More information

OS version: Raspbian GNU/Linux 11 (bullseye) on Raspberry Pi Zero
uname -a : Linux epaper 5.10.63+ #1488 Thu Nov 18 16:14:04 GMT 2021 armv6l GNU/Linux

On Raspberry Pi Zero, the cryptography module version 36.0.1 results in "Illegal Instruction". Downgrading to 36.0.0 doesn't produce any error.

This is the specific wheel that gets downloaded when I pip install cryptography: https://www.piwheels.org/simple/cryptography/cryptography-36.0.1-cp39-cp39-linux_armv6l.whl

As a simple test I ran

python3 -c "from cryptography.fernet import Fernet"

And the output is "Illegal Instruction"

I tried to do a gdb but I don't actually know what I'm doing or what the output means, but hopefully there's something in here that helps.

pi@epaper:~ $ gdb --args python3 -c "from cryptography.fernet import Fernet"

Verified, same here on armv6l RPi models, hence RPi 1 and Zero (1). This one was built manually @bennuttall, probably not on a Raspbian OS with armv6l toolchain? https://github.com/piwheels/packages/issues/267#issuecomment-1005201010

[bennuttall]

This issue has been identified and we hope to fix asap. Follow in #276

[bennuttall]

The wheels have been rebuilt and this issue should now be resolved

Tested and working thanks.
