Hello , want to test my SmartCard-Reader with the sample get token information. The sample is from the Docu 1.5.2, after testing the script the compiler throw an error.

Describe what did happen.

Error: Module 'PyKCS11' has no 'CKF_DIGEST' member

Please provide the full output of the execution of the program.

What do you call "the Docu 1.5.2"?

Hello,

I only can find the documentation of PyKCS11 version 1.5.2, on my device i have the version 1.5.9 of PyKCS#11

I wanted to test my SmartCard-Reader from Omnikey AG 6121 mobile from cryptas, wth the sample code

For testing i have take the example-code "Get token information" from https://pkcs11wrap.sourceforge.io/api/samples.html#get-token-information

i get an error in the method getMechanismInfo(self, slot=

def getMechanismInfo(self, slot): print(" Mechanism list: ") m = self.pkcs11.getMechanismList(slot) for x in m: self.colorize(" ", x) i = self.pkcs11.getMechanismInfo(slot, x) if not i.flags & PyKCS11.CKF_DIGEST: if i.ulMinKeySize != PyKCS11.CK_UNAVAILABLE_INFORMATION: self.colorize(" ulMinKeySize:", i.ulMinKeySize) if i.ulMaxKeySize != PyKCS11.CK_UNAVAILABLE_INFORMATION: self.colorize(" ulMaxKeySize:", i.ulMaxKeySize) self.colorize(" flags:", ", ".join(i.flags2text()))

My Editor shows the Error:

Error: Module 'PyKCS11' has no 'CKF_DIGEST' member (which is bold marked)

So my question is, if something has changed in the newer version of PyKCS11.

I only found the Documentation of the Version 1.5.2

A big thank you in advance

I can't reproduce your problem. It works fine for me.

$ python3
Python 3.7.6 (default, Dec 30 2019, 19:38:26) 
[Clang 11.0.0 (clang-1100.0.33.16)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import PyKCS11
>>> print(PyKCS11.CKF_DIGEST)

CKF_DIGEST is still defined. You have a problem with your PyKCS11 installation.

Have you tried the Debian package python3-pykcs11? https://packages.debian.org/sid/python3-pykcs11

Hello Ludovic,

I think you are right in thinking that I have problems with the installation, I installed the library with pip3, then deleted it and installed the package with apt-get again,

The first attempt was via venv, and in venv using pip3

to install the packages PyKCS11 and asn1crypto, which works, but again the problem is that I can't import the PyKCS11 library.

your suggestion via CLI print(PyKCS11.CKF_DIGEST) worked for me too.

Try to include an external library of the manufacturer, but I get an error here too. Since I am new to Python, I guess that I am not able to include the library of the manufacturer correctly.

See the screenshot, if he can't find the PyKCS11 library when importing, do I have to consider anything else?

Many thanks in advance

I guess the file /usr/lib/x86-athena/libASEP11.so does not exist or, more probably, is for Intel x86 CPU and not ARM CPU (used by the Raspberry Pi).

Your problem is not with PyKCS11 itself.

Hello,

You are probably right, as you can see from the screenshot, I try to include the library dynamically, but it is still not found or ignored.
