crls must be a list of byte strings or asn1crypto.crl.CertificateList objects, not str

[anhbq97]

I'm sorry to bother you again. I'm using the following code snippet:

START CODE

response = requests.get(crl_url)

if response.status_code == 200:
      crl_data = response.content
      obj = asn1Crl.CertificateList.load(response.content)
      print(type_name(obj))

vc = ValidationContext(trust_roots=[root_cert, sub_cert], allow_fetching=False, crls=obj)

When I use from pyhanko_certvalidator._types import type_name to print out the type, it shows asn1crypto.crl.CertificateList. However, when I run it, I still get the error 'crls must be a list of byte strings or asn1crypto.crl.CertificateList objects, not str'."

I think this is just Python's duck typing getting in the way. I suspect this will go away if you replace crls=obj with crls=[obj].

I haven't checked, but I'm assuming that if you iterate over a CertificateList object, it'll use the default implementation of __iter__ from Sequence, and in the presence of _fields, that one probably returns all the field names (in other words: it probably works like a python dict).
