Use cases

When these tools help

Create a strong password and store it in a password manager.
Checksum a file or string to see if input changed.
Seed mock integrations with clearly labeled test keys.

Using security tools responsibly

Password generators help length and randomness. Copy results straight into a password manager rather than reusing them across sites.

Hash outputs show whether data changed; they are not a substitute for encryption or proper password hashing with salt on servers.

Generated API-key-shaped strings are for mocks and local tests. Label them as non-production and never commit them as real secrets.

JWT decoding inspects claims; signature verification still belongs on your backend.
