密码工具中的“无云端”真正意味着什么

“无云端”应该意味着什么

For a credential generator, “no cloud” should mean secret inputs and generated outputs are not intentionally uploaded to a service account or stored in an online credential database.

A hosted website is delivered over a network. Hosting systems can see ordinary connection metadata, and the site owner can deploy changed code. Local computation does not remove the need for HTTPS, secure deployment, and transparent dependencies.

浏览器是信任边界的一部分

Extensions, injected scripts, developer tools, clipboard managers, and malware may observe sensitive values. Use a maintained browser and avoid secret entry on untrusted devices.

离线使用

A properly cached or packaged tool may continue working offline, but users should verify the source and version. Saving an unknown webpage locally can preserve malicious code as easily as safe code.

应向任何工具提出的问题

• Are secret fields transmitted?
• Are dependencies loaded from third parties?
• Is the algorithm documented and versioned?
• Does the tool store values in local storage?
• What recovery options exist?

What “no cloud” does and does not mean

No-cloud operation can reduce dependence on a provider’s storage and account system. It does not make the device trustworthy by default. Malware, screen recording, a malicious extension, or an unlocked computer can still capture secrets.

Local tools also shift responsibility to the user. Backups, version records, recovery codes, and device security are no longer someone else’s problem.

Example choice

A user who needs family sharing and emergency access may be safer with a reputable encrypted cloud vault. A user who values offline reproducibility and understands no-recovery constraints may prefer a stateless tool. The architecture should match the real workflow.

Conclusion

“No cloud” is a design property, not a complete security guarantee. Evaluate where plaintext appears, what is stored, how recovery works, and what happens when the device is compromised.
