## Download
Please, go to the [Release page](https://github.com/polhenarejos/pico-openpgp/releases "Release page")) and download the UF2 file for your board.
Note that UF2 files are shiped with a dummy VID/PID to avoid license issues (FEFF:FCFD). If you are planning to use it with OpenSC or similar, you should modify Info.plist of CCID driver to add these VID/PID or use the VID/PID patcher as follows: `./patch_vidpid.sh VID:PID input_openpgp_file.uf2 output_openpgp_file.uf2`
Please, go to the Release page and download the UF2 file for your board.
Note that UF2 files are shiped with a dummy VID/PID to avoid license issues (FEFF:FCFD). If you are planning to use it with OpenSC or similar, you should modify Info.plist of CCID driver to add these VID/PID or use the [Pico Patcher tool](https://www.picokeys.com/pico-patcher/).
Alternatively you can use the legacy VID/PID patcher as follows:
`./patch_vidpid.sh VID:PID input_hsm_file.uf2 output_hsm_file.uf2`
You can use whatever VID/PID (i.e., 234b:0000 from FISJ), but remember that you are not authorized to distribute the binary with a VID/PID that you do not own.
Note that the pure-browser option [Pico Patcher tool](https://www.picokeys.com/pico-patcher/) is the most recommended.
## Build
Before building, ensure you have installed the toolchain for the Pico and the Pico SDK is properly located in your drive.
