### > Rescue Pico HSM Tool and Commissioner
Pico HSM Tool implements a new CCID stack to rescue the Pico HSM in case it has wrong VID/PID values and it is not recognized by the OS. It can be accessed through `pico-hsm-tool.py` or [Pico Commissioner](https://www.picokeys.com/pico-commissioner/ "Pico Commissioner").

## Security considerations
All secret keys (both asymmetric and symmetric) are encrypted and stored in the flash memory. The MKEK, a 256-bit AES key, is used to protect these private and secret keys. Keys are held in RAM only during signature and decryption operations, and are loaded and cleared each time to avoid potential security vulnerabilities.

For advanced usage scenarios, refer to the documentation and examples provided. Additionally, the Pico HSM supports the SCS3 tool for more sophisticated operations and includes features like multiple key domains. For detailed information on SCS3 usage, refer to [SCS3 documentation](/doc/scs3.md).
### Important
OpenSC relies on PCSC driver, which reads a list (`Info.plist`) that contains a pair of VID/PID of supported readers. In order to be detectable, you have several options:
- Use `pico-hsm-tool.py` to modify VID/PID on-the-fly.
- Use the pure-browser online [Pico Commissioner](https://www.picokeys.com/pico-commissioner/ "Pico Commissioner") that commissions the Pico Key on-the-fly without external tools.
- Build and configure the project with the proper VID/PID with `USB_VID` and `USB_PID` parameters in `CMake` (see [Build section](#build "Build section")). Note that you cannot distribute the patched/compiled binary if you do not own the VID/PID or have an explicit authorization.
