR：设定位宽、1-based 抽头、种子和步数，逐步输出二进制状态。仅教学示意，勿用于密码学。本地处理。Simple Fibonacci LFSR: set width, 1-based taps, seed and steps, then list binary states. Teaching demo only - not for cryptography. Processed locally.
如何使用「线性反馈移位寄存器示意（Fibonacci LFSR）」？How do I use the Linear Feedback Shift Register Demo (Fibonacci LFSR) tool?
在「线性反馈移位寄存器示意（Fibonacci LFSR）」中，按需设置「位宽」、「抽头（从 1，逗号分隔）」、「种子（整数）」、「步数」等选项，然后点击「运行」按钮即可。In the Linear Feedback Shift Register Demo (Fibonacci LFSR): Set "Width", "Taps (1-based, comma)", "Seed (int)", "Steps", then click "Run".
能用于生成安全随机数吗？Is this safe for cryptography?
不能。短 LFSR 可预测，仅供理解反馈移位。请用系统 CSPRNG。No. Short LFSRs are predictable - teaching only. Use a system CSPRNG.
抽头怎么编号？How are taps numbered?
从 1 到位宽：1 是最低位，位宽是最高位（Fibonacci 反馈）。From 1 to width: 1 is the least-significant bit, width is the MSB (Fibonacci feedback).
有哪些选项可以调整？What options can I adjust?
「线性反馈移位寄存器示意（Fibonacci LFSR）」的设置：「位宽」默认 8；「抽头（从 1，逗号分隔）」默认 8,6,5,4；「种子（整数）」默认 1；「步数」默认 16。每次生成结果都按当前设置处理。Settings in the Linear Feedback Shift Register Demo (Fibonacci LFSR) — "Width" default 8; "Taps (1-based, comma)" default 8,6,5,4; "Seed (int)" default 1; "Steps" default 16. The result always uses the current settings.
代码或数据会被上传吗？Is my code or data uploaded?
不会。「线性反馈移位寄存器示意（Fibonacci LFSR）」完全用 JavaScript 在本地运行，适合处理含有密钥、内部接口等敏感内容的数据。No. The Linear Feedback Shift Register Demo (Fibonacci LFSR) runs entirely in local JavaScript, so it is safe for data containing keys or internal endpoints.
