Cómo se manejan los datos
Security tools do not write plaintext, passwords, private keys, or secrets to logs or database storage. Browser-only password generation stays local.
Preguntas frecuentes
Should I use these tools for production secrets?
Use them for testing and development. Production secrets should be handled inside your controlled security environment.
Are passwords or private keys stored?
No. Security inputs are processed for the current operation only and are not stored.
Which AES mode should I prefer?
AES-GCM is generally recommended when authenticated encryption is compatible with your workflow.
