About this collection
Practical security tools, without the clutter.
Security utilities need clear boundaries. A hash is not encryption, decoding a JWT does not verify its signature, and a strong password still needs safe storage and phishing-resistant account protection.
These tools perform focused calculations locally and explain the result in context. Do not paste live secrets into any device or browser you do not trust.
Worth checking: Use production secrets only on a trusted, up-to-date device. A browser tool cannot protect data from malware, screen capture or an already-compromised account.
