Why this category?
Why use security & privacy tools?
Security operations are safer when they stay local, especially when secrets or credentials are involved. These tools support testing, learning, and preparing technical values without network transmission.
They provide technical and educational assistance for checking values, creating examples, or understanding mechanisms. They do not replace a security policy or a complete audit.
Use cases
Create secure identifiers
Generate passwords, UUIDs, tokens, and random technical values.
Verify integrity
Calculate and compare file or content hashes with several algorithms.
Inspect authentication
Encode, decode, or analyze JWT, Basic Auth, and password policies.
