Security and Privacy Tools Online
8 free browser-based tools
Free security tools for passwords, passphrases, JWT decoding, SHA-256 checksums, Basic Auth, CORS and CSP headers.
Security utilities are most useful when they explain what they do and what they do not do. This category includes local-first tools for inspecting tokens, generating credentials, creating checksums, and preparing security headers.
Use these tools during development, documentation, QA, infrastructure reviews, and API testing. Browser-side execution is especially important for secrets and internal examples, although users should still avoid pasting production credentials into any website unless they understand the risk.
This category supports practical security hygiene: unique passwords, readable token inspection, clear authorization headers, and safer browser policies for real web applications.
Popular Use Cases
- Generate strong passwords
- Inspect JWT claims
- Create checksums
- Build auth headers
- Draft CORS and CSP policies

Security & Privacy FAQ
Is Base64 or JWT decoding encryption?
No. Decoding makes data readable. It does not decrypt secrets or verify that a token is trusted.
Should I paste production secrets into online tools?
Avoid it unless you fully trust the tool and understand its processing. ToolsFam prioritizes local processing, but strong operational habits still matter.
What is the safest password workflow?
Generate unique high-entropy passwords and store them in a trusted password manager. Do not reuse passwords across services.
