A colleague sent me a python script that does asn1 encoding. It
starts with:
import asn1
then after a few
asn1_enc.write(oid, asn1.Numbers.ObjectIdentifier)
There's no way that would work without something else being involved.
You only imported "asn1". That can't give you something called
"asn1_enc", so you're not showing enough for us to help you.
It seems pyasn1 is already installed. It does not provide asn1_enc.
python3-pyasn1 is the only Python asn1 library available. It provides a
package called "pyasn1" that you can import.
I am pretty sure this is just old or broken code. According to the
documentation:
https://python-asn1.readthedocs.io/en/latest/usage.html
… you would just create a new asn1.Encoder() object and use that to
write(). Perhaps “asn1_enc” is defined that way in the code?
I think this isn’t really a Fedora issue, unless the API changes in
F38, in which case, it’s time to update the code, or pin your
requirements to an older version of asn1.
He is actively doing this. I believe he uses Ubuntu.
asn1 is a 3^rd party package that I installed from pip under the name
pyasn1 IIRC. You would import it in your code using:
The README for python3-pyasn1 says that it is the one that you would get
from "pip install pyasn1" so it should be the right one.
import asn1
The import is "pyasn1" in Fedora as it should be, but that still won't
get you the thing you're looking for, so you need to provide some more
lines of the code to see where that's coming from.
