Choose the operation
Generating new data, encoding existing bytes and calculating a digest are different operations. Read each tool’s description before choosing it. Test fixtures and locally generated token values do not automatically become credentials accepted by a service.
Check units and destination
Distinguish characters from bytes and raw data from formatted output. Check the encoding, length and export format required by the destination. Each tool explains where processing happens and what is saved; review those details before using sensitive data.
