Text Encryption

💡 加密方法说明

  • 凯撒密码: 将每个字母按固定偏移量替换(如偏移3,A→D,B→E)
  • ROT13: 凯撒密码的特例,偏移13位,加密和解密使用相同操作
  • Atbash: 字母表反转替换(A→Z,B→Y,C→X)
  • 维吉尼亚密码: 使用关键词进行多表替换,比凯撒密码更安全
  • 反转文本: 将文本完全反转

FAQ6 questions
Is this tool safe to use?

Yes — everything runs on your device. Nothing is sent to any server, so your passwords and data stay private.

What algorithms does it use?

Industry-standard stuff. The passwords it generates are just as strong as what any premium password manager would create.

Does it need internet?

Only to load the page. Once it is open, you can disconnect and it still works.

Are the passwords actually random?

Yes. It uses your browser's built-in cryptographic random number generator — the same standard that security pros rely on.

How long should a password be?

12 characters minimum. For anything important (banking, email), go for 16+.

Where do I store the passwords?

This tool does not store them — and that is a feature, not a bug. Use a password manager like Bitwarden or 1Password to keep them safe.
