I just released a new version of PyKCS11, a Python wrapper above the PKCS#11 API.

See PyKCS11 introduction or PyKCS11’s documentation.

The project is registered at Pypi: https://pypi.org/project/PyKCS11/

Explanation

This version only fixes a problem on Windows.

In version 1.5.19, I upgraded the PKCS#11 header file pkcs11.h to version PKCS#11 3.2. Execution of automatic tests failed on Windows. I then disabled failed test. But I, in fact, disabled all the tests on Windows. And the problem went unnoticed.

Version 1.5.19 did not contain the code required to pack the structures on Windows. So the PyKCS11 wrapper and the PKCS#11 library were not alligned on the data format. And crash...

Changes:

1.5.20 - September 2026, Ludovic Rousseau
