Try this [https://www.socsci.ru.nl/wilberth/computer/pic.html calculator] to make these checksums yourself.

If you install the [https://extensions.openoffice.org/en/project/cryptographic-hash-functions-uno-component-openofficeorg cryptographic hash] extension to Open Office/ Libre Office you can use [https://www.socsci.ru.nl/wilberth/nocms/computer/pic.ods this document] to calculate PIC. You may have to enable macros for it to work.

==== Google Sheets ====
You can also calculate the PICs with this [https://docs.google.com/spreadsheets/d/18jmxpui2rr3dShySQiyn06kX36cCHHGRgan2MGGXjlo/edit?usp=sharing Google Sheet].
You can also calculate the PICs with this [https://docs.google.com/spreadsheets/d/18jmxpui2rr3dShySQiyn06kX36cCHHGRgan2MGGXjlo/edit?usp=sharing Google Sheet].
==== Python 3 ====
In Python 3 you can easily calculate pic. Note that the secret and the ppn must be strings.
#!/usr/bin/env/python3
secret = "mySecret123!"
ppn = "0"
pic = hashlib.sha256(secret.encode('utf-8')+ppn.encode('utf-8')).hexdigest()[0:4].upper()
print(pic)
