How to choose the right security tools

These utilities support safe development tasks such as encoding data, generating passwords, inspecting tokens, and checking metadata.

Before you use a tool

  • Do not treat encoding as encryption.
  • Avoid pasting live credentials, production tokens, or personal data into any online tool.
  • Verify security-sensitive results in the environment where they will be used.

A practical workflow

Use test data where possible, inspect the result, and perform cryptographic verification or authorization checks in trusted application code.
